A transfer switch safely connects your generator to your building's wiring. An automatic transfer switch (ATS) detects a power failure, starts the generator and moves the load across, then switches back when the mains returns. We supply automatic and manual transfer switches from Generac, MAXiATS, GTEC, FG Wilson and Kipor, and can supply and install the complete generator and ATS system.

Automatic and manual transfer switches

An automatic transfer switch makes a standby system hands-free. It starts the generator and transfers the load without anyone on site. A manual transfer or changeover switch costs less: you start the generator and switch over yourself, which suits portable generators and occasional use.

Choosing the right transfer switch

The switch has to match your supply and generator: the current rating in amps, single or three-phase, and whether the generator supports auto start. Our range runs from home-scale switches to industrial transfer panels for commercial and critical sites. Send us your generator model and switchboard details and we'll recommend the right switch.

Installation

A transfer switch must be installed by a licensed electrician. We can handle supply, installation, commissioning and testing as one job, generator included. Book an installation or call 1300 622 436.
