I would like to install a subpanel to supply power to a pool house, I have a total of 10 circuits, listed as follows.
3 20 amp to support gfi over bar and bath sink
1 20amp for refer
1 20amp to support 14' of 220v electric hydronic baseboard heater
1 20amp to support 12' of 220v electric hydronic baseboard heater
1 20 amp to support electric hot water heater
3 15 amp to for lights and outlets
The sub panel will be located 40' from the main panel. I have 3 questions. What gauge wire should I use, What amp breaker should i use, and should i put a breaker in the subpanel as well as the main.
