How To Connect Electric Stoves

Save

New electric stoves are not sold with power cords installed because of the different receptacles still in use. Some older homes have a three-prong, plug-in wall receptacle for the stove, while newer homes are equipped with a four-prong plug-in. New stove connections are compatible for either a three- or four-prong cord. With the proper tools, materials and basic wiring knowledge, you can connect your electric stove in 30 minutes.

Things You'll Need

  • Voltage tester
  • Flathead screwdriver
  • Phillips screwdriver
  • Combination pliers
  • Cable clamp
  • Turn off the power supply to the electric stove receptacle at the main panel. Tag or otherwise mark the circuit breaker to alert others of the work being done.

  • Test the receptacle with a voltage tester to verify that no power exists. Place one probe of the tester in the upper slot and the second probe in either slot to the right or left of the upper.

  • Locate the terminal cover plate on the backside of the stove. Remove the plate retaining screw with the appropriate screwdriver.

  • Remove the metal plug from the stove terminal box with a screwdriver and combination pliers. The plug is a removable metal disc located at the bottom of the box. Push the disc at its edge with the screwdriver and twist it from the box with the pliers.

  • Install the cable clamp in the open slot. Pull the terminal end of the stove cord through the cable clamp.

  • Remove the three terminal screws from the terminal block, or bus, and the green ground post screw below the bus with a Phillips screwdriver. Turn the screws counterclockwise.

  • Connect the white neutral wire from the cord to the center terminal on the bus. Insert the terminal screw through the wire loop connector and tighten the screw clockwise with a screwdriver.

  • Connect the red cord wire to the terminal to the right of the white neutral one.

  • Tighten the terminal screw.

  • Connect the black wire to the terminal to the left of the white neutral one. Secure the wire with a terminal screw.

  • Connect the green ground wire from the cord to the ground post below the bus with the green post screw.

  • Tighten the two cable clamp screws with a screwdriver.

  • Replace the terminal cover plate and secure the plate with the retaining screw. Tighten the screw clockwise with a screwdriver.

  • Insert the plug into the wall receptacle until it is fully seated.

  • Position the stove into its recess and restore power.

  • Remove all tags and markings from the main panel.

Tips & Warnings

  • If the cord has a four-prong plug, remove the copper grounding strap from the neutral post on the bus prior to connecting the white neutral wire to the post. If the cord has a three-prong plug, the strap must remain in place.
  • A 1996 National Electrical Code revision requires all electric stoves to be wired with a four-prong plug. Homes built prior to 1996 may have three-prong plugs.
  • Follow all manufacturer recommendations regarding warranty.
