Circuit Overcurrent Protection

Overcurrent devices protect the circuit conductors and conductor insulation from overheating. They also limit the damage associated with overheating and faults in downstream equipment. Fuses performed this function during the first days of electrical distribution, but circuit breakers of ever increasing sophistication have been available since the early 1900s. This paper focuses on circuit breakers and describes the wide variety of available devices. The emphasis is on low-voltage residential, industrial and commercial applications where the circuit voltages range from 120 volts through 600 volts. This is the area that is commonly encountered by electrical inspectors.

Arc-Fault Circuit Interrupters

The objective of this paper is to increase inspector-awareness of arc-fault circuit interrupters. The significance of AFCIs is discussed in the introduction, and this is followed by a description of recent changes associated with the standard, with the National Electrical Code, and with the availability and application of the technology. Here there is a general discussion of AFCI availability, followed by a detailed description of the Cutler-Hammer line of residential miniature circuit breakers that incorporate branch/feeder AFCIs and a brief description of the technology involved.
