I just installed a Hubbel GFCI socket and when I turned the circuit breaker back on the GFCI green and red led lights went on and the reset button would not stay in.
The ground wires are pigtailed and connected to the ground screw on the metal box.
The line cable leads are connected to the appropriate colored line screws on the gfci
The existing load cable pair are connected to the appropriate load screws on the gfci.
Don’t know if I have a bad GFCI or something is wrong with my my wiring.
Could another unknown GFCI device on that came circuit be causing this problem
Any ideas what might be wrong?
