A garage consumer unit is used to feed up fewer load circuits (generally 2-5 units). Another way to protect circuits under the 17th Edition IET Wiring Regulations is by fitting Residual Current Circuit Breaker With Overload (RCBOs) to every circuit, and although this is more costly than the RCD+MCB's option, it means any fault condition on a circuit trips only that circuit's RCBO, so the search for the fault is narrowed down from the start.

The load points and circuits on the RCD + MCB side can be connected via three wires i.e. This will protect all circuits but if the RCD trips, so do all circuits. It May Be Used To Fit Up To Three New Sentry MCBs. You may now restore back the power supply by turning ON the main switch or related circuit breaker in the consumer unit and test if it is working perfectly. Search stock photos by tags. Since the introduction of (BS 7671:2008 incorporating amendment no 1: 2011) 17th Edition IET Wiring Regulations, consumer units in the UK must provide RCD protection to all cables embedded in walls excepting high integrity circuits such as those for burglar alarms or smoke alarms.
