Safety switch laws and requirements

Safety switch 3

What does the law say?

All domestic installations must have as a minimum, one safety switch in the electrical switchboard, also called a RCD (residual current device). The safety switch detects leakage of current to earth and interrupts the supply to power points. The drawing shows you where the switch is installed.

Of course there can be individual safety switches mounted in power points. The advantage is that the rest of the installation is not interrupted. Also RCDs can be mounted on power point extension boards.

All new homes must have safety switches protecting all power points. Before any electrical rewiring can be carried out on a home, a safety switch must be installed.

The laws vary slightly from state to state. See below for details.
