Scotts, The Jecuzzis I have wire usually require a 50 amp. GFI, and I usually get them from the local electric supply house or Lowes has a weatherproof panel that comes with a 50 amp. GFI that is designated just for jecuzzis. In my area the panel and breaker at Lowes is around $90.00, which is a good price considering the breaker itself usually costs around $90.00 or so at my supply house.. Hope this helps....
