Three Phase Main Switchboards
Three phase main switchboards for residential and light-commercial installations — including our popular fully pre-wired 3 phase kit with meter box, SPD/MPD fuses, main switch, RCBO protection and metering pre-wire, ready to mount and terminate.
Pre-wired to save hours on site
Our pre-wired 3 phase kits arrive as a complete panel-and-box assembly: 3x 80A SPD/MPD fuses, three phase main switch, RCBO safety switch, sub-board enclosure, metering pre-wire and earth bond — labelled and test-tagged. Mount it, terminate the mains, and you're done.
Three phase for modern loads
EV chargers, ducted air conditioning, pools and granny flats are pushing more homes to three phase supply. A properly configured 3 phase board gives the headroom for these loads plus provision for future metering changes.
