wet niche fixture in pool

[stjohnbarleycorn]

On the forming shell, there is a bonding terminal on the outside and the inside.
I am taking #8 copper to the outside, which I put (potting compound on) which in turn will be bonded to the metal wall of the in ground pool, and the rebar, pump etc., back to the panel.

I am running a #8 insulated copper conductor to the deck box from the panel. I don't have the fixture yet. Does the #8 insulated wire terminate from inside the forming shell, to the terminal strip in the deck box and then potting compound is put on the terminal in the shell, or is there a bonding wire from the fixture to that terminal in the shell, or both?

On the deck box there is an external bonding terminal, is it required to run the bare #8 to bond that to the rebar, pool grid?

thanks for any clarification on this.

Why are you running the #8 wires back to the panel?

Why are you running the #8 wires back to the panel?

Sorry, I have installed a sub panel, not a panel at the pump site, I understood that the #8 had to go back to the panel ( sub panel) continuous unless in a terminal strip, not splice, this is the insulated one, \ If you mean the bare one, that is going to the sub panel also.

thanks for the reply

also thanks for the link,

Also we are still on the 05 code, I forgot to mention that.

Pools have to be in the "top 5" subjects where "I understood" gets you in trouble, because 75% of the folks telling you have it all wrong.
Study the link and I think you will find your answers and a few flaws in your present thinking.

Neither need to be carried to the sub panel. You should read about bonding of the pool equip. and equipotential bonding

The insulated #8 goes from the fixture to the deck box and the bare #8 just bonds all the rebar,wiremesh,the water if your on the 08 code, the schell of the wet niche fixture,pump motors,heaters and any thing else that is metal that pertains to the pool or within 5' of the pool.

thanks, It took a while to download the file, I will read it and figure out where my thinking is askew.

If you are wondering about the bonding lug on the exterior of the pool light junction box- that would be used as a bond if the box was located within 5' of the water.

If the box is not within the 5', that bonding lug would not have anything attached to it.

Other than that, the insulated and potted #8 would terminate at the junction box or the sub-panel (whichever is directly connected to the niche). Some sub-panels are listed for "direct connection to underwater lights".
