I turned off each circuit breaker in my electrical panel to understand which switches controlled which devices, and now one of them immediately goes to the middle (tripped?) position when I turn it back on.
Last week, I installed a doorbell camera. I thought I had turned off the breaker before beginning to work, but had flipped the wrong breaker switch. I figured that out when I connected the cabling to the doorbell and saw sparks. Since it was the last wire, I just connected it and completed the install. The doorbell worked correctly.
I wanted to work on the doorbell again today, and thought I'd start by correctly identifying which breaker controlled the doorbell to safely power it off before beginning work.
I turned off the breaker switches 1 by 1 until the doorbell lost power. It was one of the last switches in the second (outdoor) panel, so almost every switch was in the off state at this point. When I went to turn on the other switches, a separate switch controlling a circuit in the garage would immediately return to the tripped (middle) position when I turned it off and back on. The circuit with the doorbell works correctly.
What might have caused this, and how can I get the breaker switch to turn back on?
- Turn the breaker switch all of the way off, then on again.
- Unplug everything I can identify on that circuit, attempt to turn on the breaker again.
- Apply pressure to the switch as described in Circuit breaker won't turn back on after being turned off (not tripped)
