The Effects of Arcing Ground Faults on Low-Voltage System Design

Abstract

Recurring reports of arcing ground fault burndowns have generated a considerable amount of interest in the subject on the part of those individuals who are responsible for the design of power systems. In fact the interest is so widespread that as one consequence, article 230-95 of the 1972 edition of the National Electrical Code requires that service entrance devices of specific types be equipped with additional ground fault protection.
