Patented, advanced technology dead-face safety design blocks power at the GFCI receptacle face and all downstream connected receptacles if the GFCI is improperly wired with a line-load reversal. The GFCI cannot be reset unless it is correctly wired from the line side. Lockout action prevents reset if GFCI protection has been compromised, reducing the possibility of end-users incorrectly assuming that a reset GFCI is providing protection when it is not. Advanced electronics design provides superior resistance to electrical surges and over-voltages. Patented bridge contact provides individual set of contacts for GFCI receptacle face and downstream receptacles. Matching TEST and RESET buttons.
