Unusual Wiring - Comments please
I was asked to change a ceiling light in a recently constructed commercial building. The unusual (and expensive) Florescent lamps used in the light were prone to frequent failure. When I took the lamp down I found the white lamp wire connected to the green (plastic insulated wire). The light didnt work when connected white to white and black to black as would be normal! Checking at the door switch we found that they used a single (2 wire with ground) bx cable from the switch box inside the door to control two lights. They used black for the feed to light one, white (marked black at the switch but not at the light) for the feed to light two, green for the neutral and the BX shield for ground. This cable went to light #one first, then the circuit carried on to the second light but with the green which had been used for neutral from the switch box connected to the white and the white from the second switch connected to black to feed light #two. How the green (or Bare) to the second light was connected I'm not 100% sure but it was probably connected to metalwork at both ends.
The whole several million dollar building was just completed by a GC so well regarded in this town that "he inspects his own work" (apparently didnt get an electrical inspection). The occupants have complained about frequent failures of computers and other electronics even when connected to good surge protectors.
My questions- Can anyone think of a legal justification for using a ground wire this way?
And- How should the owner proceed with the situation (building is less than a year old)?
