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?
