Safety Switches (Residual Current Devices)
Updated: Mar 3, 2019
Safety Switches are essential electrical devices that provide protection against electrocution in your home or business. They monitor the flow of current through the circuit and will trip when a fault is detected.
What is a safety switch?
Residual Current Devices, commonly known as a 'Safety Switch' are electrical devices installed on a circuit for protection against electrocution and other electrical faults. They come in different shapes and sizes depending on the circuit it is protecting. In January 2019 it became mandatory to have safety switches installed on every sub circuit up to 32 Amps.
How do they work?
A Safety Switch monitors the flow of current through the Active and Neutral conductors in a circuit at all times ensuring they are the same. Once a current change is detected, the safety switch will shut off, disconnecting the supply within 3 milliseconds.
Why install a safety switch?
Not only do safety switches provide protection against electrocution, they can protect against fires by identifying a fault such as a hot joint before its too late. Having a safety switch installed ensures you have the best possible protection, it can save you thousands in repairs and will also possibly save your life in the event of a serious fault.
