Well it looks like my electrician screwed up. He did not instal a bond wire inside the conduit. The inspector didn't say anything about it, but I asked the electrician if I needed one and he said no, it is bonded externally. So now I have a pool full of water and no bond inside the conduit to the j-box. Potting one now would be a trick, plus he used 1/2 inch conduit so there is no room for one anyway.
The niches I have are PVC and and have the bond lug that goes through the housing. The fixture screws into a tab that is connected to the bonding lug. The lug is connected to the bonding grid externally so the fixture is bonded. The code required bond wire inside the conduit is insulated and should be fully potted so it is not tied electrically to the inside of the niche or the conduit other than through the exposed portion of the fixture so it seems that the purpose of this bond wire is to tie the j-box base into the bonding grid. If that's the case, wouldn't a #8 wire connected to the metal portion of the j-box and the bond grid serve the same purpose? I'm not thrilled about the idea of draining 15,000 gallons out of my pool and running new conduit so I hope I can find another solution.
