I saw it yesterday and sorry I don't have a picture for you but tell me what you think of this:
A 4" square metal box near a circuit panel. A pair of metal flex raceways with 3-4 ungrounded conductors in one, and two neutrals in the other. Both use a duplex MC connector to enter both the panel and the 4" square box. This is how the 3-4 branch circuits are fed from the panel.
What are the issues here? I recall something from school about having the hot pass through one metal circle while the neutral passes through a different one. But that was a decade ago and I haven't run into any similar situation since then.
Is it EMFs or harmonics or something like that?
