Troubleshooting a couple light fixtures that had the lamp holders blown out in an office building and found that the voltage at the fixtures was 96V to ground/neutral. Checked voltage at the breaker and got 117V. The run is only about 75 feet but it does splice at a couple boxes before the fixtures that burned out. Thinking that there must be a bad splice somewhere but I am not the buildings electrical vendor so I had to bow out before I dug to deep. Still would like to know what the likely problem for the voltage drop is.

Thanks in advance!

Yes three phase 208/120. Can you define neutral issue? My first guess was a loose neutral in one of the boxes....

Start at the panel and work your way ot. TURN OFF ALL LOADS, what you have is a potential equipment destroyer and fire hazard.

Yes, but not all. If theres no kind of transformer or ballast in between, if there is it also has to be compatible with a dimmer. So in short most are but not all.
