An RCD is designed to protect against the risks of electrocution and fire caused by earth faults.  For example, if a faulty appliance overheats causing the electric current to flow to earth. It does not offer complete protection and in certain circumstances may only operate after a fire has already started in your appliance.

You should test all fixed and socket RCDs about every three months. Manufacturers recommend that portable RCDs are tested every time you use them.
