smaller gauge wire. Anybody I am getting this from a homeowner who said that a pool guy looked at her spa and said the wire size was to small and will cause the water to get to hot (this is one of her complaints). I have to go check it out next week because apparently the c/b is not a GFCI type. I told her to stay out of it for now. But I can't think of a reason why the water temp would increase because of know?
