When you flip the switch on a large motor, the initial surge of current can be several times higher than its running load. Calculating that starting load means accounting for locked-rotor amps, inertia of the driven equipment, and voltage drop during startup. It’s a balancing act—underestimate it and your breaker trips; overestimate and you overspend on protection.
