The Radiant 20A Tamper Resistant Self-Test GFCI Receptacle from Legrand Adorne is made from durable, high-impact, resistant thermoplastic and metal. Your receptacle goes above and beyond by conducting a self-test every 3 seconds, offering you peace of mind against ground-fault occurrences. Should the need arise, the indicator light will flash if the receptacle fails. Innovative SafeLock protection will cut off power to the outlet to prevent further issues if critical components are damaged.
