I have one other question. I found online at home depot and Lowes, that I can either this one from home depot:

or this one from Lowes:
http://www.lowes.com/lowes/lkn?action=p ... lpage=none
Which one would be better? Remember that I will be using a 50A breaker with AWG6 in the main panel, I am not sure if the 70A would be sufficient enough or if I should just stick to the 50A. My wife's cousin's husband is an electrician. I may be able to get some wire and maybe the spa pack from him, if he has any spare. I am not sure if he is residential or commercial.
Thanks,
Chris
