Federal Pacific Electric NC120N Circuit Breaker

The Federal Pacific Electric NC120N circuit breaker is a 1-pole, 20-amp, 120-volt protective device. Identified by the NC120N model, this unit is part of Federal Pacific Electric’s NC series and is configured for a single hot conductor. With a 20A rating at 120V, it is designed to interrupt current during an overcurrent event on that circuit, helping guard wiring and connected equipment from damage. The 1P, 20A, 120V specification describes the device’s electrical capacity and the scope of protection it provides for a single circuit leg in an electrical distribution setup. In practice, such breakers are used to provide branch-circuit protection where a 20-amp, 120-volt rating is required, enabling safe disconnection of power on overcurrent conditions.
