Elevator light

[Bbaehre91]

So I’m looking at an elevator. Someone was trying to replace the light inside the elevator. The shorted it out and blew the fuse. They replaced it and still not working. They called me now and it’s a little out of my element. There is no power to the light still with a good fuse installed. All the wires in the fixture read continuity to eachother as if they are all connected somehow. There is a relay board at the top of the elevator shaft that is completely unlabeled. I’m curious if it would have shorted out bad enough it would have fried the relay somehow and that is making it read continuity through everything. It was completely fine before they shorted it.

Sounds like a job for the elevator company.

If the fuse was properly sized it should have protected any electronics but anything is possible. Is.there an elevator machine room? Often there is a fused disconnect in the EMR for the cab lights, maybe that fuse blew.

There is a sub panel for the disconnect on a wall right outside the elevator. The fuse that blew was a 20 amp. My only thinking now is that somehow it blew the relay. Unfortunately there’s no labeling done in the relay box and there’s like 40 relays

I agree with Hal, I would turn this over to the elevator company
