Industrial Switchboards Limited
ISL Icon

Big switchboards, built in New Zealand 
and delivered to Queensland.

Custom-built to your specification, tested before it ships, and backed by a team that picks up the phone.
Built your way

Built your way


We build what you need, not what our process allows. If your project calls for a particular layout, rating or arrangement, we design around it.

Your choice of switchgear


Many manufacturers are tied to a single supplier. We’re not. We build with a range of switchgear and metalwork, so you get the right equipment for the job.
Faster than you’d expect

Built your way


Australian builders often have long lead times. Our builds are quicker and more flexible, so shipping across the Tasman usually costs you no time, and often saves it.
Built in Hamilton, NZ | Up to 6300A, 100kA | Powering power stations, data centres and dairy factories

How it works, from enquiry to installation

From first conversation to commissioning, in four steps.
comment

1. Specify and design
Every good switchboard starts with a conversation. We learn about your requirements, your loads and your compliance needs. Then we prepare a general arrangement drawing and send it with project pricing and lead times. Nothing gets built until you’ve approved it.

2. Build and test
Your switchboard is built by our team in New Zealand, by people who take pride in the work. Before it leaves, we carry out Factory Acceptance Testing. You can attend in person or join by Teams, and you receive the results.

3. Pack and ship
We pack it carefully and freight it across the Tasman. Certificates and as-built drawings travel with it, so everything you need is in the container when it arrives.

4. Install and support
Your team handles the install. Our engineers are a phone or video call away to talk through drawings, answer questions and help you reach commissioning with confidence.

Packaging, shipping and insurance are quoted upfront with your project pricing

Frequently Asked Questions

Packaging, shipping and insurance are quoted at the same time as your project pricing, so there are no surprises later.
Not usually. Australian builders often have long lead times, so building in New Zealand is no slower, and frequently faster.
A full Factory Acceptance Test is completed in New Zealand before shipping, and you can watch it in person or over Teams. Every new build also comes with a one-year warranty.
It isn’t an issue. We’re available 24/7.
This is arranged case by case. Usually your installers handle it, and we’re there to support them.

Proof it works

proof it works

Laminex’s 40-year-old switchboard couldn’t cope with planned plant expansion and a new solar installation. ISL designed and built a replacement and delivered it on time, to match the completion of the solar installation. This was despite difficulty sourcing parts during the COVID-19 lockdowns. According to the plant manager, it has run without issues or modifications since installation.
