I'm in the final stages of wiring as the result of relocating my inground pool equipment.
As some may recall, the original wiring was done to older / outdated code. For instance my 220v filter pump motor was (hard) wired without a ground and off a standard NON-GFCI breaker...this was done through an Intermatic timer. I have since run a separate ground conductor for the motor, also through the Intermatic timer. Also, the circuits run through the PVC conduit are now all GFCI protected.
I also moved the Deck Box by extending the 1/2" brass pipe. Here's where I have questions.
When dissembling the original Deck Box installation I noted a #8 , insulated (green) wire connected to a lug inside the Deck Box. I also noted the ground wires from the two niche lights and convenience outlet attached to a lug on the other end of the box.
Problem is the #8 wire, which fed into the Deck Box through a short piece of PVC conduit, went nowhere. It had been cut. Also noted was a #8, (green) insulated wire (same type of wire as described above) coming out from under the brick pool deck, near the niche light brass conduit, convenience outlet PVC conduit and all PVC feed/return piping. It was also cut and attached to nothing.
So, my questions are:
- Is the wire from under the brick deck from the stainless steel niche light fixture? If so, isn't the brass pipe/conduit supposed to be the bonding vehicle for the light? I believe my niche has a bonding lug accommodation (see pic)
- If not from the light is the wire from under the deck from the bonding grid of the pool structure, metal accessories etc ?
- Could the #8 wire attached to junction box lug (and goes nowhere) be the wire that is to be used to bond the motor case and other metallic equipment?
- Perhaps this wire was once connected to a ground rod (haven't looked for one but thinking it would be obvious). It seems this might be the case since the Lug for this #8 wire and the lug for the equipment grounds are basically (electrically) connected through the brass Deck Box chassis. My understanding is that the Bonding wire and equipment grounds are to be electrically separate as they serve different purposes.
Any thoughts on what I've found?
