Schneider Electric QO115CAFI Square D Qo Single Pole 15 Amp Combination Arc Fault Pigtail Circuit Breaker, Black

In 2015, the Canadian Electrical Code required the use of Combination Arc Fault Circuit Interrupters (CAFCIs) in each branch circuit in the home suppling 125V receptacles rated 20A or less (except in the kitchen/bathrooms and sump pump). The CAFCI breaker effectively stops the flow of current before an electrical fire from dangerous arcing can start. Typical causes of dangerous arc faults in a residence are: cord insulation damage from furniture, drywall screw piercing insulation, punctured cable by nail or staple. A standard feature in all Square D QO CAFCI circuit breakers is the TIME SAVER diagnostics test that assists in identifying the type of fault that last occurred in a circuit. It saves money by reducing troubleshooting time, simple to use and requires no tools. For new construction or new wiring in the house.
