Looks like I'll be upgrading to the 400 amp service. I figured approx 138 or 170 amps on the exhisting service (not sure if it has the heat strip supplement on the 2 heat pumps).
He will also be adding an addition with a 72 amp load figured by the Arch. So with adding a 50a spa, a 240 20a water fall and the addition it is over the 200 amp service. I will probably install the 400 amp panel at the exhisting side of the house and add the 200 amp sub panel on the back of the house. Which means possibly piping through the garage all the way to the back.
