  • The 3 Best Ways to Determine Amperage of Circuit Breaker

    May 06 2021  Multiply the amperage by 0.8. For everyday use it s a good idea to expose the breaker to a maximum of 80 of the rated amperage. It s fine to exceed this for short periods of time but continuous current above this amount could cause enough heat to trip the breaker. Breakers should be sized at 125 for a continuous load and 100 for a non continuous load
