Well, I would expect that your tingle was from coupling with one or more of the energized wires in the pipe. Were you measuring less between the conductors than you were between each conductor to ground? I would expect that to be the case. Is it practical to LOTO the other ckts that go through the same pipe and about how long a run is it?

On second thought, I would think that the Neutral to Earth might show the highest reading, since it's connected on one end. It would be almost like you're touching the output of an auto transformer.
