Aug 03, 2018First, find the breaker that correlates to the electrical device you are using (This is normally either a 15 amp or 20 amp circuit). Multiply the amperage by 0.8. This is because a circuit breaker should never exceed 80% of its max amperage. Not doing this could leave room for calculation errors, or even worse – electrical fires!
