When to Upgrade an Industrial Switchboard: A Guide for Plant Managers

The Asset Nobody Thinks About Until It Fails

A main switchboard can sit in a plant room for thirty years doing its job without attention. Production equipment around it is replaced two or three times. Loads are added. The original drawings go missing. Then one day a breaker fails and there is no replacement, or an inspection finds heat damage on a busbar, or a new machine cannot be connected because there is nowhere to put it.

A switchboard upgrade is a significant project, and it is far better planned than forced. This guide sets out the signs that an industrial switchboard is due for attention, the standard that now applies to new boards, the options short of full replacement and how to plan the work around production.

Eight Signs a Switchboard Needs Attention

Heat. Discolouration, a hot smell, or hot spots found by thermal imaging. Heat means resistance, and resistance means a connection or component that is failing.

Nuisance tripping. Breakers that trip without an obvious fault are often overloaded, worn or reacting to harmonics.

No spare capacity. Every way is used, and new circuits are being squeezed in or doubled up.

Obsolete components. Breakers and parts that are no longer manufactured, with replacements available only second hand.

Fault level exceeded. A supply upgrade or a new transformer has raised the fault current beyond what the board was built to withstand.

Corrosion and contamination. Moisture, dust and cleaning chemicals attacking metalwork and insulation, which is common in food and beverage plants.

No documentation. No current drawings, no test records and labels that do not match what is connected.

Unsafe to work on. Exposed live parts when a door is opened, no segregation between sections, and no way to isolate one part without shutting down the whole board.

Any one of these is worth an inspection. Several together mean the board is a risk to production and to people.

The Standard Changed

Low voltage switchboards in Australia are now built to the AS/NZS 61439 series, which replaced AS/NZS 3439. The older standard had been in place since 2002 and was superseded on 24 May 2021. In Queensland the transition period during which a board could be built to either standard ended on 25 November 2022.

The series has several parts. AS/NZS 61439.1 sets the general rules and AS/NZS 61439.2 covers power switchgear and controlgear assemblies, which is the part relevant to most industrial switchboards.

The important change is in how a board is proven. The old distinction between type tested and partially type tested assemblies has gone. In its place is design verification, in which the manufacturer must demonstrate compliance against 13 constructional and performance requirements, covering matters such as temperature rise, short circuit withstand and clearances. Verification of the forms of internal separation is mandatory.

Queensland’s Electrical Safety Office has issued guidance on the standard as it applies to switchboards with a connected load exceeding 125 amps or a fault level of 10 kA or greater, which takes in most industrial main and distribution boards.

What That Means for an Existing Board

A switchboard that complied when it was built does not become unlawful because the standard changed. The new standard matters in three situations. When you buy a new board, it must be built and verified to AS/NZS 61439, and you should ask for the design verification evidence. When you modify an existing board, the modification has to be safe and should not undermine the basis on which the board was originally verified. And when you weigh up repair against replacement, the old board’s inability to meet current expectations for segregation and arc fault protection is a legitimate factor.

A common mistake is to add circuits to an old board without anyone checking the busbar rating, the fault rating or the temperature rise. Each addition is small. Together they produce a board loaded well beyond its design.

Three Options

Repair and maintain. If the board is structurally sound and parts are available, cleaning, retightening, replacing worn components and restoring labels and drawings may buy many more years. This suits a board that is old but not obsolete.

Retrofit. The enclosure and busbars are kept and the switchgear is replaced, often with modern breakers on adaptor kits. This can restore protection performance and parts availability at lower cost and with a shorter outage than replacement. It does not fix an undersized busbar or an inadequate fault rating.

Replace. A new board built to the current standard, sized for the load you have and the load you expect. This is the answer where capacity, fault rating, condition or safety cannot be recovered any other way.

The decision usually turns on four questions. Is the fault rating adequate for the supply? Is there capacity for the next ten years? Can parts still be bought new? Can it be worked on safely?

Planning a Replacement

A switchboard replacement is mostly a planning exercise. The installation itself may take a weekend. The preparation takes months.

Load study. Measure what the board actually supplies, using logged data over a representative period, and allow for known growth.

Fault level. Establish the prospective fault current from the supply so the new board is rated correctly.

Specification. Form of internal separation, spare capacity, metering, provision for power factor correction, arc fault containment, enclosure rating for the environment and the protection philosophy.

Lead time. Custom switchboards take time to design, build and verify. Order early.

Changeover method. Decide whether the new board goes in the same position, which means a full outage, or alongside the old one so circuits can be transferred in stages.

Temporary supply. Identify what cannot be without power during the changeover, such as refrigeration and tank cooling, and arrange generators or temporary feeds.

Shutdown window. Fit the changeover into a planned shutdown and agree the sequence with production.

Testing and handover. Verification testing, a certificate of testing and compliance, updated single line diagrams and circuit schedules, and protection settings recorded.

What It Costs Not to Plan

The expensive version of this project is the one that follows a failure. An emergency replacement means days or weeks of lost production waiting for a board to be built, temporary supplies hired at short notice, a compromised specification because there is no time to get it right and, often, a like for like replacement that carries the old board’s limitations into the next thirty years.

A condition assessment costs a small fraction of that and gives you the information to decide in your own time.

Where to Start

Have the board inspected by an industrial electrician, with thermal imaging under load. Find or recreate the single line diagram. Establish the fault level and compare it with the board’s rating. List the components that are obsolete. Measure the load. With those five things in hand, the choice between repair, retrofit and replacement usually becomes clear.

Electrical Maintenance for Manufacturing Plants: Building a Planned Programme

Electrical Failures Give Warning, if Anyone Is Looking

Mechanical wear announces itself. Bearings get noisy, chains slacken, belts fray. Electrical deterioration is quieter. A termination loosens a little more each time the cable heats and cools. A drive’s cooling fan slows. Dust builds on a contactor. Nothing looks wrong until the afternoon a switchboard trips and takes half the plant with it.

Most of these failures are detectable weeks or months in advance with simple tests. A planned electrical maintenance programme is how a plant finds them on its own timetable. This guide sets out what the regulations require in a Queensland manufacturing plant, what good practice adds, and how to build a programme that fits around production.

The Legal Minimum in a Queensland Manufacturing Plant

Queensland’s electrical safety regulation sets inspection and testing requirements according to the type of work carried out at a workplace, and manufacturing work has its own rules. They apply to what the regulation calls specified electrical equipment, which is equipment with a current rating of not more than 20 amps and includes extension leads and portable outlet devices.

Double insulated equipment must be inspected, tested and tagged at intervals of no more than 12 months.

Equipment that is not double insulated must be inspected, tested and tagged at intervals of no more than 6 months.

Fixed safety switches need a push button test at least every 6 months and an operating time and current test at least every 12 months.

Portable safety switches are not permitted in manufacturing work at all.

Testing and tagging must be done by a person appointed as competent by their employer, and the relevant standard is AS/NZS 3760. These are minimum intervals. Equipment in harsh areas, such as washdown zones, deserves more frequent attention.

Why the Minimum Is Not a Maintenance Programme

Notice what those rules cover: portable equipment, leads and safety switches. They are aimed at protecting people from electric shock, which is essential. They say almost nothing about the switchboards, motor control centres, drives and motors that keep a plant producing. A site can be fully up to date with testing and tagging and still be weeks away from a major electrical failure.

A maintenance programme has to cover both: the safety obligations and the reliability of the fixed plant.

Start With an Electrical Audit

You cannot plan maintenance for equipment you have not listed. An electrical audit is a condition survey of the site that produces an asset list, a description of the condition of each item and a ranked list of what needs attention.

A useful audit report separates findings into three groups: safety issues that need action now, reliability risks that should be scheduled, and observations to watch. It includes photographs. It also tells you where your documentation is missing, which is usually the first thing to fix.

What a Good Programme Covers

Thermal imaging. An infrared camera shows loose connections, overloaded circuits and failing components as hot spots, long before they fail. It is non-contact and is done with the plant running, because the equipment must be under load for a problem to show. For many plants an annual survey of every switchboard and motor control centre, timed a few months before the shutdown, gives the best return of any electrical maintenance task.

Switchboards and motor control centres. With the power off: cleaning, checking terminations for tightness, inspecting contactors and breakers for wear and heat damage, checking door seals and verifying that labels match the drawings.

Motors. Insulation resistance testing to track winding condition over time, current measurement on each phase, and a look at terminal boxes for moisture. A falling insulation reading is a clear early warning.

Variable speed drives. Cleaning or replacing filters, checking cooling fans, confirming enclosure temperatures and backing up parameters. Heat is what kills drives, and blocked filters are the usual cause.

Control systems. PLC and HMI backups taken and verified, memory backup batteries replaced on schedule, control power supplies checked and panel cooling confirmed.

Safety systems. Functional tests of emergency stops, guard interlocks and light curtains, with the results recorded.

Standby and emergency systems. Uninterruptible power supplies and their batteries, emergency and exit lighting, and any standby generator.

Field wiring. Cables that flex, glands in wet areas and junction boxes exposed to washdown. In food and beverage plants, water ingress is behind a large share of electrical faults.

Setting the Frequencies

Apart from the regulated intervals, there is no single correct frequency. Set it by criticality and environment. A drive on the main filler in a warm, wet area warrants monthly attention to its filters. A distribution board in a dry store may need a look once a year.

A practical structure has four tiers. Short operator level checks done weekly, such as looking for damaged leads and blocked panel vents. Monthly or quarterly tasks done by an electrician during planned maintenance stops. Annual tasks such as thermal imaging and motor testing. And invasive work on switchboards, which needs the power off and belongs in the shutdown.

Review the frequencies after a year. If a task never finds anything, do it less often. If it finds something every time, do it more often or fix the underlying cause.

Working Around Production

Electrical maintenance has a constraint that mechanical maintenance does not share. In Queensland, electrical work on or near energised equipment is generally prohibited, so most hands-on work inside a panel needs that panel isolated. That means maintenance has to be planned into stops: changeovers, weekly maintenance windows and the annual shutdown.

The answer is to sort tasks by what they need. Thermal imaging and visual inspections can be done while running. Tasks on one machine fit into that machine’s planned stops. Switchboard work that affects a whole area is grouped for the shutdown, where the electrical scope should be agreed weeks ahead so that parts are on hand and isolations are planned.

Records That Earn Their Keep

A maintenance programme without records is a series of unconnected visits. Keep the test and tag register, safety switch test results, thermal images from each survey so that changes can be compared, motor insulation readings as a trend, backup dates and a log of every fault with its cause.

These records satisfy auditors and insurers. More usefully, they show which assets are deteriorating and justify replacing them before they fail.

Is It Worth the Cost

The comparison is simple to make for your own plant. Take the cost of one hour of lost production on your main line and multiply it by the hours lost to electrical faults last year. Then compare that with the cost of a thermal survey, a few planned maintenance days and a shutdown scope. In most plants the programme pays for itself by preventing a single serious failure.

How Skilled Labour Hire Powers Shutdowns, Upgrades and Peak Season in FMCG Plants

The Three Moments Every FMCG Plant Needs More Hands

Most of the year, a well run FMCG plant hums along with the team it has. Then come the moments that break the routine: the annual shutdown, the line upgrade that has been on the capital plan for two years, and the peak season surge when every pallet the plant can produce is already sold. Each of these moments has the same characteristic. For a short, critical window, the site needs far more skilled trades capacity than it employs, and the cost of getting it wrong is enormous.

Queensland’s beverage and food manufacturers face all three regularly, with the summer peak hitting harder here than almost anywhere in the country. This article looks at how skilled labour hire, planned properly, turns these high stakes windows from a scramble into a controlled operation.

Shutdowns: Where Every Hour Is Paid For Twice

A maintenance shutdown is the most expensive time your plant will ever buy. Every hour of the window costs you twice: once in the labour and materials being spent, and once in the production not happening. The economics therefore reward one thing above all else, which is finishing on time. And the most common reason shutdowns overrun is not parts or planning, it is trades capacity. Too few people, or people without the right skills, and the critical path stretches.

Labour hire transforms shutdown economics because it lets you resource the plan rather than plan around your resources. If the work list needs twelve trades for five days, you can field twelve trades for five days, then return to your normal crew. The essential caveat is skill matching. A shutdown work list on a beverage line might span seamer overhauls, conveyor rebuilds, drive replacements, control panel work and safety system validation. That calls for genuine industrial electricians, fitters and turners, not general hands, and it calls for a provider who can technically vouch for every person they send.

Planning matters as much as people. BevTech, which supports shutdowns across Queensland FMCG sites, publishes a Shutdown Planning Checklist through its website precisely because the sites that plan early, lock in labour early and sequence work realistically are the ones that hand the plant back on schedule.

Upgrades and Projects: Extra Capacity Without Losing Your Team

Capital projects create a different staffing problem. A line upgrade, a new filler, a palletiser replacement or a control system migration needs skilled people for weeks or months, but pulling your own trades onto the project starves daily maintenance, and the plant still has to run. The classic failure mode is a project delivered late by an exhausted team while the reliability of the rest of the plant quietly deteriorates.

Supplementary labour solves the arithmetic. Either hired trades backfill routine maintenance while your own people, who know the plant best, deliver the project, or experienced project trades join the upgrade directly under your supervision. Providers with real engineering pedigree add a further option: taking on defined packages of the work itself. BevTech’s project history in FMCG includes designing and building can inverter block systems for bottle and can rotation, refrigeration PLC control systems for beer tank temperature management, and hot water rinse CIP systems for can seamers, delivered as turnkey packages alongside supplying labour. Having one partner able to flex between supplying people and delivering scope gives project managers valuable room to move.

Peak Season: Queensland’s Summer Test

Every beverage manufacturer in Queensland knows what October to March means. Volumes climb, lines run longer, changeovers multiply, and the maintenance team that was adequate in June is suddenly stretched across double the operating hours. Equipment worked harder fails more often, and a breakdown in peak season does not just cost downtime, it costs orders that competitors will happily fill.

The plants that sail through summer treat peak staffing as a plannable event, not an emergency. They forecast the extra trades hours the season will demand, book skilled contractors months ahead, and bring them in early enough to complete inductions and learn the plant before the crush arrives. Because the peak repeats every year, the smartest sites bring back the same contractors season after season, compounding site knowledge instead of resetting it. A provider with a stable pool of FMCG experienced trades makes that continuity possible.

What These Three Windows Have in Common

Shutdowns, upgrades and peaks all reward the same behaviours. Plan early, because the best people are booked first. Specify skills honestly, because a warm body who cannot do the work is worse than a gap you knew about. Choose a provider who understands FMCG environments, because hygiene protocols, CIP systems and food safety requirements are not things you want to teach from scratch during your most critical week. And keep one eye on the relationship beyond the immediate window, because the provider who staffed your shutdown well is the one you will want at 2am when something breaks in January.

Safety and Induction: Do the Boring Work Early

One theme deserves its own mention, because it quietly decides whether extra labour helps or hurts: inductions and safety integration. A shutdown or peak season brings a wave of unfamiliar people onto site at exactly the moment supervision is stretched thinnest, and the statistics on contractor injuries during maintenance windows are sobering across the industry. The fix is unglamorous. Book inductions weeks ahead rather than burning the first morning of the shutdown on them. Issue permits, isolation procedures and site rules to the provider in advance so their people arrive already briefed. Confirm every licence and high risk work ticket before day one, not after. And insist your provider shares this load; a specialist will have induction records, verified qualifications and safety documentation ready before being asked, because they have done this dance on dozens of FMCG sites. An hour of administration in the planning phase is worth ten on the day, and it is worth infinitely more than an incident.

Why We Are Giving Away Our Shutdown Planning Checklist

The Most Expensive Week on Your Production Calendar

Ask any engineering or maintenance manager in a beverage or FMCG plant to name the most stressful week of their year and the answer is rarely a breakdown. It is the planned shutdown. A shutdown is the one window where every deferred job, every capital project and every compliance item competes for the same few days, with a restart date that production has already promised to the business. Every hour of that window is paid for twice, once in labour, parts and contractor costs, and again in the production the line is not running.

After more than 25 years of shutdown and project work in Australian beverage and FMCG plants, we have seen shutdowns that restarted early and shutdowns that dragged a week past their date. The difference between them is almost never how hard people worked during the window. It is the quality of the scoping and planning done in the weeks before anyone picked up a tool. That conviction is why we have put our shutdown planning approach into a practical document, the FMCG and Beverage Plant Shutdown Planning Checklist, and made it freely available to download from our website.

Why Give It Away?

The honest answer is that well planned shutdowns are better for everyone, including us. When we arrive on site for shutdown work, the jobs that run smoothly are always the ones where the scope was locked early, the parts were sighted on the shelf, and the control system changes were written and tested before the window opened. The jobs that turn into overruns are the ones scoped on the back of a purchase order three weeks out.

We would rather work with plants that plan properly, and we would rather be part of that planning early, when engineering input can still change the outcome. Sharing the checklist costs us nothing except a few trade secrets that were never really secrets, because none of this is complicated. It is simply the discipline of doing the right things in the right order, starting earlier than feels necessary.

There is also a simpler reason. Our business is family owned and has been built over decades on long relationships with manufacturers, from the largest names in Australian beverage production through to smaller regional operations. Useful, practical help has always been how those relationships start.

What Poor Planning Actually Costs

The visible cost of an overrun is easy to calculate: extra contractor hours, weekend penalty rates, expedited freight on the part that should have been ordered six weeks earlier. The larger cost is the one on the production side. A high speed canning or bottling line produces enormous value per hour, and every hour the restart slips is product that was promised to customers and is now not coming. In a contract packing environment, a late restart can mean penalties or a customer quietly moving volume elsewhere.

Then there are the costs that never appear on a spreadsheet. Work rushed at the end of an overrunning shutdown is work done tired, under pressure, with testing compressed or skipped. That is how a shutdown intended to improve reliability ends up causing the next three months of niggling faults. It is also how safety shortcuts happen, and in our view no schedule is worth that.

Against all of this, the cost of proper planning is a few structured meetings, a master work list, and the discipline to order long lead items on time. It is the cheapest insurance available in plant engineering.

Where Shutdowns Go Wrong

The failure patterns repeat across almost every site. Scope arrives late, added in the final fortnight by people who were not in the early meetings, and every late addition bumps something else off the critical path. Long lead items are ordered on optimistic assumptions, so the gearbox or the PLC hardware arrives the day after the window closes. Contractor crews are booked late in shutdown season, when the good tradespeople are already committed. And control system work is treated as something that happens during the shutdown, rather than something developed and bench tested beforehand, so the window that should have been used for installation and commissioning gets consumed by programming.

That last one deserves special attention, because it is the most common gap we see. PLC changes, HMI updates, drive replacements and safety circuit modifications all need engineering time before the shutdown and structured testing time during it. When we delivered the automated control system for two glycol refrigeration units cooling large beer tanks, built on a Siemens 1500 series PLC, the logic was developed and proven before installation, which is precisely why commissioning went to plan. The same applied to the hot water rinse system we implemented for a can seamer clean in place process on a Siemens 1200 series platform. Control work rewards preparation, and punishes improvisation.

What the Checklist Covers

The checklist is a working document, not a glossy brochure. It walks through six phases of a shutdown, starting eight to twelve weeks out and finishing after the line is handed back. The early sections cover building a single master work list across mechanical, electrical and automation scopes, ranking every job by production risk, and identifying the design, fabrication and long lead items that decide your critical path. The middle sections deal with parts, people and engineering readiness: confirming deliveries in writing, locking in contractor crews, backing up every PLC, HMI and drive parameter set, and walking every job at the machine before the window opens.

The later sections cover the shutdown itself and what follows: protecting the critical path shift by shift, testing safety functions as they are reinstated, recommissioning system by system, and holding the review that makes the next shutdown easier. Each item exists because we have watched its absence cost a plant real money.

One recommendation in the checklist is worth highlighting here. A shutdown window is the cheapest opportunity you will ever get to deal with control system obsolescence. Legacy Allen Bradley and Siemens hardware moves steadily through manufacturer lifecycle stages, and a planned migration during a scheduled window costs a fraction of an emergency migration after a failure. If your site has processors that have run untouched for fifteen years, the next shutdown is the time to act, and the checklist prompts you to assess exactly that.

How to Use It

Download it, print it, and take it into your next shutdown planning meeting. Mark it up, argue about it, and adapt it to your site, because every plant has its own quirks and no generic document survives contact with a real production line unchanged. Its job is to make sure the right questions get asked early enough for the answers to matter.

Use it alongside your existing maintenance systems rather than instead of them. The checklist does not replace a CMMS or a project plan. It sits above them as a sanity check that the fundamentals, scope discipline, long lead items, controls preparation, testing and handback, are actually covered.

Shutdown Support Planning: How to Minimise Production Loss During Scheduled Outages

Scheduled shutdown periods are one of the few windows in an FMCG plant’s calendar where major maintenance, upgrades, and electrical work can be performed without the constant pressure of an active production schedule running alongside it. They are also high stakes events, since a shutdown that overruns its planned duration delays production restart, and the production volume lost during an extended shutdown can quickly outweigh whatever cost was saved by trying to compress the shutdown scope or budget in the first place.

Why shutdowns commonly overrun

Shutdown overruns rarely come from a single dramatic failure. More often, they accumulate from a combination of underscoped work, where the actual condition of equipment once opened up reveals more required work than the original plan anticipated, poor sequencing between trades, where electrical, mechanical, and other contractors end up waiting on each other rather than working efficiently in parallel, and inadequate parts and materials planning, where a required component is discovered to be needed only once the shutdown is already underway, creating a delay while it is sourced.

Scoping the shutdown accurately

Accurate scoping starts well before the shutdown date, with a structured pre shutdown inspection of the equipment scheduled for work, to identify the actual condition and required scope rather than relying solely on the assumption that planned maintenance intervals translate directly into a fixed, predictable amount of work each time. Equipment that has shown developing issues in the preceding months, flagged through proactive electrical audits or condition monitoring, should be specifically scoped into the shutdown plan with contingency time allocated, since these are the items most likely to reveal additional required work once opened up.

Sequencing for parallel work

A shutdown plan that sequences electrical and mechanical work as a simple linear list, rather than mapping genuine dependencies between tasks, almost always wastes available time. Effective shutdown planning identifies which tasks can genuinely run in parallel across different trades and which have a true dependency, for example mechanical disassembly that must complete before an electrical technician can safely access a control panel, versus electrical and mechanical work on entirely separate parts of the line that have no actual dependency and could proceed simultaneously with the right trade resourcing in place. Having a single engineering partner capable of coordinating both mechanical and electrical work, rather than managing separate contractors with no shared visibility of the overall schedule, materially reduces this sequencing risk.

Parts and materials readiness

Nothing stalls a shutdown faster than discovering a required part is not on site once the relevant equipment is already disassembled. A disciplined shutdown plan confirms parts availability, ordering and receiving anything required well ahead of the shutdown date, including spares for components likely to be replaced based on the pre shutdown inspection findings, and ideally holding contingency stock for components with a meaningful chance of needing replacement based on observed condition, even if final confirmation only happens once the equipment is opened up during the shutdown itself.

Safety and compliance work during shutdowns

Shutdown periods are also a natural opportunity to complete machine safety upgrades, risk assessment remediation, and safety system corrective actions identified through prior audits, since this work often requires equipment to be offline in any case. Bundling safety remediation into the same shutdown window as other planned maintenance avoids a separate future production stoppage solely for safety work, provided the shutdown plan has allocated adequate time and trade resourcing for it alongside the core maintenance scope.

Restart and verification

A shutdown plan should also build in adequate time for restart and verification, rather than assuming the line will simply work correctly the moment the last task is marked complete. This includes functional testing of any control system or safety work performed, verification that mechanical work has not introduced new alignment or calibration issues, and a structured restart sequence that brings the line back to full speed in a controlled manner rather than attempting an immediate jump to full production rate, which tends to surface issues in the worst possible way, mid production rather than during a controlled test.

Choosing a shutdown support partner

The most valuable trait in a shutdown support partner is the ability to coordinate multi trade work under tight time pressure, drawing on genuine familiarity with the plant’s equipment and control systems rather than encountering them for the first time during the shutdown itself. Bevtech Engineering and Automation provides shutdown support spanning electrical, mechanical, and automation work for food and beverage manufacturers, with the breadth to coordinate complex multi trade shutdown scopes under a single accountable team.
