Breaker amperage calculator
WebThis tool will help you calculate the load on a circuit to see if it is excessive. You can also calculate the minimum circuit breaker size for the given load. This is very useful when … WebThis calculator will let you plug some numbers in and get a quick result that you can use to properly size the system. By knowing the capacity of the transformer as well as the primary and secondary voltages, you will be able to calculate the full load capacity (in Amps) of the transformer for both the primary and secondary sides.
