The 3 Best Ways to Determine Amperage of Circuit Breaker

May 29, 2020 · 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 for a noncontinuous load, which comes out the same when
