The 122 gauge cable for this circuit includes 2 conductors and 1 ground. In this four wire afci wiring diagram two lines as l1 and l2 has been connected to the input terminals of afci breaker and the builtin white is connected to the neutral busbar in the mains supply.
How To Wire An Afci Breaker Arc Fault Circuit Interrupter Wiring
Afci breaker wiring diagram. With a standard circuit breaker there is only one wire connected to the breakerthe circuits hot wire. The light green arrow points to the afci device youll notice that it is much longer than conventional circuit breakers in the panel. Arc fault circuit interrupter breakers prevent fires by sensing when an electrical arc is about to occur and instantly disconnecting the damaged circuit before the arc builds enough heat to catch firestandard circuit breakers dont always trip in these instances because standard breakers are designed to respond to a sustained amount of heat not a quick surge. Each afci breaker involves three electrical connections. Our afci photo at left illustrates a square d 20a afci breaker during installation in the electrical panel. In today post we will show the different wiring diagrams for afci combination switch with outlets light switches and other components and devices to protect the residential areas from unintentional arc fires.
