I currently have a 200amp service feeding house including a 20amp 2 pole pool pump and a 60amp 2 pole pool heater/cooler, these circuits are not GFCI protected. I would like to replace the pool circuits with GFCI breakers as well as add a 50amp RV plug.
All single pole circuits have already been changed to tandems and I am out of space in panel. I think a sub panel is best, is there another option? If I do a sub panel is this circuit correct?
100amp breaker in main panel
#4/4 AWG 5 feet to sub panel, sub panel neutral and ground not bonded
20 & 60amp GFCI breakers in sub panel feeding existing pool circuits moved to sub panel
#4/4 AWG 12 feet to RV 50amp plug with one leg also feeding a 120v receptacle
All circuits have no neutral or grounds connected to any other circuit except the sub panel bus bars. am I correct, and is there anything I'm missing to make this up to code and safe? Thank you!
