I guess the exact cause of the problem will remain a mystery because I never got the time to check into this further. We had a lot of loose ends to tie up before the new guy would be in a good position to take over the job. I explained the situation to him and he is aware of the problem. He didn't even seem curious as to what could be causing it though. He said something like, "they're just temporary lights". I suppose he's right, temporary lighting would never cause a problem like the temporary panel plug that went up in flames!
