While I don't currently have it in front of me, I could have sworn that I read something to this effect in 680:
"The nonmetallic conduit must be buried a minimum of 12” deep if 120 volt GFI protected from the start of the branch circuit. All nonmetallic conduit must be at least 18” deep, if not GFI protected."
In fact, this site has been pretty helpful in understanding the NEC section 680, and he points out this burial depth two or three times.

Either way, the conduit is all in place now, I need only wire the circuit at this point. I'm also not worried about passing any kind of inspection (since I'm out in the county and it is a previously installed pool, I don't need a permit), I'm mainly concerned with safety for me and my family. The previous wiring job was a death trap, literally. What I have replaced it with may not be 100% to code, but it is safe, and that's the important thing to me.

I saw that, and it got me to wondering: where would be the bonding point on this circuit, if not on the pump motor housing?

- 3: Use wire pulling lube aka "snot".
1- I'm under 40% fill. I don't have the numbers here, but I'm fine.

2- Conduit is already assembled and buried at this point. Since I've only got two 90º standard radius turns, I should be okay. Last night I tried taping the wires together and pulling/pushing them through, but I made the mistake of not staggering the wires when I taped them.

I'll pick up some lube today or tomorrow and try again, this time with a few changes. One, I'll stagger the wires to make negotiating the bends in the conduit easier, and two, I'll use some heavier nylon cord instead of the thin twine that I was trying to use last night (which was getting me nowhere). The lube should help, too.

Again, thanks everyone for your input in this thread. Not only has it helped me, but I'm sure it has helped more than a couple of lurkers out there, too.
