What circuit breaker will reset automatically?
Circuit breakers come in 3 types: Type 1 are auto resettable, and once tripped, will attempt to reset the circuit, or ‘cycle’, as the internal elements of the breaker cool down. Type 2 (trip and hold) are called modified reset, and will remain tripped until the power is removed from the breaker.

What’s the life expectancy of a circuit breaker?
Modern circuit breakers have a life expectancy of 15 to 20 years. While some circuit breakers can last longer, arc fault (AFCI) and ground fault (GFCI) type breakers have a shorter 10- to 15-year life because the internal sensors wear out quicker than the breaker itself.
