What temperature is too hot for a circuit breaker?

2021-6-13 · All circuit breakers generate a small amount of heat and may be several degrees warmer than surrounding surfaces. But the temperature of a residential circuit breaker in a panel should not exceed about 140º F; or, on hot days, it''s better to only call it out when the temperature difference between the breaker and surrounding surface exceeds 50º F.
