ElecDryer, 240v/4500 w-heater, coil burner stove, & AC too much for 100A M.H. service

Electric Dryer, 240v/4500w water heater, coil burner kitchen range, & AC, too much for 100A mobile home service? AC is probably 2.5 ton I'm guessing for a 14x70 or 16 x 85 home.

Drier - 5kw, 20.83 amps, round to 21
Central a/c - 30 000 btu 10 seer assumed, condenser 2.6kw, 10.83 amps, round to 11, blower 400w, 3.33 amp, round to 4, total 15 amps.
Water heater, 4500w, 18.75 amps, round to 19
General plug loads, 1500w, 12.5 amps, round to 13
Stove, oven on, 3500w, 14.58 amps, round to 15

83 amps if heating water, cooling, drying clothes cooking at same time which is unlikely. granted if stove has all elements on high and oven at same time could draw a lot more current.



I counted 120v loads as if they were unbalanced and only on one leg, in the real world, the 120v loads would be split more evenly between legs.

The amperage is maximum per leg and 240v appliances draw the same amount from both.

Doubt 100 amp service would pose a problem in the real world, 200 amp of course would be better.

In general only electrically heated homes absolutely need a 200 amp service.
