The Basic Rules of Wiring a Double Oven

Picking a great double oven is not enough. Many questions would arise after purchasing, like “How do I wire a double oven?” you can do it quickly, but you must follow some basic rules. This includes:

  • For electrical safety, the oven must be grounded properly.
  • You must study the characteristics of the network before you connect the oven to the power supply. They must adhere to the power supply parameters of the oven, which can be found on a plate on the back wall.
  • A separate cable should be routed from the electrical panel to the equipment. Socket groups or other electrical appliances cannot be connected in parallel.
  • Circuit breakers with the right load capacity for the double oven must be used so they can secure the connecting circuit.

The Steps for Wiring a Double Oven

First, the electrical supply from the fuse box must be turned off. To make sure the power is turned off, you can use a non-contact electrical tester. It’s better to set the cardboard on the floor when you remove the oven, as this will reduce the risk of damage.

Remove the New and Old Oven Doors

Take off the old oven door before releasing the anchoring screws if you’re replacing it. If you’re replacing a double oven, though, you’ll need to remove both doors first. 

With the assistance of a second person, carefully lift the range out of the cabinet and cut the electrical cabling. Because the double oven is so heavy, it will be necessary to remove the door to make the procedure easier. Carefully place the handle side of the door down.

Measure the Cabinet’s Opening

Double ovens are typically available in three sizes: 24, 27, and 30-inch ranges. It’s best to measure the dimensions of your cabinet to make sure that it will fit perfectly. Complete measurements can also be found in the installation instructions.

Find junction box

3 inches below or above the cutout, a junction box must be installed. The junction box may be behind the wall if there isn’t one. To access electrical wiring, you must first cut an opening. 

Place oven feet

With the assistance of a second person, carefully tilt the double oven onto its back and set it on top of the cardboard to attach the feet. The height of the cabinet cutout has a big impact on how you attach the feet. The size of your cutout is also determined by whether you’re putting a double oven.

Make the electrical connection

  • After the feet are in place, place the oven where it will be put. 
  • Connect the wiring as directed, then remove all of the wires from the electric circuit. 
  • If the network connection wire is not removed from the furnace’s body. In that instance, locate a terminal block on the backside, select a section of wire, and secure its cores with the right terminals.
  • Make a mark on the wires of the double oven. A 3-wire Cu wire with a 2.5 mm2 cross-section is usually suitable for double ovens with around 3.5 kW capacity. Wires with veins with a 4 mm2 cross-section are suitable for high power. It’s preferable to use an RCD, which consists of a transformer and other electrical components, to protect your oven and yourself from the consequences of a short circuit.
  • Then, at the junction box, connect the ends of the cables like the input conductors.
  • Use wire connectors to join the cables. 
  • Be sure to match the colors. You should understand the color codes such as red, black, bare copper, green, and wire.

For Gas Ovens

Cover the thread seal around the valve nipple and tighten the gas valve coupler using an adjustable wrench if you have a gas leak. It’s preferable to brush a non-corrosive leak detection solution over all of the gas connections to check them for a leak. A leak is present if bubbles are found there. 

It’s best if you use the wrench to tighten the bolt. Plug the oven into the wall once the valves are fully pulled and no gas leaks are identified.

Complete the Installation

Lifting the double oven to the final installation area will require the assistance of another person once more. You must secure your oven with all of the screws that came with it. Reattach the doors with any trimming supplied if you removed them to make the installation process easier.

You should remember that a double oven range necessitates additional space for the cooking cavity as well as the electronic components. So, you must install the oven within a cabinet and into the wall.

Do Double Ovens Require Two Outlets?

Your double oven can run on gas or electricity, depending on the utilities accessible in your location. The power requirement for a gas oven is a standard, grounded wall outlet. 

When installing a double oven, the manufacturer recommends avoiding using a GFCI outlet. Also, make sure the outlet is grounded and that the ground from the oven power wire is never disconnected. If you come across an outlet without a ground, you should ask an expert electrician to change it with a grounded model. Never substitute an adaptor for a grounded outlet.

Do Electric Ovens Need Special Wiring?

Electric stoves are high-demand appliances that require a 120/240V circuit and receptacle, which necessitates special wiring. While gas stoves are plugged in to supply power to run vent fans, timers, and other accessories, they require ordinary 120V household circuits.

Some stove labels may mention a voltage rating of 250, 230, or 220 volts, but this all means the same thing: the stove uses the full voltage available at the electrical panel, which is nominally 240 volts.

Frequently Asked Questions

Does a double oven need its own circuit?

All electric cooking appliances need their radial circuit. Sharing a circuit with another kitchen appliance is not recommended for the oven. You should keep it as close to the appliance as possible to avoid any potential kitchen trip hazards, but not so close that it poses a fire threat.

Do you need a 220 line for a double-wall oven?

220-volt outlets and 110-volt outlets and receptacles are standard in every home. An electric stove is a powerhouse in case of electricity usage. As a result, you won’t be able to plug them into regular 110-volt outlets; instead, most stoves will require a special 220V outlet.


A double oven is a great addition to any kitchen. The double oven not only allows you to create two dishes at once, but it also allows you to make one meal while keeping another meal warm in the other oven. 

If the double oven meets your needs and matches your lifestyle, it can be an excellent investment. Moreover, the methods mentioned above can be for people wishing to learn how to wire a double oven.
