Hi guys I was wondering if someone can help me with a question on my 2394 paper it says:
Why is it necessary to carry out an earth fault loop impedence test before carrying out an RCD test
My answer:
Because an earth fault loop impedance test will prove that there is a fault path to earth and without a fault path to earth an RCD cannot operate as they only operate when a live to earth or neutral to earth fault occurs.
If you could tell me if im correct or not in what im saying and if im correct do i need to elaborate a bit more
Thanks
