[QUOTE="Emmadas, post: 535137, member: 35717"] Hi All, I was looking at the 'Learn Electrics' video on youtube about Zs and I was confused about the fault currents that flow down the earth wire to disconnect the circuit breaker. The video says that in a fault 700amps flows down the earth wire, but how is that possible when the csa of the earth wire allows only a certain amount of current to flow through it, can someone help me to understand?
