I am working on a fire truck with a headlight problem. It is equipped with auto resetting circuit breakers. The headlight and taillights are intermittently going off and on when the circuit breaker trips, then resets. They are new 20 amp circuit breakers. The amp draw is 9 amps on the taillight circuit and 11 amps on the headlight circuit with the high beams on. The circuit breakers are getting really hot (160 degrees) but not tripping. This amp draw does not seem excessive so why are the circuit breakers so hot?
