[QUOTE="Shakey, post: 22264, member: 1554"] additionally the rule of thumb allows for the fact that when measuring the Zs the circuit is cold, and the resistance will be 'artificially' low, and pre-supposes that the circuit will be at normal operating temperatue when the fault happens of course it is pretty much irrelevent unfer the 17th edition anyway, as most circuits need only be lower than 1667 ohms (can opened, worms everywhere) but of course i am not a real electrician so i am only guessing:^O [/QUOTE]
