I'm remodeling a room and sorting up a rat's nest of questionable electrical practices... boxes hiding in the wall, wall fixtures being used to branch circuits, etc.
At this point, all of the hard stuff is done, and I'm puzzled by what I thought was the simplest part of the job -- replacing a cracked wall outlet. After testing everything and turning the power on, the surge suppressor attached to the outlet indicates a wiring fault.
Here's what I've done so far:
- Triple-checked the connection to the socket and ground.
- Verified that the circuit is properly grounded.
- Checked other outlets terminating in the same place.
- Tested the outlet with a testing device (checks clean)
Any ideas where to go with this? I'm thinking:
- Bad surge suppressor?
- Defective outlet?
- Damage to cable in the wall?
