20 amp GFCI circuit breaker


Can temperature be a factor in tripping the breaker?

No, something else is tripping it, if that's really the question.

In cooler outside temperatures the breaker never trips, but as warmer weather occurs it begins to do so. The warmer the outside temp the more frequently it trips. The breaker only services the lights and outlet in two bedrooms.

More likely that you have a moisture condition at 1 of the outlets( receptacle or light fixture). When the temperature rises the humidity does also causing a high resistance leakage to ground.

Being a layperson, can I determine that or do I need to call a professional?

Even a loose or poor connection can also cause it to trip.

Depends on your comfort level and your mechanical abilities. Only you can make that determination.

Yeah, but wouldn't you expect it to trip as well when the weather (air temp) isn't warm?

I'm fairly comfortable and mechanically capable. Just need to know what to look for. I gather I will need to open each of the outlets and I suspect I will need to wait to do when the warm air temps return.

Open all appearances of the circuit and look for loose connection. If any wires are backs-stabbed, connect directly to the screws or pig tail them. Look for signs of moisture, green corrosion.

Open the breaker panel and make sure the breaker & neutral connection are tight (turn off power when oping panel or pulling out switches and receptacles).
