At Lai Switchboards we pride ourselves on our ability to custom build our main switchboards from the ground up. We can custom design switchboards from single line diagrams, or base the design on information we gather from our clients.

Our strength lies in paying particular attention to project requirements and working closely with our customers, providing complete transparency of production during quotation, design and construction.

Because we custom build our switchboards, we can source and install various brands of switchgear and control gear, enhancing cost effectiveness when and if a specific brand is requested by a customer.

We design and manufacture main switchboards up to 7000 amps with a fault withstand up to 120kA for 1 second and any form of segregation to AS3439.
