s for USA, Canada and countries using similar 60Hz mains supplies Conversion Dangerous and NOT Recommended Ummm no. If you did try to do it, you'd have a pretty good cha…nce of burning your house down. More Information: I want to say "no" you can't do this based on what you've told me. What matters here is the size of the wire, 240V is 240V and that part of it doesn't matter. A dryer uses #10 wire for 30 amps and a washer uses either #14, or #12 for Canada vs US. If you were to just switch out the receptacle you would run the risk of burning up the 15 amp wire as it's not designed to carry that kind of load continuously. If you have a wire stripper that has the awg wire gauges on it and it measures out to #10, then you can swap out the receptacle and breaker and convert this to suit yourself. If in doubt, always consult a licensed electrician. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
What is involved in installing a new 240V breaker in the main breaker box so you can add a 240V receptacle?
for USA, Canada and other countries running a 60 Hz supply service. You are going to need a number of things: * A 240V double-pole breaker of the right size for your load…, (Don't try and use two single-pole 120V breakers!) and the right type for your box (SquareD breakers for SquareD boxes, GE for GE, etc.) * A length of 4 conductor wire to run from the breaker panel to the outlet that is the right size for the breaker! Rule of thumb for wire runs under 50ft: 14 gauge for 15A, 12 gauge for 20A, 10 gauge for 30A, 8 gauge for 40A, 6 gauge for 50A, etc. Get 4 conductor wire even if you only want 240 (and not 120) for futureproofing. * A new outlet and box to mount it in. * Clamps to secure the wire to the box and breaker panel. Then you need to: * run the wire from the panel to the outlet. Leave slack at the panel, you need a couple feet inside it. * Wire the 240V outlet. Remember the color code: the black/red/brass screws are for the black and red hot wires, the white/silver screw is for the white neutral, the bare/green screw is for the bare or green-covered ground wire. * O ne slip and you're dead. So always shut the breaker panel main switch to OFF . * Connect the wires into the panel. Which bus is which should be obvious by the existing wiring. Remember to get your connections good and tight. * Put the covers back on everything, switch everything on and enjoy. If anything I said above wasn't obvious, buy a book. It will explain everything better than I can in text and serve as a handy reference on the job. If you are still not confident, hire a professional licensed electrician. Negligence with electricity is fatal. Addendum Some things to remember are: A - You must kill the whole box before jumping in it. KILL IT. B - never grab more than one wire - or contact - at a time! C - Try not to ground yourself out. D - always use the right size wire for amperage needed. E - You do not have to be a brain surgeon to wire in a circuit. If you are not totally confident with what you are doing definitely consult someone who will be nice enough to give you life saving tips instead of telling you to take a hike. 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.

This is a very simple procedure, but the fact that you ask the question indicates you should get an electrican to do this simple job. The installation is fairly simple. Its t…he calculations involved (for proper wire size, overcurrent protection size, etc) that require some electrical knowledge. I'm no expert on welders, but I know they can pull some massive amperage. Leave this one to the pros, or you could very easily cook your house.
Bare wires!?!?!?! For 240V you need 3 wires plus ground. Red and Black are hot, white is neutral. Don't mess with 240V if you have no idea what you're doing. It's not safe at …all.
How do you install a 240V 20A breaker and receptacle with 1 hot 1 neutral and 1 ground when there are 2 hot wires and 1 neutral?

Answer . \nThis question raises many others. Are you wiring in an office, a barn, or a house? Is the application to wire a pool pump, sump pump, an air conditioner,\nan o…ven, a heater, or what? Where is the appliance located? Is it new or\nexisting? Is it installed and grounded? How far is the application from the main electric panel? Is the wiring to run outdoors or will it be exposed to moisture, extreme temperatures? Will it be run inside a wall or left exposed? What is the amperage rating of the appliance or machinery or heating device? Will this line be dedicated to one appliance or machine? Have you identified the breakers to be used? If so what is the amperage rating? Is the circuit \nprotected? Is your electric supply single phase two wire, three wire, or 3-phase current? In what U.S. State is the intended application? \n. \nI am sorry. Your question cannot be answered. You see, the fact is if you did not know enough about electrical matters to realize that the question lacked vital detail you should not be doing your own wiring and should hire an electrician for this job. It is too dangerous to do it yourself. This doesn't\nmean you cannot learn. If you are very interested in obtaining more knowledge you might start with one of the more elementary but thorough paperback books: Wiring Simplified by H.P. Richter if still available. It was published by Park Publishing, Inc., 1999 Shepard Road, St. Paul, MN 55116. Good luck!
Answer . \nA "110" volt outlet cannot be converted to a "230" volt outlet. A 230 volt outlet requires a new wire run to the outlet rated for the appliance you plan on plugg…ing into it. Example an airconditioner that requires a 220 volt 20 amp circuit would have to have a 12/3 w/ground wire run to handle the load. The three wire are usually black,red,white. Black is for 1 120 volt line, red is for another 120 volt line and white is for neutral. On a standard 120 volt outlet there are 2 colored wires (black and whtie) and a bare ground. It's not an easy solution, but it is the only proper solution.
If you have a 240V dryer and installed 30A breakers on both sides of the line reads 120 and 120 how do you get 240 and you have a receptacle that reads 30A 125250 and still does not work?
Answer . you do NOT put two 110v breakers in. you put 1 two pole breaker in. the panel is designed to give you 220v off one side OR the other side if you use a 2 pole bre…aker on one side or the other side.. Answer . If you look at both 120V lines on an oscilloscope you will notice that they are both 120V to the neutral, but they are 180 degrees out of phase. This means that when one hot is at +120V the other is at -120V. So between the two you have 240V.\nIf you put your meter across both hots you should see 240V.\n. \nIf you do not see 240V across both hots you (or an unlicenced electrician) has wired the outlet without using a proper 220V breaker. You do not see 240V because the hots are in phase, to the voltage differential is 0V, not 240V. 220V breakers cannot do this, unless forcebly installed in the wrong type panel. More than likely someone tried to wire it with 110V breakers.
Answer for USA, Canada and countries running a 60 Hz power supply service. . By asking this question you are probably not quite ready to take on this particular task. The c…orrect answer to your question will depend on the distance from the breaker panel and exact location of the air conditioner unit, its voltage and its power rating. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you use the wrong size and type of cable for the job and/or put just one wire in the wrong place, you risk being killed by electrocution or you could even start a house fire. How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/County/State) and on the exact location of the electrical equipment you wish to be installed. If situated anywhere that is subject to water splashes, water spray, dampness or humidity - such as in any room supplied with running water pipes, like a kitchen, laundry room, bathroom, shower room, etc., or in a workshop, or garage (or anywhere outside a building in the open air, such as along an outside wall - or a pool-side area) in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you get any other answer here, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or even their life. 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. .

In hooking up a 240V Air Conditioner you have four wires but only three on outlet What three go on receptacle Red Black White Copper?
Answer . For a 240V with ground outlet you will connect black (hot) to one brass screw, red (hot) to the other brass screw, and bare (ground) to the green screw. Cap whit…e (neutral) with a wire nut. It is for 240/120V appliances.\n. \nIf you don't fully understand this buy a book. This is a very basic question. If you don't understand which wire is which you could make a serious mistake causing fire or death.
What size wire do you use to install a 40Amp breaker for a 240V receptacle for use with a 240V range?
For USA, Canada and other countries running a 60 Hz supply service. If you had to ask this question here you need to learn more about your local wiring code re all the item…s you must use for a new household AC power range circuit. Serious home fires can result from incorrectly installed new circuits. So that the new installation is safe and legal - and complies with the terms of your home insurance policy - you must use the correct type and size of cable, the correct type of circuit breaker and the correct type of wall outlet. From the local wiring code, a licensed electrician will know which size of wire to use because the answer depends both on the current to be carried (amps) and on the length of the run from the breakers on the main supply panel to the place where the outlet for the kitchen range is to be fixed. Another answer #8 awg Copper or #6 awg Aluminum but first of all you should check in the NEC wire sizing tables for the cable size given for your length of run. If installing in conduit install no more than 6 current carrying conductors, i.e. black, red, or white, or you must increase the size of your wire. If installing this circuit using a jacketed cable like NM-B then you should use a 4 conductor cable, not 3 conductor as in the old days. 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.

a 30 amp breaker will work. the formula is power divided by voltage and then use next size up
What size wire do you use to install a 20A breaker for a 230V receptacle for use with a 230V air conditioner?
A #12 copper wire with an insulation factor of 90 degrees C is rated at 20 amps.
Use a 10 AWG wire when a circuit is to be driven by a 30 Amp breaker. As with all home electrical projects, make certain that you understand and follow all local codes regar…ding any modifications that you are performing. If you have any questions, contact a qualified electrician or competent handyman, depending on state regulations.
For a 7000watts or 7kw a 240V then it is 30 Amp
