I looked at the links and I know what you need, but I'm not going to answer your question for fear that you may try to do it yourself. Pool electrical install is more complicated than a regular household circuit. The consequences for error are severe. The fact that you say you are clueless says it all.

Please find and hire a licensed electrician with pool experience.

I'm sorry if I sound like a jerk, but, I don't want you or your family hurt.
