A range is a stove and oven combined in one appliance. Depending on your home, you will have either a gas or an electric range. Electric ranges plug into a wall outlet behind the stove, or connect directly to your home's electrical system. Properly installing the power cord or direct wire is a very important step to ensure that the range is both safe to use and will not be damaged by improper wiring.
Turn off the oven circuit breaker in your fuse box.
Remove the lower rear cover of the range to expose the terminal block. To remove the cover, remove the screws or bolts that hold the cover in place.
Remove the knockout ring at the bottom of the terminal block, using pliers, if you're using a power cord or if you're installing a 1-inch conduit wire.
Screw a squeeze connector (sold separately from the range) into the hole at the bottom of the terminal block if you're using a conduit cable. Connect the strain relief connector with the screws included with the connector to the bottom of the terminal block if you're using a power cord. The strain relief connector is included with most ranges.
Insert the conduit cable through the squeeze connector and through the hole, or insert the power cord into the strain relief and through the hole on the bottom of the terminal block. Make sure you leave enough slack so the cables can reach the terminals. Tighten the screw on the side of the squeeze connector, or the screws on the strain relief connector, to secure the power cord or conduit cable.
Remove the three terminal screws from the terminals. If you're installing a four-wire power cord or conduit cable, remove the grounding screw located just below or above the centre terminal, as well as the ground plate or cable. Do not remove the grounding screw or grounding plate if you're using a three-wire cord or conduit cable.
Insert one terminal screw into the ring connector on the end of the white cable, and then screw the screw with the cable connected into the centre terminal. Make sure that the grounding plate or cable is still connected after the white cable has been installed.
Connect the black wires to the left and right terminals, following the same procedure as described in Step 7.
Connect the green or bare grounding cable to the grounding post if you're installing a four-wire power cord or conduit cable.
Replace the terminal cover and secure it with the screws that were originally removed.
