ELEGRP’s ground fault circuit interrupter (GFCI) outlet provides continuous protection from ground faults during its whole life period. The GFCI receptacles conduct an auto-monitor function self-test every five seconds exceeding UL 943 requirementsfor a frequency of 59 hours. Ultra-compact design leaves more space for other wiring devices for easier and quicker installation in electrical boxes. Miswire protection interrupts power in an event that the GFCI receptacle is miswired by interposing line and load branch circuit supply wiring. The GFCI receptacle will deny power to receptacle face and downstream. Automatic shutter system prevents young children from inserting unwanted objects into the outlets.
