Wall Oven Wire Size-What You Should Know Before You Buy

Wall Oven Wire Size-What You Should Know Before You Buy

Are you thinking of getting a new oven and wondering if your existing wall oven wire size will work? Chances are it won’t and will be too small.

As a general rule traditional wall ovens used just a 240 volt 30 amp feed wire. However move wall ovens today do more and are larger which usually require a larger 40 amp or 60 amp 240 volt power feed. These sizes respectively would be #8 copper awg or #6 aluminum AWG.

We will get more into the wattages of oven sizes below so read on.

1.What size breaker do I need for a single wall oven wire size?

Wire sizing chart noted above. A single wall oven is used either in a standard household setting or in a commercial kitchen. Typical household ovens include the 240 volt 50 vamp feeder. The 240v #^ copper wire feeds the oven into the main electrical panel.

To do this the wiring requires a main breaker in series with the power feed line. What size breakers do I need for a double wall oven? A double wall oven is used either in a standard household setting or in a commercial kitchen. Typically household ovens include the 240 volt 60 amp feeder. The 240 volt #6 copper wire feeds the oven into the main electrical panel.

This same 60 amp breaker is used on a secondary side panel breaker. Do I need a completely new panel? Not if the existing wall oven has not been replaced within the past 10 years.

2.What cable do you use to wire oven wire size?

You should be using either a #6 aluminum or #8 copper wire but the wire would normally be #10 to #12 AWG copper wire with an old wall oven. Should you buy an oven that has a cable running through it? This would be fine if you were wiring a wall oven from a home or a commercial outlet and you don’t want it on your job site but not many new wall ovens have this feature.

So what will the ovens next generation do? I just spoke to a commercial electrician who told me that the wall oven next generation will have a 30 amp or higher 30 amp power feed that is always on.

The next generation wall ovens will be cable operated and will have the ability to cook up to 700 c.f.F. The oven will have the ability to run using the solar energy from your roof or utility meter so you don’t have to run the oven in off-peak hours.

These newer ovens can draw up to 60 amps depending on the wattage.

3.Can an electrician install a wall oven wire size?

It depends how old your oven is and what type of oven is it. It could be impossible to wire your oven properly. In some cases you could try making your own wire by cutting a length of #4 aluminum wire and splicing it to the #8 wire.

Just remember you cannot use a standard 120 volt plug (Type A or B) on this type of wire. It has to be an AC-40 plug. Some tools like this are available at many hardware stores. What’s the difference between a wall oven, range hood, or cook top?

There are three different types of cooktops. The first is a wall oven, the second is a range hood or cooktop and the third is a cooktop. How do I fit a wall oven into a chimney? To avoid a chimney fire it is highly recommended to cut the rear of your wall oven down to the width of the chimney.

4.How many amps does a wall oven draw for wall oven wire size?

A typical wall oven that gets up to 425 degrees can draw as much as 40 amps. This is how much current an appliance draws from the wall. At times, you may see power amps listed on an electric bill. These are the amps used by each appliance.

In many cases it does not help you to know the actual current used by a wall oven. Typically wall ovens in the range of 450 to 450W output power would draw an average of 150 watts with a 6 amp 30 amp 240 volt power feed.

This would provide ample power to bake a cake, bake a cookie or even roast a chicken. The wiring is critical, you will find you could run the wall oven with a 40 amp 40 amp power feed. If you need an oven, do not upgrade to a wall oven that is not equipped with sufficient power feed.

5.Does a wall oven need 220?

I haven’t found any information that would support the belief that the original wall ovens did not use 220 volt power. This would seem to suggest that they did. Does a wall oven need 220V power? I would say it’s not likely, but not impossible. I say not impossible because there were small and some very tiny wall ovens that used 220.

However I would say it is unlikely because such wall ovens are generally a low wattage type. They are used where high wattage, and typically larger wall ovens, are too large. Do I need to get an electrician to do the installation of my new wall oven? No, but I would recommend having the electrician install the 240 volt ground outlets to the outside of the new oven.

220 volt is more of a European voltage as 240 volt is North America

6.Can I install a wall oven myself?

Almost certainly not! If you are considering adding a wall oven you should get a professional installation. A wall oven installation is extremely time consuming and dangerous. It is impossible to tell if your wall oven will fit or not.

Wall ovens do not come with any instructions. Always ask the installer for the instructions for your specific wall oven and have him/her walk you through the installation steps. What oven accessories do I need? Do you want a glass top or not?

If your oven does have a glass top you need to be sure you have the proper clear glass pan to put over it. You will also need a protective cover to put over the glass top to prevent anything from getting stuck inside the oven. Make sure you use a high quality cover or this could lead to thermal stress cracks.

Hire an electrician and a carpenter to do the installation.

7.Can you install a cooktop and wall oven on the same circuit?

You can do it but it’s illegal in the U.S. and in most other countries. This can lead to electrical problems if the two circuits are adjacent to each other or are next to each other on the same circuit.

Be sure to research your local electrical codes first and be sure that installing them next to each other is legal. Does wall oven installation require a license? No it doesn’t. There are no license fees or licensing required to install a wall oven. There are some regulations to follow though.

The electrician needs to know when to start the wall oven installation (he usually does this before the electrician is hired). He also needs to know to install an overhead light switch when installing the wall oven wire size.

8.Which is better wall oven or range?

Evaluate what you are getting when you purchase a new range/oven. You want a range that can produce a few to several hundreds of KW. Once you have that knowledge, it then makes sense to get the wall oven with a similar wattage.

It may save you some money over time because you will only need to service your new oven once or twice instead of a few times per year on your range. The most important question of all to ask is how much more efficient will your new range/oven be? Typically by having an accurate ratio of the size of the range to the size of the wall oven wire size, the efficiency difference can be significant.

Wall oven wire size vs range oven wire size are close to the same. Standard wire sizes for ranges are 40 amp 240 volt plug in type.

9.Does a wall oven need a vent?

Does a wall oven really need a vent? No. If you have space in your kitchen, a wall oven vent is unnecessary. In fact it can cause more damage if not installed properly. Also a vent can put your wall oven out of temperature zone. How to find the right size wall oven If you are having an old wall oven installed in your kitchen or need to do repairs in your wall oven, here are the different wall oven sizes and the measurements you need to know to get the right size oven.

1.#8 B.C.C. Wire (4.8 kV AC) This size is the standard for all wall ovens. It is the largest wall oven size. 2.#6 AA Wire (40/120 V AC) A small adapter called a #6 AA adapter is sold in many stores to fit on #8 B.C.C. wire and thus can run a wall oven. It can be useful when connecting new wall ovens to an existing oven.

10.Can you put a wall oven under a counter?

No. This is a very common myth. Of course you can but it won’t be very safe as the oven could come loose and fall on the top of the cook. And that’s not exactly something you want happening when you’re standing right there.

The best way to get around this issue is to place your wall oven on a countertop to keep the oven and cooktop out of the way while you’re working. Why should you buy a wall oven from LG instead of Samsung, Bosch, or Electrolux?

If you’re looking for a wall oven that is easy to install, they might not be the best choice. They tend to be larger and more expensive. Samsung offers the highest quality ovens in the U.S. today.

11.Can I put a wall oven in an island?

There is no reason you can’t put a wall oven in an island. You’ll need to make sure you have a connector in the appliance outlet for the wall oven’s 240 volt AC line.

You can usually buy adapters that fit a specific standard outlet for this purpose. Don’t forget wall oven safety When it comes to safety remember you need a 4-wire open circuit breaker to operate a wall oven, regardless of appliance brand.

An 8-wire open circuit breaker can be added if you want to save space. Is my oven’s wiring safe for a wall oven? As mentioned earlier it’s the connection to the wall that’s unsafe, not the appliance itself. If you have older appliances the wall may be insulated in a way that may not be good for the wire wiring.
