Testing the ground circuit


I have just wired in a 120 v outlet. The wires were in place from a prior application and there is nothing else on this electrical line. The circuit breaker is in the off position. I discovered that the circuit neutral (white wire) and the ground wire (bare wire that gets tied to green screw) are electrically connected. I have not turned the circuit breaker on. Is this normal?

Yes, this is normal for then to be connected together in the panel.

did you test the resistance of these wires to each other, or do you see aphysical connection in the receptacle box. they are connected in you main panel, not again.

Typically there will be 1/4 ohm between these two, depending on your wire gauge. You may be able read this low on some meters. You may need to turn all house power off to get usable readings.

Ideal makes a tester for finding "bootleg" connections between these two wires.
