My pool builder has basically abandoned the job at 95% complete (fixing all the screw ups is going to cost him much more than I owe) and I am trying to get it finished myself. The lights (spa and pool, both are intellibrite color, 120v) were installed, wired to the J-box and then onto the control/breaker panel but never connected to the breaker. In the mean time the j-box starts dripping and then water running out of it draining my spa. He mounted it 10" below the spa water line (one of his many screw ups). So, my plan is to raise it 8" above the spa level and finish. I pulled the light out of the spa hoping to find 3-5 feet of cord but of course, he left all of about 15" so I will be close on even being able to raise it high enough. In looking inside I am trying to understand how it is supposed to be wired. There is a thick black wire with 2 wires for power and 1 ground. There is also a separate thick green wire that looks to be tied to the wet niche. I gather this is for bonding and should be tied to the niche. Where it is tied, or appears to be tied to the niche, it is covered with a big blob of what looks to be roofing tar. I guess my questions are - What is this blob of tar type substance and should it be there (I want to remove it and inspect the connection, should it be replaced)? Are my assumptions correct on the wires and the green should tie to the brass lug in the light J-box? Should there also be a bonding wire run to that J-box and tied to that lug (if not, I don't see what tying them to that lug does, it looks to be in plastic)? And, is there any way to lengthen the power wires so I can raise it to the level needed? I fear I may have to buy 2 new light units with long enough cords and at $500 per I'm not too excited about that. I should add, I will have an electrician do the actual electrical work but am trying to figure out exactly what that will be. Any input would be appreciated. Thanks!
