I came arcoss this in a house. From my undestanding its three phase power but only one phase is being utilised. Does this mean it's just treated as single phase. As in the the max ZE for TN-S is 0.8 or because it's 3 phase it's diferent ? I know when you normally test three phase power you test between phases but I assume you would just yest this as it was single phase as only one phase is being used. Am i right in my thinking ?
