Hi;
I'm sorry, but I'm closing this thread. It's not possible to answer your question safely based on the information you've given, but if I don't close the thread, someone may try.
Electrical wiring around pools kills people when it's done wrong, and -- frankly -- your question reveals the fact that you do not know enough to be doing your own wiring, with any reasonable level of safety.
I strongly, VERY strongly, recommend that you hire an electrician. It's a small job, and shouldn't cost too much.
Sincerely,
Ben / PoolDoc
