Re: Electrical-28 volts through ground

I have one circuit in my home that I am getting 28 vols through the bare
copper ground wire. This circuit has severallights on it. Any ideas what
the
problem could be? Even with the breaker off I am getting voltage. The
electrical panel looks ok.

A few things I would do: Check the voltage between that suspect ground wire
and the nearest water pipe. Also check the voltage between the other wires
in the switch box and the water pipe. Next I would shut each circuit
breaker off in the panel one at a time and check to see if the voltage
reading changes.

I would also go to a different part of the house on a different circuit and
check the voltage in the same manner with the circuit off.

Let us know what you find.

How many wires are in the switch box?

I'm thinking that this particular circuit may be part of a three wire
circuit. The voltage that you are reading is actually coming from the
neutral because there is a load on the other leg. By shutting off the other
circuit breaker the voltage should almost disappear. If this is the case I
recommend that you tighten all of the neutral and ground connections in the
electrical panel. There could also be a neutral connection somewhere on the
circuit that needs tightening such as a receptacle.
