We recently put an addition on our home. I am looking to run a subpanel from our 200 amp service panel out in the yard at the meter (mounted to a pole), 75' to subpanel location.
In the addition we have 2 bedrooms, walk in closet, laundry room and bathroom. We also added on to our living room 10×15. All these rooms will have receptacles, lights and a 240 volt hook up for the dryer in the laundry room and baseboard electric heaters. (1 per room except laundry and living room) Total of 4 heaters. I currently picked up a 125 amp homeline 20 space 40 circuit panel box without main breaker. Is a 100 amp breaker from main panel more than enough? Can I use a 60 amp breaker to feed the subpanel? This is going to be inspected per NEC code.

Each baseboard heater is probably 15A (if not then check what they actually are), and the dryer is 30A. So you're already at 90A. The washer (is it frontloading?) will need 15A/2 (it's 120V), and so will the bathroom, so that's 105A. I can easily imagine all those running at once. Then you have some plugs and whatnot, but you probably won't max all of them at once.
Looks like 120A will be OK, but just barely. Is electrical heat really your only option? Can you use a gas dryer?
