How to Wire an Electric Stove to a Breaker Box

It is possible to wire an electric stove to a breaker box.

Determining Wire Size

An electric stove can either be wired with an electrical plug or directly wired to your home's breaker box.An electric stove can either be wired with an electrical plug or directly wired to your home's breaker box.
This connection is called a direct connect. You will need to have the proper size wire to complete this project. Check with local authorities to make sure you are following the proper electrical codes. If your local code does not allow grounding through the neutral bar, you will want to use a 4-wire connection. If your local code allows for grounding through the neutral bar, a 3-wire connection can be used.

Turn off the main electric breaker to your home. Determine the size breaker you will be using. A 40 amp breaker requires the use of No. 8 gauge wire. A 50 amp breaker requires No. 6 gauge wire.

Remove the conduit connection knockout on the back of the electric stove. Place a UL approved conduit connection in the hole left by the removal of the knockout.

Use a wire stripper to remove three inches of the wiring outer covering on both ends of the wire.

Use a wire stripper to remove one inch of the wire insulation from each wire on both ends of the wire. Be sure to allow enough extra wiring so the attachment process will be easier to complete.

Complete the electrical connection as described below.

3-Wire Direct Connection

Loosen all of the hex screw heads on the back of the electric stove. Do not remove the screws.

Locate the bottom center position terminal connector. Insert the white wire (neutral) from the electrical feeder line under the screw clamp.

Insert each of the two remaining wires under the remaining screw clamps. It is best to not cross these lines.

Use a screwdriver and securely tighten each of the hex screws. The wires should not be able to be pulled from the connection. If the connection is loose, continue to tighten until the wires do not slip or move within the hex screw clamps.

Tighten the locking ring on the conduit connector. Replace the terminal block cover on the electric stove.

Proceed to breaker box wiring instructions below.

4-Wire Direct Connection

Remove the ground link screw and the cup washer from the electric stove frame. Bend the ground link away from the electric stove frame so that it does not come into contact with the electric stove.

Connect the ground wire (bare copper wire) to the ground link using the ground link screw and cup washer. It is important to make this connection first. Do not allow this connection to touch any of the other wiring terminals.

Loosen all of the hex screw heads on the back of the electric stove. Do not remove the screws. Locate the bottom center position terminal connector. Insert the white wire (neutral) from the electrical feeder line under the screw clamp.

Insert each of the two remaining wires under the remaining screw clamps. It is best to not cross these lines.

Use a screwdriver and securely tighten each of the hex screws. The wires should not be able to be pulled from the connection. If the connection is loose, continue to tighten until the wires do not slip or move within the hex screw clamps.

Tighten the locking ring on the conduit connector. Replace the terminal block cover on the electric stove. Complete the connections by proceeding to breaker box wiring instructions below.

Breaker Box Wiring Instructions

Feed the wire into the breaker box. Drop enough of the wire into the box so that it drops past the position of the breaker. Remove the breaker from the breaker box.

Insert the black wire into the breaker. Tighten the screw until the wire can not be pulled from the breaker.

Insert the red wire into the breaker. Tighten the screw until the wire can not be pulled from the breaker.

Loosen two screws on the neutral bar. Do not remove these screws.

Insert the white wire into the neutral bar. Tighten the screw until the white wire is unable to be pulled from the neutral bar.

Insert the copper wire into the neutral bar. Tighten the screw until the copper wire is unable to be pulled from the neutral bar.

Tuck the wiring into the breaker box, being sure not to disrupt the other wiring. Connect the breaker into the breaker box. Make sure the breaker is in the "off" position.

Turn the main breaker to the "on" position. Turn the breaker providing power to the electric stove to the "on" position.

Things You Will Need

  • UL approved conduit connection.
  • No. 8 gauge wire and 40 amp breaker or No. 6 gauge wire and 50 amp breaker, depending on your situation.
  • Wire stripper
  • Screwdriver

Tip

  • An electric range requires a 220 to 240 volt, 60 hertz, properly grounded circuit. No. 8 or No. 6 wire can be used for the direct connection. Check with your local electrical codes to determine the size wire you will need.

Warning

  • Working with electricity can be dangerous and even deadly. If your skills or comfort level prevent you from completing these directions, consider hiring a professional to complete the electrical connections for you.
