Came here hoping someone could clear up a question about a grounding pad that connects to the ground receptacle of a house outlet.
I was concerned it might be unsafe in a ground fault, so did a continuity test to determine if the pad and wire running from the outlet to it were conductive. Turned out it has a 100K resistor in the wire, apparently to reduce the possibility of electrocution in a fault.
Two questions:
Is it indeed safe?
And if the resistor prevents AC from flowing in a fault, doesn't it also impede its effectiveness as a ground to earth?
My brain tells me if I wanted to create a good ground I wouldn't want to build a ground wire with a lot of resistance in it.
