I want to setup a sub panel to run my pool equipment. For now, all the equipment that I'll have is a 1.5HP Hayward Matrix 2-speed pump, a Aquatrol SWG, a Hayward Elite low-voltage pool light, and a convenience outlet. But in the future I want to add an electric heat pump that will keep my water in the 85-90 degree range from May - September. I haven't really completed much research yet on the size of heat pump that I'll need. I was considering running a 60 amp circuit from my main to the sub panel. It will be about 55 ft from main to the sub. Will that be enough to run most heat pumps and my other equipment?
