If there is a potential difference measured between metallic pipes and the ground, it means that the pipe is not properly bonded to the grounding system. See FPN No. You're seeing voltage drop on the neutral, which since a neutral starts at 0V, tends to lift the neutral's voltage up a volt or two. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current. equal to the voltage drop of the neutral conductor in accordance with but it could also be that voltage going through a light and trying to return to the electrical panel on the white, but not being able to get there due to an open neutral that is touching the bare metal of the can light or a ground wire.
