Frequently asked questions


What is a safety switch and why should I install one?

Safety switches are your insurance against electric shock. They are designed to prevent injury or death.

They monitor the flow of electricity through a circuit. They automatically shut off the electricity supply when current is detected leaking from faulty switches, wiring or electrical appliances. This stops the chance of current flowing to earth, through a person, electrocuting them. Installing a safety switch is an inexpensive safety measure that protects everyone.

The law says all homes built since 1992 must have safety switches installed on power circuits. They are not an optional extra! If you are building a new home, you must have a safety switch installed on both power and lighting circuits.
