Web29 aug. 2024 · Overcurrent protection is a safety mechanism that prevents currents above the acceptable current rating of the circuit or equipment. Overcurrent protection is generally achieved with magnetic circuit breakers or fuses and operates instantaneously. Overcurrent instances can occur due to short circuit events or an overload event. WebThe National Electrical Code (NEC) in Section 430-32 (a) (1) allows a motor with a service factor of 1.15 to use overload protection of 125 percent. This allows the motor to operate at up to 15 percent above its normal rating without causing the overload protection to trip. scfhs profile numbers online
