WebThe Circuit Breaker calculator tool follows the principle that a calculation is made to determine the minimum fault current to operate a circuit breaker instantaneously. It will allow for results from low voltage air circuit breakers (ACB), moulded case circuit breakers (MCCB) and miniature circuit breakers (MCB). WebTo determine the electrical load, you must divide the total load by 240 volts. For phase load, you must multiply the voltage x route three x power factor If applicable for 3 phase power. Aim for a maximum of 250 volts. To calculate the electrical load of a panel, you must know the voltage of each circuit breaker.
