I am stumped on this I need to now the total net load and the total load service for a 1800 square foot home with 11 kW range and a 6 kW 240 V dryer I have looked at the back of the NEC and I need to check my answers thank for any help?:mad:

Assuming no heat or AC, I arrive at 80.89 amps.

The range only needs to be calculated at 8Kw.

The dryer at 6Kw.

3 watts per square foot x 1800 SqFt=5400 watts+3000w small appliance+1500 laundry.

First 3000 watts at 100% plus the remaining at 35%+8Kw+6Kw/ 240 volts=80.89 amps

What is the minimum number of 120-volt, 2 wire branch circuit that would be required for this home?

3 watts per square foot x 1800 SqFt = 5400 watts/120 volts = 45 amps / 15 amps per circuit = minimum of 3 -15 amp general purpose lighting circuits.

The keyword is TK's last post is "Minimum".

You can put more circuits in to meet your needs, but you cannot put less then 3 circuits.
