For a 7088 s. foot house with future plans for an inground pool, I'm thinking a 600 amp service. We just finished a pool, inground hot tub, with a pool house.
I ran a 400 amp service for it, partially because the POCO asked me to. (Because of the distance and wire size they had to use for voltage drop, they said they can't bend their conductors into a 200 amp meter base.) Actually, I'm glad we went 400 (320). Pool house had a kitchen, bath, and lounge room, mechanical room, all electric. Two pool heaters (which I encouraged them to go gas for those.) The pool control panel was 125 amp.
For large pools with a hot tub next to it, is 200 amps enough typically ? If the two heaters had been electric, 200 may be too little.
Thank you for advice.
 
The only thing square footage will give you is the general lighting load. You will have to factor in A/C vs. elec. heat (220.60) cooking equip. (T.220.55) elec. dryers (220.54) fixed in place appliances (220.53) largest motor x 25% (430.24) apply all demand factors allowed in Art. 220 and you can determine your minimum size service rating.
 
Just anecdotally, I'm in a 6,000 sq ft house with 200A service. 2 central A/C units, all electric kitchen, no outbuildings and no pool. Been here since April and not had an issue. I would think that 400A makes sense and that 600A is probably overkill. Whatever you do make sure the main panel is sized big enough for a sizable solar backfeed. My 2001 vintage combo Siemens meter pan has six spaces and no main breaker, but is rated at 200A meter socket. Nowhere does it say the bus is 225A even if it might be. So, getting a solar backfed in there is limited to 40A and I could use 60A.
