Frequently asked questions

The path followed by fault current as a result of a low impedance fault occurring between the phase conductor and earth is called earth fault loop. Fault current is driven round the loop by the supply voltage, the amount of current depending on the voltage of the supply and on the impedance of the loop.

The RCD is designed to trip out when the difference between the phase current and the neutral current (this is called the residual current) reaches the tripping value (or rating) of the device. The tester provides a carefully preset value of residual current depending on its setting and then measures the time lapse between the application of the current and the operation of the RCD.

RCDs rated at 30 mA or less are sometimes used to provide extra protection against electric shock. Such RCDs require a special test procedure. Set the "RCD"switch to "150 FAST". Connect the test instrument to the RCD to be tested. Make sure that the P-E and P-N wiring check lamps are lit. Press the test button to apply a test current of 150mA where the RCD should trip within 40ms.
