I have installed a hot tub and am doing the electrical now. We have a 240 breaker from the panel in the house to the subpanel outside. Our breakers are Siemans outside and it is a cutler hammer gfi 40amp outside. Anyone know how to actually hook it all together?

Doing a search for Hot tub found this good post:
