RCBO Installation Sydney

An RCBO combines the functions of a safety switch (RCD) and a circuit breaker (MCB) into a single device, delivering both earth-leakage and overload protection on each individual circuit. Sydney Power Group (SPG) installs RCBOs across Sydney for the highest standard of switchboard protection.

SPG is a Level 2 ASP electrician authorised across Ausgrid, Endeavour Energy and Essential Energy, so we can fit RCBOs and, where a job also touches the main switch, consumer mains or metering, complete that Level 2 work too.

Why Choose RCBOs

With shared safety switches, one earth fault can trip several circuits at once, plunging half the house into darkness. RCBOs solve this by protecting each circuit independently, so a fault on the dishwasher does not knock out the lights or the fridge.

This granular protection makes fault-finding faster and keeps essential circuits running, which is especially valuable for home offices, medical equipment and food storage.

A Neat, Modern Board

RCBOs mount on standard DIN rail, letting us build a clean, well-organised board with a clear legend showing exactly what each device protects. We test every RCBO with an RCD tester to verify trip performance and record results with your certificate of compliance.

RCBO installation pairs naturally with a full switchboard upgrade or ceramic fuse replacement if your board is still running old fuses.

Upgrade To Per-Circuit Protection

SPG installs RCBOs across Greater Sydney and NSW, and as a Level 2 ASP on all three networks we can integrate any required supply or metering work into the same job. Not sure whether you need RCDs or RCBOs? See our safety switch installation page.
