How would you answer this Q:
A final circuit is installed using single core pvc insulated cables enclosed in steel conduit. The conduit is used as the cpc. An earth fault loop impedance test identifies that the max permissable Zs has been exceeded. describe:
A) 3 possible faults that may cause the high reading
B) One test that could be performed to verify the reading.
Just blown my mind on so many revision Q's today that my brain has gone into melt down and I have been looking at this Q for so long I have gone blank.
