I mentioned on Saturday that we lost electricity in our computer room Friday night. Even after unplugging everything from the outlets the circuit breaker kept tripping.
Betsy’s creativity with extension cords kept us online, but we knew we had to get the problem fixed. We just hoped the repair wouldn’t be too extensive or too expensive.
The circuit that failed is strange — it includes the outlets and ceiling light in the computer room, a mirror light in a bath room, and a lamppost light in the front yard. I suspected that the problem might be related to the front yard light which hadn’t worked for a couple of years.
When the electrician arrived he quickly determined that we had a dead short someplace along the circuit. The wiring in the lamppost was properly tied off and insulated. It was possible the problem could be along the buried wire leading to the lamppost or in the walls of the room. How could we find it? While we were talking the electrician pointed to a switch and asked what it was. We had to think for a moment but replied that it was a switch to the yard light.
The switch position indicated that the light was off, but the electrician tested it and the switch was on! He flipped the switch, reset the circuit breaker, and we had power in the computer room!
Duh! To prevent a recurrence we had the electrician completely disable the switch. We’ll put a solar light on the lamppost.
