sub panel that services the hot tub and swimming pool. We had a 60 amp sub panel already out there, but the wiring was on the small side to service the hot tub alone, let alone the pool as well, so we replaced it with Aluminum 2-2-2-4 (I think... it's thick ass wire, so don't quote me if it's 2-2-2-4 or 4-2-2-2 or something like that...) We put a new sub panel out there, put in wiring that can handle more than what we'd ever throw at it, and replaced the 60 amp service that was going to the sub panel with 100 amp breaker to that panel. The sub panel has 50 amp GFCI to the hot tub, then a 20AMP GFCI to the pool, and then an additional 20 amp outlet in case we need to plug anything in. it's all in weather proof box.
