I recently had a pool installed with a commercial water slide. My sub panel is a 60 amp panel fed from a 200 amp main panel 70 feet away with 4 awg wire. The main and sub panels both have 60 amp breakers. I have 2 pumps powered off of this panel. Both are wired to separate 20 amp 240v circuits. I have 2 120v outlets on separate 20 amp circuits. 1 feeds an outlet for a natural gas pool heater and the other is an unused convenience outlet. The pumps are a 1 hp for the pool and a 3 hp for the slide. I want to add a hot tub next year. Is the sub panel and wiring sufficient to run a 50 amp circuit for the hot tub?
