Safety Switches.

For some time now it has been mandatory for electrical power circuits and lighting circuits to be on residual current devices. The purpose of the RCDs is to interrupt the flow of electricity down to earth when there is a difference of less than 03.mA in the flow of electricity. I’ve found the best value RCDs are Clipsal, HPM or NHP. There are cheaper options but I have lost count of how many times I have replaced these that have been installed by other electricians. Don’t risk it. Use a quality brand to protect you and your family.
