I guess I'm still confused. I thought that the #12 ground conductor that came with the light went straight back to the equipment ground. The insulated #8 from the bonding lug inside the wet niche is terminated on a screw in the jbox. I must also terminate the #12 in the j box on another lug, then from there goes back to the ground bar in the circuit panel? How about the #8 insulated ground. Does it just terminate in the j box or does that then proceed back to the circuit panel. Thanks. Sorry about my confusion.
