Thanks for the replies. Yes I used a digital meter. Lamplighter, I think you may have the answer. It may have been a cap discharge. I forgot to say that after I checked it a few times, that finally I got nothing. I thought it strange that all of a sudden after all that checking it stopped. I'll check it tomorrow to see what it went to. The breakers wern't labeled correctly, and there had been some
unauthorized "tampering" with the panel before I got there. I could tell from the way they brought a piece of 3/4" pvc into the panel. Instead of using an "LB" to come in the side of the panel, they used 2 90's, ( one to go under the panel, then back up in the panel) I had to change it. I didn't want the inspector to think I did it [Linked Image] And by the way, when I was putting the new breakers in, I noticed that they had a 50 amp. breaker on this # 10 wire that I had the voltage on. At first I thought they just over fused the wire, then I determined that it might be coming from an a/c unit somewhere, in which case you'll allowed to overfuse the wire. This may explain that it was a discharge from one of the capacitors, though I've never had it to happen to me before. Thanks for the input. I'll check it tomorrow. Steve
