Code for Pool installation

[SethN]

I am DIYing a tranmission line to a pool pump. I am unable to find code specifics in the NEC 2002 at the library. I know generally what must be done but need to know code on the following:
How deep to bury wire?
What type of wire for underground?
How to ground the pool and motor according to code?
Other advice?
Please help
Thanks
Seth
