How do you rewire a 120V circuit to 240V for an oven?

The plain answer is that you can't! There is no 110 Volt application I can think of that would have a heavy enough [large gauge] wire at the point you want to convert it that would service a 220 Volt oven.

Ask a licensed electrician to run a new cable of the proper size to new breakers of the proper size!


As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

An electric oven must be on a dedicated circuit. Unless you already have a 220 Volt circuit available, you will have to run a wire from the fuse panel to the stove. Call a licensed electrician.

Sounds to me like whatever circuit you're trying to connect the oven to is not meant for the oven. You need the same wires to run back to the panel as the ones in your wall oven.

Short answer: probably not. Longer answer: It depends on the size of wire feeding the stove, the stove amperage, and what you intend to connect to the new 15A circuit. If you just want to wire a light for the garage, sure go ahead. If you want to install a receptacle for a microwave oven, no way. Make sure you put a fuse to protect the circuit you are connecting.

No The wiring isn't big enough to carry the load of an electric range Christmas is no time for a fire! Call an electrician!

I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.

No. If the heaters are designed for 220V they cannot fun off of 110V. Also running a 1500W heater off of 110V would require a dedicated circuit. So four 1500W heaters would require 4 dedicated 110V circuits.

The burners will most likely be 240V. By keeping the range at 240 volts it will use less amps that at 120V. Say a range and oven is rated at 9000 watts. Watts = amps x volts. 9000/240V = 37.5 amps. 9000/120V = 75 amps. As you can see at 120 volts the amperage is double over 240 volts. You would need a 100 amp breaker and #4 wire to accomodate the range on 120 volts.

Could you please give us a name of a 240 V 60 Hz microwave? Thank you

No. You will be one wire short. If you managed to wire an extra wire, the current would also be to high and you will risk fire. Like a bread toaster coil that turns red. Your best case scenario for the existing wiring will be 12-2. The minimum you need sor an electric range is 6-3. You are are 30A down and 1 wire short, and that's if you're lucky.

You might be able to plug in a 240V American oven range into a European outlet depending on the type of plug. SomeÊAmerican high-powered appliancesÊhave 3 or 4 pins, which may require adapters to plug into European outlets.

No, the electrical code requires that each be on it's own circuit.

It will work if, the dryer plug you are using is the same electrical voltage as the oven. If your oven is electric, it is 220 - 240v, if gas, 110 - 120v. A 220 plug has either 3 or 4 prongs, depending on your appliance being a 3 or 4 wire system. A 4-wire system will have a red wire (110v power), black wire (110v power), white wire (neutral/common), green wire (ground). A 3-wire system will be missing the white or green wire. 110v system (gas oven or dryer) will have a black (power), white (neutral), green (ground). It will work, but be limited. Dryer circuits are 30A, whereas oven circuits are 50A. You cannot just upgrade the dryer wiring to 50A as it is not rated for that and will start a fire. To use the oven properly you need to install a properly rated circuit. Do it right or don't do it at all. Negligence is fatal with electricity.

In residential applications, the supply voltage is between 200 and 250V. Nominally we call this 220v or 240v depending on who you ask.

industry standard practice. the electrical load from a combination range is the same as the combined loads from a wall oven and countertop. so your panel and electric service will handle it. BUT the range will be on a single circuit and you must ensure that the range circuit requirements are met. the circuit requirements are on the nameplate. for example, if the range requires a 30 amp circuit and your wall oven was a 30 amp circuit then you can use the wall oven circuit. but if the range requires a 40 amp circuit, then you have to pull a 40 amp circuit from the panel to the range.

To switch from a gas oven to an electric oven, you'll only need to purchase the oven, close the valve on your gas line, and make sure that you have a proper sized circuit available in your home.

Are you certain that you mean "amps"? Maybe you mean 110 VOLTS. The voltage in most home circuits are 110 volts except for a few appliances like driers, well pumps, hot water heaters, etc. And even those appliances probably only use 30 amps or so. The whole house may only have the capacity for 100 amp or maybe as much as 250 amp service. And to answer the question, a 220 volt appliance would not work on a 110 volt circuit.

a 30 amp breaker will work. the formula is power divided by voltage and then use next size up

Check the circuit breaker to see if it tripped.

If it's an electric oven, the fuse may have blown, or the circuit breaker may have tripped. Do you know where your household fusebox/ breaker box is?

In an oven. The "hot" wire is in series with the ove thermostat and provides an isolated circuit for turning on the oven element(s).

You'll have to change the wiring and the receptacle. Your oven is most likely 4-wire, and your dryer circuit is 3-wire. Even if your oven is 3-wire, it will need more amperage than the dryer. Ovens typically require 30-40 amps, which will require a circuit (wire and breaker) rated for 40-50 amps. The range plug is designed to go into a 240v, 50a receptacle, so I would make my new circuit 50 amps, with 8/3 (with ground) romex.
