I have 2 pool lights and 1 spa light in my in ground pool. The conduits run in series from the farthest light back to the pool pad. The conduit to one of the junction boxes was broken, so I removed the Hayward SP0681 junction box and replaced the conduits. No problem there.
It is the bonding and grounding that is confusing me. In the junction box that I fixed, I found both the #8 bonding wires AND the light fixture ground wires were connected to the grounding terminals in the junction box. Back at the power panel, both the #8 bond wire and the #12 ground wire are connected to the grounding block (as is the bond wire from the pump / heater / pool bond wire).
I had thought that the ground and bond are supposed to be separate, so I was surprised to see them connected together in the junction box. So I checked the other two boxes. One of them had the ground and bond secured to the ground terminals, the other did not.
So, which is correct? Should the niche bond wire (that secures to the inside of the niche) and the light fixture ground wire be separate, or should they be connected together inside the junction box?
