The SmartLockPro® outlet branch circuit (OBC) combination AFCI/Switch offers advanced technology to help protect against electrical fires resulting from arc-faults plus the convenience of a single-pole switch to control the lights. This combination is ideal for kitchens, family rooms, bedrooms, dining rooms and hallways. The AFCI switch may be used for new circuits or modifications to existing circuits where a switch is the first outlet on a branch circuit. Designed to detect a wide range of potentially hazardous arc-faults resulting from damage in branch circuit wiring as well as extensions to branches such as appliances and cord sets, the OBC AFCI responds by interrupting power. This helps reduce the likelihood of the home's electrical system being an ignition source of a fire. Often unseen, arc-faults can occur anywhere in the home's electrical system including within walls, at loose electrical connections or within electrical cords accidently damaged by impinging furniture. AFCIs are now required by the National electrical Code® in many areas of the home.
