Custom Switchboard Upgrades

Where electrical demands are bigger, more complex, and require tailored solutions, KORLEC can design and build a safe and reliable switchboard for your office, warehouse or industrial machinery.

Industrial & Custom Switchboards in Brisbane & across QLD

A custom switchboard is designed specifically for your site’s requirements. Unlike standard residential boards, it can handle:

High-load machinery or equipment
Multiple power circuits for commercial offices or workshops

 Trustindex verifies that the original source of the review is Google. Highly professional, polite, and quick to respond. They completed small but urgent job with high standard and high professionalism. If you are especially tired of electricians who are rude, overpriced, hard to communicate with, don't respond or don't even show up, KORLEC is the one you should call!

 Trustindex verifies that the original source of the review is Google. Honest, Professional, Skilled, Reliable I’ve used Korlec for several jobs now from simple power points to a very tricky 3-phase installation for an induction cooktop. While others suggested an ugly conduit up the wall, Mick and Tony found a  smarter, neater solution and did it perfectly even though it was very difficult and all with a smile. They also installed my EV charger and were, as always efficient, tidy, and incredibly friendly. What really impressed me however was their honesty. I’d had two other companies - one with a big presence - try to convince me to replace my 10 year old switchboards (over $3000 quoted) claiming they were not compliant. This is not what I had them quoting but it’s what they fixated on. It felt like a hard sell so I did some research and discovered it’s a come fear tactic used by companies. I asked Korlec when they came to quote and Xavier immediately said they were fine and my insurer confirmed it too. That’s when I knew I’d found electricians I could trust. Highly recommend Korlec.

 Trustindex verifies that the original source of the review is Google. I called several electricians before calling Korlec, and seriously, from the moment Xavier picked up the phone I knew I was in good hands! He was extremely patient (I had lots of questions) and super helpful - fabulous customer service! Xavier organised his colleague Tony to come out in a ceiling fan for me, and he turned up on time and within budget as the website says. Tony told me he loves working for Korlec, which is a great reflection on what an excellent business this is. My ceiling fan is in, and I couldn’t be happier with it!! Thanks Team Korlec! Have already recommended you to two friends who need electrical work done! 👍

Industrial & Custom Switchboard FAQ

Do you offer any guarantees?

Yes! All electrical work comes with a 12-month peace of mind workmanship warranty. If anything related to our installation needs attention within 12 months, we’ll return promptly to resolve it.

All work is completed to Australian Standards and QLD electrical compliance requirements, so you can feel confident your switchboard upgrade will perform.

What's included in a business switchboard upgrade?

A custom switchboard is engineered to suit the specific electrical load, configuration, and operational requirements of a commercial or industrial site.

This includes load calculations, circuit segregation, three-phase distribution, protection device selection (MCBs, MCCBs, RCDs), surge protection, metering, and allowance for future capacity expansion.

Do you perform load assessments beforehand?

Yes. We conduct a full site assessment, including maximum demand calculations and evaluation of existing infrastructure, to ensure the upgraded switchboard can safely handle current and projected loads. This is critical for compliance and long-term reliability.

Can you upgrade industrial three-phase switchboards?

Yes. We design and install three-phase switchboards for manufacturing, warehouses, commercial kitchens, office buildings, and high-demand facilities throughout Brisbane. Proper phase balancing and protection coordination are implemented to ensure operational efficiency and system stability.

How do you ensure compliance with a switchboard upgrade?

All commercial and industrial switchboard upgrades are completed in accordance with AS/NZS 3000 (Wiring Rules) and relevant Queensland electrical safety regulations. Upon completion, systems are tested, commissioned, and certified to meet compliance requirements for insurance and workplace safety.

Can you design a switchboard with future expansion in mind?

Absolutely. We design custom switchboards with scalability in mind, allowing capacity for additional circuits, machinery, EV chargers, or solar integration as your business grows.

Can you interate surge protection and monitoring systems?

Yes. We can incorporate surge protection devices (SPDs), RCD protection, circuit breakers, and fault monitoring systems to protect equipment and personnel. Protection systems are selected based on site risk profile, supply characteristics, and equipment sensitivity.

How is downtime managed?

Power isolation is required during installation; however, works can be staged or scheduled outside operating hours where possible. Detailed planning is undertaken to minimise disruption and ensure a safe transition from the existing board to the upgraded system.

Can custom switchboards accommodate solar, battery storage, or EV charging infrastructure?

Yes. Switchboards can be designed to integrate distributed energy resources such as solar PV systems, battery storage, and commercial EV charging stations. We ensure adequate capacity, correct protection, and compliance with grid connection requirements.

Can you upgrade sub-boards and distribution boards within large facilities?

Yes. In addition to main switchboards, we upgrade and install sub-boards and distribution boards to improve load management, circuit organisation, and system redundancy across larger commercial or industrial sites.

Need to upgrade your switchboard at home?

KORLEC provide residential switchboard upgrades from our West End base throughout the greater Brisbane area.

If you’re installing a home EV charger, solar or have an old ceramic switchboard at home, KORLEC can upgrade your home switchboard to make sure your house can handle the increased power demand.
