i guess i do have a few more questions.
if i were to use a spa panel, wouldn't i still need to have to install a breaker in the main panel, and run that to the spa panel?
and why is a 50 amp spa panel so much cheaper than buying a 30 amp gfi 240 v breaker?? seems odd... you could use the breaker out of the spa panel and put it into your main panel correct?
i'm kind of leaning towards going with the gfi extention cord, only because i'm trying to be as non-intrusive as possible being that i'm renting. that way i wouldnt have to mess with any panels, installing outlets anywhere, etc.
