I agree Greg- I had one guy about 2 years ago install K Copper from the niche to the deck box and he was asked to change it.
I wish the code panel would decide what that #8 wire should be called. The've waffled back and forth between grounding and bonding over the last coupla cycles. I see in the '05 it's back to being a bonding conductor.
For the interest of those who don't routinely wire pools, the raceway from the niche to the deck box on an in ground pool, is the raceway that needs to be brass or PVC. Once your past the deck box you can run regular RMC or PVC underground.
I have yet to see a job where they use brass. Must be a cost factor.
