How to Wire an Electric Range

Invented in 1882, an electric range converts electricity into heat. Unlike many household appliances, an electric range uses a 220-volt circuit, rather than the standard 110-volt circuit. Even with the higher circuit, it is possible to set up an electric range without the help of an electrician. Use these tips to wire an electric range with a 4-wire circuit.


  1. 1
    Turn off the circuit breaker that supplies power to your electric range. Most circuit breakers are located in a basement, garage or utility room. Flip the breaker to the off position.
  2. 2
    Remove the plate on the rear of your electric range. The plate is a square panel covering the back of the range. Remove the screws that attach the plate. You will see a small power box housing 4 screw terminals, with the green screw being the ground terminal.
  3. 3
    Remove the round, metal knock-out inside of the terminal box by using a hammer and a screwdriver to push out the piece.
  4. 4
    Open the space inside the back panel. Loosen the 2 screws on either side of the strain relief connector to widen the space. Feed the loose end of the power cord through the strain relief entrance.
  5. 5
    Begin wire connection. Find the copper strip on the end of the 4-pronged cord. Connect the ground wire to the green ground screw, and connect the black wire to the terminal screw on the left side. Connect the white wire to the middle terminal screw, and the red wire to the terminal screw on the right.
  6. 6
    Position the cord properly in the space. Ensure that the cord passes through the strain relief clamp, and that it is clamped in an area of the cord that has thick insulation. Tighten the screws on the strain relief so that the cord is secure.
  7. 7
    Retighten the screws. Using a screwdriver, tighten the screws on the range cover plate so that they are taut enough to hold the cord.
  8. 8
    Return power to the electric range. Plug the power connector into the 220-volt outlet. Turn the circuit breaker back on and heat up a burner to test the connection. Move your range back into place, taking care to leave enough room for the power cord.


  • When replacing the range cover, make sure the power cord is arranged so that it will not rub on any sharp edges of the electric range.


  • Always turn off the power at the circuit breaker to the area where you will be working. To avoid electrical shock, make sure no power cords are plugged into any outlets in the area until you are certain you are able to turn the electricity back on safely.
