This electric circuit listing is based on a single family home of 3000 square foot with the following electrical loads:

1- 12 kw electric range
20 kw of electric space heating (1 central elect. heating unit)
1- 5 kw electric water heater
1-central air conditioner, 9 kw
1- dishwasher, 1 kw
1- disposal, 0.9 kw
1- electric clothes dryer, 4500 watt

Note:
Smoke Detectors are not required to be on a dedicated circuit. Smoke detectors are typically shared on a lighting circuit such as the hallway lights, this way if the circuit is off for any reason it will be noticed.

Robert in Delaware asks:
Electrical Circuits
What circuits have to be wired with 12-2 wire?

Dave’s Reply:
Home Electrical Circuits

12-2 Type-NM cable is rated at 20 amps, therefore this cable is typically used for general purpose branch circuits such as kitchen GFCI outlets. However 12-2 Type-NM cable is also used for dedicated circuits for various small equipment such as a whole house vacuum system or a clothes washer.
