What is your N-G voltage?

[RayDunzl]

Was catching up with grounding threads (takes a while) and remembered that some tech people told me at the time I had a high neutral-to-ground voltage differential in the office which could potentially harm the servers they were installing.

it dawned on me to measure it at home last night (takes 2 secs with a multimeter) and read 0.3V. It appears the electrical code allows for a 5% (or 6V) drop in the US. I was curious to know whether the N-G differential was a factor on the efficacy of some of the grounding equipment. Anyways, did any one measure theirs and what was it?

My Neutral to Earth voltage for all the audio/visual equipment is 60Vac. It sits behind an Equitech.


How does that fit into the worrysome scenario being discussed?

Do you have some kind of balanced power system? If so, that is normal.

That's correct.

Oops, let me respond with a belated "Thank you" and add Best Wishes for the New Year.
