If you hesitate to use NM cable, notice that ENT (smurf tube) is also now acceptable on the inside of the building.

Gentlemen:
Also keep in mind the conductors within the conduit (PVC) that's in the trench, has to have a "W" in the insulation. (THWN)

Bill,
That is correct and that is why I stated the fact that a motor CAN be wired in NMC wire inside a house, but a panel or pool light can not. Too many times contractors get that confused. Pool wirng is not that difficult if everyone did it correctly. However too many people try to cut corners and get stuck on the installation because of it.

I have done many pool installs in the South Jersey area and I usually run inside the house with 12/2MC(I make it a personal policy to generally not use BX for any thing these days {I know that there is many schools of thought regarding this, but that is a whole other post}), then I transition to plastic pipe through the back of a 1900 box/LB fitting on the exterior wall leading down into the trench. I have not had any inspection problems and I usually do splice the insulated ground in the aforementioned 1900 box.
