I am having problem with a residential load calculation. Mother & daughter in a 2 story, total electric house, with each one living on different floors, hence 2 kitchens, 2 clothes washers, 2 clothes dryers, etc..
2529 square feet of living 2 8KW furnaces 2 4.8KW heat pumps
2 ranges 2 microwaves 2 dryers 2 clothes washers
2 bath heaters @ 1250 watts 4 small appliance circuits
1 28,000 watt (4 30 amp circuit) tankless water heater
2 1250 watt bath heaters AND 30 amp 120 volt / 50 amp 240 volt
receptacles @ 2 locations for motor homes.
I come up with a 400 amp service, but others are bidding using 320 amp. Is my 400 amp correct, or am I miss figuring? Help would be greatly appreciated! Thanks, Joe.
