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
Electric Circuit Listing - Home 3000 sq. ft.
General Lighting, 3000 sq ft x 3 watts = 9000
2 Small Appliance, 1500 ea= 3000
Laundry (Washing Machine) = 1500
Total General Lighting, Small Appl., Laundry = 13500
Apply Demands, 1st 3000 watts
Balance(10500 watts) at 35 percent
Dryer (minimum 5k)
Range (from col C)
Add Fixed Appliance x 100 percent (not more than four)
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.
Questions about Home Electrical Circuits
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.

Installing Electric Circuits
Electrical Project Skill Level:
Intermediate to Advanced - Best performed by a Licensed Electrical Contractor.
Electrical Tools Required:
Basic Electricians Pouch Hand Tools and a Voltage Tester.
Depends on personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area. Electrical Safety:
Identify the panel circuit, turn it OFF and Tag it with a Note before working with the wiring. Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock.
Electrical Wiring Parts and Materials:
Electrical parts and materials for circuit wiring projects should be approved for the specific project and compliant with local and national electrical codes.
Electrical Codes and Inspections:
Installing additional electrical circuit wiring should be done according to local and national electrical codes with a permit and be inspected.
