If you have an Electric Oven, Range, or Cooktop
and need to change the style of cord
that you have on the appliance
or if you just need to install a cord
on a new cooking appliance
, you may have questions about where the wires need to go. This tip will help you to figure these questions out.
Remember to ALWAYS make sure that all power is disconnected BEFORE beginning your work!!
On the back, underneath, or on the side, of your range or oven will be a cover plate that will have the wiring connection lugs
behind it. A screw or two will need to be removed to expose the connection point. Always remember to reinstall the cover after you have finished your connections.
If you have a 3 wire cord
the plug will look something like this.
You will have a red wire, a white wire, and a black wire, on the other end from the plug.
The black and red wires will go on the two ends to the matching colors. The white wire will go in the center. If you have a bonding strap
make sure that you jumper that from the center lug to the frame of the dryer. If you do not have a bonding strap, then make sure to make one out of #10 ga. or larger wire and a couple of crimp rings. Green wire is preferable.
The connection will look something like this.
If you have a four wire cord the plug
will look like this
Here again, you will have the red, white, and black wires. This cord will also have a green wire. This wire gets connected directly to the frame of the appliance. With this cord, you do not need the bonding strap or wire. If you are converting from a 3 wire to a 4 wire
then remove the old bonding strap if there is one there.
This connection will look something like this.
When converting from a 3 wire to a 4 wire
you just REMOVE the bonding strap or wire and hook the green wire to the frame. If you are converting from a 4 wire to a 3 wire
then you ADD the bonding strap or wire. It gets hooked from the center lug to the frame.
Always make sure that the outlet that you are plugging into is wired correctly also. The black and red are each 110 volt legs
that have a voltage of 220 volts across them. The black and the red wires need to be wired to a double pole circuit breaker of the required amperage. The wiring needs to be large enough to support the breaker size that you use and the requirements of the appliance. For 30 amps. use 10 ga
. wire, for 40 amps use 8 ga
. wire and for 50 amps. use 6 ga
. wire. The white or neutral wire goes to the neutral bar in the power panel and the green wire goes to the ground bar in the power panel.
By following this tip you should be able to hookup a new appliance or convert your existing appliance cord. Recheck all your connections before turning the power back on to the appliance.
