A GFCI receptacle is different from a conventional receptacle. It has a safety feature that will trip and shut off power within milliseconds of detecting a ground fault. This helps to protect against electrical shock. Certified: ELECTECK GFCIs are ETL/cETL certified, which assures quality and application specific electrical code compliance. Quality: Each unit of ELECTECK GFCI outlets are individually tested to close tolerances for function and safety before leaving the factory. Customers can trust ELECTECK GFCI to protect your home and family. Advanced technology: These GFCI receptacles use the latest technology to consistently ensure exact tolerances for trip threshold. This ensures safety, reliability, and eliminates false tripping. Tamper Resistant: These GFCIs feature tamper resistant outlets for where code requires, or for an extra margin of safety. Please note: Tamper resistant receptacles have a safety gate in the outlet to prevent unwanted objects being inserted. The outlet can be a bit difficult to plug into the first few times. This will become easier with multiple use. Wall Plate and Screws are Included: The included high quality wall plate and screws conveniently save you time and money on your GFCI installation.
