Wiring Rules. From professional electricians using them every day to guide installations, to the general public going about their everyday life with little consideration of their impact, the Wiring Rules are an important contributor to modern Australian life.

Developed by the committee EL , the Wiring Rules consist of two separate parts. Part one outlines fundamental safety principles that shape minimum regulatory requirements for safe electrical installation, and part two details solutions to achieve safety principles for the electrical installation work. Residential requires all final sub-circuits to be protected by a 30mA RCD, while non-residential requires all final sub-circuits up to and including 32A to be protected by a 30mA RCD and there are a number of exceptions to this that can be applied.

Hopefully no more problems. Firstly, there was an exception that allowed the electrician to forgo testing of an RCD if there was no power to the installation. If you think about it, this is crazy. This exception will be removed. So, it is now important to test that RCD to ensure it works as intended which I reckon most in the electrical trade are doing anyway. Walk away from your job knowing that the installation works as intended.

Secondly, regarding alterations, we have removed the ability to add RCD protection at the start of the additional part of the circuit this was usually done by adding a socket-outlet RCD at the beginning of the new part of the circuit. Incorporating this change will mean that the altered circuit will need to be protected by RCD at the origin of that circuit, the switchboard. Makes sense, as it is a way to ensure that the whole circuit is duly protected.

Thirdly, in respect of repairs, there is increased clarity regarding the replacement of existing lighting. To explain, if replacing existing halogen downlights, that may have been directly connected to the existing lighting circuit, with LED downlights that have a 3-pin plug for connection to the lighting circuit, the sparkie may add a plug base surface socket into the existing lighting circuit. The way it was worded would mean that this would require an RCD at the switchboard as a socket has been added , but there is now an exception to allow the repair or replacement of the light fitting and addition of plug base without needing to provide RCD protection.
