Electrical Panel Temperature Ratings. the rules apply to any equipment rated 100 a or less. why are temperature ratings important? but the temperature of a residential circuit breaker in a panel should not exceed about 140º f; where two or more heating fixtures, trace heater sets, or heating panel sets are grouped on a single branch. For equipment with termination provisions for circuits rated 100 a or less. the acceptable operating temperature of a circuit breaker is defined by ul in the ul489 standard (june 2011),. many electrical inspectors can tell you that confusion about wire temperature ratings and equipment termination temperature requirements. it is acceptable to use wire with a higher insulation rating if the ampacity is based on the wire temperature rating marked on the breaker. Conductors carry a specific temperature rating based on the type of insulation used. as the majority of circuit breakers, switches, panelboards are marked with maximum termination temperature at 75˚c, electrical designers.
