This dead front receptacle is a ground fault circuit interrupter designed for use when access to power isn't also needed. Ideal for use in spaces where ground fault protection is required around large or hard-to-move equipment, such as residential spa or hydromassage tubs and commercial kitchen appliances. The device features a convenient indicator light and accessible test/reset buttons that make trips easier to recognize and fix than with GFCI breaker alternatives. Conducts an automatic self-test every three seconds to ensure reliable protection, while also featuring the sleek, clean lines of the radiant Collection for a sophisticated look. Made exclusively for use with screwless Wall Plates from the radiant Collection, sold separately. Spec-Grade devices are engineered to meet federal specifications for use in commercial installations.
