Oven Cord and Wiring Oven for 3 Wire or 4 Wire

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.

Electrical output requirement for a buit-in oven and cooktop


Providing the existing switch outlet iscontrolled by a 30amp circuit fuse or trip, then there is no problem connecting the 2 appliances to the same switch.
If on the other hand, it is controlled by a 13 amp breaker, then you cannot connect both appliances to this, you would have to use 2 seperate sockets.
Hope this clarifys your question.

neither the stove top nor the oven get hot!


Hi and welcome to FixYa.com

First thing you want to check is the power supply (fuse or circuit breaker) to your oven.
Now, before you say "RescueTech it can't be the fuse because the indicators light up and I can set the controls!" read on-
Your range and oven elements are 220V units. This requires both legs of the 220 (L1 and L2) in order for them to heat up. Your indicator lamps and controls are 120V, therefore they will continue to work if one leg of the 220V feed is not present. It is very unlikely that all your switches and elements have failed at once. So start first at your fuse or breaker box. If you have cartridge fuses, you need an continuity tester or ohmmeter to check them. If you have breakers, there are two styles- One is a "single lever" style that controls both legs of the supply. The other style is a "double pole" breaker that is actually two separate breakers connected by a pin between them. Oftentimes one side will trip but not the other. You will actually be able to visually see this as the pin will appear crooked as one breaker is in the ON position and the other is in the TRIPPED position. Turn off the breaker (both sides will move together) and then reset it to the ON position. Now the pin should appear straight and both breakers should be in the ON position.

If the breaker seems to be fine, the next thing I would check is the terminal block where the range cord is connected to the appliance. As a journeyman technician, I often see where the installer failed to properly tighten the range cord's terminals when he/she installed the range cord. The appliance will function for awhile, sometimes for a few years even, but that connection gets HOT every time the range is used, and especially when the oven and all 4 burners are used together (Like on a HOLIDAY!) What will eventually happen is that the terminal will literally burn away and break the connection to one side of the 220. The result is anything "low voltage" on the appliance such as clock, lights, timers, indicators) will still work, however the elements will not heat up.

Before you start changing parts, check these things. I would be very curious to know how this one turns out. Just remember that the top burners and the oven have no connection to one another other than the supply voltage.

I hope this helps and have a happy and safe New Year from all of of here at FixYa!!
