RCD Safety Switch Testing
RCD Safety Switch Testing helps to provide electrical safety by detecting any interruption to the electrical circuit caused by a current leakage to earth.
Safety Switches are designed to isolate the flow of electricity of a circuit when detecting a leakage to earth within a prescribed time and current. They will shut the power off quickly and substantially reduce the risk of electric shock or electrocution.
RCD Safety Switches are generally installed in Electrical Distribution Boards and Sub Boards. There are also some GPOs (power points) which have built in RCD’s and there are portable power boards with built in RCD’s.
All RCD Safety Switches are required to be regularly tested at intervals noted in table 4, AS3760:2010
Testing Safety Switches is carried out by simulating a current leakage to earth and recording the time for the RCD to shut down isolating the circuit and the amount of current required.
RCD Safety Switches are a very important device in helping provide electrical safety and must be tested regularly to ensure their correct operation.
