Hotline 1,
90 percent of the pools in my area use use brass from the light to juction box. It may cost a little more, but saves a lot of time. If PVC is used the ground has to be potted & inspected before the pool can be filled. With the brass the pool can be completed without losing time waiting for inspection. I no nothing about duct seal in pipe.

Does anyone know of any place on the web that has a picture of the inside of a Deck Box with the Brass bottom? I'd like to post a picture here to show the difference from the PVC one here and illustrate how the internal strain relief clamp is configured in it.

I thought this box was non-metallic at first too but don't think it is. The 4 ground screws would be useless and the metal raceway connecting to the box would be a violation. I'm guessing it's just painted gray. The metal boxes used in my area have a brass base without any type of coating with either a brass or non-metallic cover. The cord grip is in the box is similar to a 2-screw NM connector.

Curt,

Yes, the boxes you describe are what I've been used to seeing too.

You've got me wondering on this box here now ....... John?

The problem with PVC deck boxes is support. How are PVC deck boxes supported?

I thought the bottom was brass.
Maybe the one shown is plastic-covered brass.
