How to Calculate What Breaker & Wire Size You Need …
First, you need to calculate the safe load. Remember that amp circuit breaker should be at least 125% of the load. Thus, in this case, the best breaker size = 10A X 125%= 12.5A. Note: the available breaker size ranges include 15A, 20A, 30A, 40A, 50A, etc. Therefore, in our case, a breaker size of 15A is perfect.
