A POTENTIAL APPLICATION OF ARC FAULT CIRCUIT INTERRUPTERS IN SHIP ELECTRIC SYSTEMS

The arc-fault circuit interrupter (AFCI) is emerging as a new device in the US National Electrical Code (NEC) and in residential installations to enhance electrical safety. New technology generally fosters questions and concerns about the workings and application of the technology and this article will address some of the most frequently asked questions surrounding AFCI: • How does the AFCI work? and, • What is the state of the potential application of AFCIs in ship electric systems? This article addressees both questions.
