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 chance 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 mat…ters 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.

Answer for USA, Canada and countries running a 60 Hz power supply service. . An appliance designed for 240V absolutely must have a 240V outlet installed for it; there is no way to properly power it with 120V. If you aren't able to install a 240V outlet yourself, you should contact an electrician…. . You'll have to install a double-pole breaker in your breaker box. As for the outlet, read the instructions and determine what size outlet (how many amps) you need. For the cables, if it's an air conditioner that requires 120/240V then you'll need a 4 conductor wire. (3 wires plus ground.) If it just requires 240V you'll need a 3 conductor wire. (2 wires plus ground.) For wire sizes, some recommendations, which exceed the National Electrical Code, are: 15 Amps or less: 12 gauge; 20 Amps or less: 10 gauge; 30 Amps or less: 8 gauge; 40 Amps or less: 6 gauge; 50 Amps or less: 4 gauge. Again, these values are over-sized but bear in mind that the actual length of the run is very important and must be taken into account when selecting the gauge of wiring to use for a new circuit. Best practice is to check with a licensed electrician or see Table 310.16 in the National Electrical Code. . 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 an electrician's test meter having metal-tipped probes (not a simple proximity voltage indicator) to insure the circuit is, in fact, de-energized. .

%REPLIES%. Answer . It would have to be a 30 amp breaker to use the full power of the welder.. Answer . I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A..… Answer . \nWith the 30 amp breaker you must have at least #10 wires feeding the circuit. (MORE)
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.

Overcurrent devices cannot be doubled up for higher voltages. You need breaker designed for 220V. While you are technically correct, you need the 220V breaker because it is designed so that you always get 220V from the two phases (as opposed to 0V from one phase) and so both "breakers," so to speak,… always trip together. Don't just use two 110V breakers you have lying around, it is not safe. The approved method is to obtain a 2 pole breaker of the right amperage to run your 240 volt appliance. Also approved but not used as much is a common tie bar that incorporates the two breaker toggle handles into one. The reason for this is safety, if just one breaker trips there will still be 120 volts to ground on the un- tripped breaker. Anyone working on the appliance thinking that the power was off could get a severe shock. This holds true also with switches to turn off 240 volt loads, don't just use a single pole (SPST) switch which just shuts off one leg, use a double pole single throw (DPST) switch which isolates the load completely.

If you install a 30A 240V GFI breaker will this be ok or will the cycles the dryer has prematurely fail the breaker?
I suspect you mean GFIC breaker. The dryer will not cause the breaker to fail.
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 the 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. (MORE)

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 oven, 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.

This kind of question scares me. Electricians are professionals and went to school to learn how to do this without a book in our hands. Please for the sake of your Family and neighbors hire a pro. The sales people at Home Depot are probably not Electricians! Answer Each country has its own ele…ctrical wiring regulations. For example, the UK, which operates a 230-V residential system, these regulations are specified in BS 7671:2008 ' Requirements for Electrical Installations ' (also known as the IEE Wiring Regulations, 17th Edition ). This book is available from any book supplier, including Amazon. (MORE)
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 plugging into it. Example an airconditioner that requires a 220 volt 20 amp circuit would have to have a 12/3 w/ground wire run t…o 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. (MORE)
If you have a 2 pole circuit breaker box and cannot get your 240V electric dryer to work should you place 30A on both sides of the box if you purchased a 30A receptacle that reads 125v250v?
Answer for trained people: . There is one mistake that a knowledgeable person can make, and wonder why it doesn't work. This happens in some breaker boxes if you place a skinny 240 volt breaker filling an odd location (counting down vertically) and the next even position below that. When this happ…ens, both hot lines are on the same leg. So, instead of 240 volts across the motor, you have no voltage across the winding, but the motor winding is entirely at 120 volts with respect to ground. The upper position of the breaker location must be an even position, and the lower position the next odd position.. Most breaker boxes alternate bus legs in horizontal strips, not vertical rows. The first two horizontal rows are on leg 1 (L!), the next two horizontal rows are on leg 2 (L2), the next two rows are leg 1, etc. This requires placing a double pole breaker where it spans both legs L1 and L2. . The following condition will occur if you have duplex breakers installed in your panel. This error happens most often when the number of breaker positions already used in the box is a multiple of 4, and you try to use the next available space on one side. The next two spaces on one side both have the same leg, so you can't put a 240 volt breaker there. But some of the boxes let you install it there anyway (mine has plastic bosses that prevent this). . You can use a voltmeter to check for this. If you measure 120 volts from each hot prong to ground, but no voltage between the hot prongs, this has happened. A neon voltage tester will show no voltage between the hot prongs, even though it shows voltage from hot to ground. . The cure is to move the breaker down one breaker space in the breaker box. You can put another 120 volt breaker in the empty space where the knockout was removed (since cover is required, and the knockout can't be put back), and reserve it for a future 120 volt circuit. (Since my box has wide knockouts, I had to install two dummy 120 volt breakers, one above the 240 volt breaker, and one below it. But they quickly found uses in extra 120 volt circuits.). NEVER use two single pole breakers for a 240 volt circuit, unless the handles are common tied together with a special device made for that purpose. (MORE)
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 breaker 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. (MORE)

If your generator has a 4-prong 240V 30A receptacle 8500W peak and your stick welder has a 3-prong 240V plug how do you make this work?
Answer . Before you follow any of these instructions, make certain that you check with the documetation that came with the generator, since I can't be certain of what your generator is doing.\nThe following assumes that the generator provides 220 output and is NOT 3 phase.\nIf it's 3 phase, all o…f the following is wrong and don't do this!\nIn general, 220 circuits have 2 110 "leg's" which are nothing more than a center-tap into the 220 source. It can be a center tap on a transformer or a generator. The center tap is designated with a white wire, and the two "hot" lines are usually designated with either black or red. In the case of your generator, if it is not a 3 phase circuit, the 4th wire is probably green which is the universal indicator for a ground wire. To be safe, it is a good idea to ground the generator using a long, copper grounding rod that has been driven into the ground and using a good sized wire (typically #10 or larger) connect it to the generator at the grounding lug, again, see instructions that came with the generator.\nTo make the welder work with the generator, you can "get by" connecting the white wire to the white of the generator or if you're using a plug connect it to the silver screw. The two black wires or the black and red wires are connected to the two brass colored screws. Whenever a ground wire is provided on a wire it should be connected to grounding screw of the plug.\nI hope this is enough information. If you have any questions, contact the manufacturer or a local electrician. (MORE)
\n. \nIf the 220V circuit is dedicated, is to derate the circuit to a dedicated 110V outlet. Replace the 220V breaker with a 110V breaker and install a 110V outlet in place of the 220V outlet. If the original circuit was 20A or greater go with a 20A breaker and a 20A outlet as Airconditioners are… fairly large loads. Do not exceed the current rating of the old circuit as that is all the current the existing wiring can handle. (MORE)

I wouldn't want to gamble my family's lives on my incompetence.....pkazsr. Blind leading the blind . 3 wire plugs are old and outdated. Way back in the old days they didn't ground equipment so plugs didn't have a ground. (Remember the old 2 wire 110V outlets on houses built before the 50s?) A few people got killed so they decided to add a safety wire. It took them longer to catch on with heavy appliances, but eventually they did. That it what the fourth pin is. Since many homes still have the 3 wire plug it is allowed in older homes. New homes must use the new 4 wire plug.. Changing your 4 wire cord to a 3 wire cord is the same as plugging a 3 wire 120V appliance into one of those 3 prong to two prong adapters they sell. Your appliance works now, but is ungrounded.. Don't listen to anyone who says to replace the new up-to-code plug with an older plug. That is the same as replacing your 3 prong 120V outlets with old two prong outlets! Ignore anyone who tells you to do so, they think they know a lot more than they actually do. Buy a new cord. It is cheap and safer.. Answer .

It sounds like you're trying to convert a dryer outlet to a sauna power source. You'll need to replace the outlet with a hard-wired connection (you take off the outlet and put a blank cover on the junction box) in that junction box and extend it with 14/2 (with ground) wire to wherever your sauna is.

The following is an educated guess. 240 Volts is 240 Volts. Unless the equipment inherently depends on some aspect of the frequency for operation [50 hertz instead of 60 hertz], it should work if you simply change the plug. WHY NOT CONTACT THE MANUFACTURER FOR ITS ADVICE?!

\n. \n Answer \n. \nSure, if you want to keep resetting it. To be safe change to a 20 amp and make sure the wire is no smaller than 20 gauge....pkazsr\n. \n. \n Answer \n. \nTo recharacterize your question, you asked, "Should an electrical appliance be interupted by a circuit breaker d…esigned to trip at the same request for power?" The answer is no because power availability should exceed demand. \n. \nAmperage is based upon demand. That is, if you have a 15 Amp demand, you need a breaker in excess of that demand. If my electric shaver requires 15 Amps to run, which is the equivalent of a buzzsaw, I don't want the circuit breaker to trip at that demand. A 20 Amp circuit breaker would be fine. \n. \nIt is a compromise. \n. \nIf the breaker is at 30 Amps it will power my 15A appliance without interuption. However, if I drop my 15A electric facial buzzsaw into water, the breaker will hopefully trip before I no longer need to concern myself about ever shaving again. That is, the breaker should furnish adequate power for normal use yet shut down when there is excessive demand, such as a shortage. \n. \nLike when my wife tests our breaker panel by throwing a toaster into my bath, ostensibly to warm the water.

How do you get 40A when installing a tankless water heater with an existing 240V line with a double pole 30A breaker?
Answer for USA, Canada and countries running a 60 Hz power supply service. . Getting 40 Amps .

If you had a wall AC unit that ran on 240V and you got a new one that runs on 120V how do you change the wall receptacle outlet wiring to be able to run 120V instead of 240V and how about the breaker?
\n. \n Answer \n. \nThere are several factors: the outlet configuration and connection, the supply wiring, and the breaker.\n. \nIt has been suggested that:\n. The 240v gauge wire may be thicker than the 120 volt gauge. The 120 is 12 gauge and the 240 is probably at least 10 gauge. The wire… itself will probably be okay. The outlet will have to be changed to a regular receptacle. The breaker for that circuit will have to changed to a 20 amp instead of the 30amp or so that it is now. I hope this helps you some.\n . \nHowever, this ignores the fact that you can deliver twice as much power at 240v than 120v using the same rating wire and breakers. P= v x i; double the voltage, double the power for the same number of rated amperes.\n. \nIn any event, the cable into the breaker box will have to be disconnected from the two-pole breaker and the black (hot) wire connected to a single-pole breaker (say, 20A), and the neutral (white) wire connected to the neutral bar. There should also be a bare or green grounding wire connected to the grounding (or neutral) bar. The supply wiring must be at least 12 AWG or larger diameter (i.e., a lower number is larger diameter). In an ordinary north American receptacle, the black "hot" wire goes to the narrow slot, the white "neutral" goes to the larger slot, and the bare "grounding" wire goes to the third prong, often via the green screw marked "ground". Local code may dictate exactly how grounding connections are made (i.e., directly from the cable or with green pigtail from metal outlet box connected to the supply ground and the device ground). If possible, install a GFCI for added safety.\n. \nNeedless to say, any necessary rewiring of breakers and outlets should be done carefully by a qualified electrician, and you may need a permit, if not an inspection. It is also possible that someone illegally connected more than one outlet to the same circuit, so you should make sure there are none before any conversion project is undertaken, and account for any "extra" wires in the outlet box.

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 correct answer to your question will depend on the distance from the breaker panel and exact location of the air conditioner u…nit, 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.

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. (MORE)
You should probably have a qualified electrician do this.. Be sure to be extremely careful if you chose to undertake this.. As a homeowner, you can do this yourself and take out the necessary permits.. To do this, you will need to install a double breaker (one with the bar across the two switched…. This will be a wider than normal breaker and will go across the two poles in the panel box). From the box, you will need to run 12-3 (or possibly 10-3 depending on the amperage) to the 220v outlet. The 3 wires in this set will be a black, a white, and a red. If using BX armour shielded, the metal jacket of the cable provides the ground. If using romex, there will be an additional wire, this will not be insulated and will be connected to the grounding bar in the panel box. The grounding bar will usually be opposite the neutral grounding bar (the bar where the white wires are hooked). While they are often times connected to eachother, it is necessary to keep the wires separate for code purposes. The black and red wires from the newly installed cable will be connected to the newly installed breaker. Be sure the breaker is OFF when installing the cables, as per the panel box will most likely be live. Also be sure that no wires comes into contact with any of the live terminals in the panel box. When working in a live panel box, work with one wire at a time and be patient.. Now that the panel box has been taken care of, you may now run the cable to the outlet and wire it up accordingly. When running the cable, try to avoid sharp bends and tack the wire using approved staples.. Finally, make sure to properly hook-up the outlet.. I cannot stress enough to consult the latest edition of the National Electric Code. Also, take your time and be patient. There is a lot of power in that panel box and requires your full attention.

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 items you must use for a new household AC power range circuit. Serious home fires can result from incorrectly installed new ci…rcuits. 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. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. (MORE)
8.. It is better to error on the next large size. # 8 THHN 90 degree wire is rated at 45 amps. If there is a possibility that the breaker is connected to a 50 amp load the wire will be undersized. A #6 wire is rated at 65 amps. For continuous use, a load factor of 80% has to be applied. 65 x .8 = 52… amps.. The only time the conductor can be smaller than the breaker size is on a motor feeder. Then the breaker is sized at 250% of the nameplate full load amps (FLA) rating of the motor. This is to allow the motor's starting current, which is about 300% FLA, to not trip the breaker on start up. (MORE)
A high voltage of 11 kV - 33 kV is used for electricity transmission in order to reduce loss of power due to resistance. This is because, using a lower voltage would mean a higher current, raising resistance.

How do you connect a European 240V appliance 3 wire plug with black and blue and green wires to a US 240V circuit?
European wiring has two principal colour schemes: On appliances from the last 40 years, and recent fixed wiring: Live: Brown; Neutral: Blue; Earth: Green with yellow tracer On older appliances, and in older fixed wiring: Live: Red; Neutral: Black; Earth: Green OR Green with yellow tracer. … Until you can satisfy yourself (beyond any doubt) as to which wires on your appliance relate to live, neutral and earth, you should NOT attempt to connect the appliance. Either check the manual or contact the manufacturer. Also, depending on the appliance, you need to consider that the US uses 60Hz alternating current whereas Europe uses 50Hz. This may or may not prevent the appliance working correctly. (MORE)
If you have a breaker that has a 120240v and your dryer has a 240v plug can you change the receptacle to a 240v?
if i have a breaker that has a 120/240v and my dryer has a 240v plug can i change the receptacle to a 240v
A single pole 15 amp breaker can only be setup for 120v. You need a double pole 15 amp breaker, which looks like two 15a breakers attached with a bar across the two actuators. Each leg provides 120v, or in the case of your breaker, 240v across the two legs.

What size wire do you use to install a 100 Amp breaker for a 240V receptacle for use with a 240V range?
A 100 amp breaker is too large for the average range. If you meant 100 amp service panel then the following installation will work. The most common size breaker used in North America for an electric range is a two pole 40 amp breaker. The feeder to the range receptacle will be a #8 conductor.
I = W/E. Amps = Watts/Volts = 6500/240 = 27 amps. A #10 copper conductor with an insulation factor of 90 degrees C is rated at 30 amps. If the load is continuous the conductor can only be loaded to 80% of its capacity. 30 x 80% = 24 amps which is too low for your load. Move to the next size wire whi…ch is a #8 which is rated at 40 amps x 80% = 32 amps. As long as no long distance runs are involved this wire size will work well. (MORE)
The breaker type be it a single pole or double pole will depend on what voltage the air conditioner operates on. Once the voltage is established, the sizing of the breaker depends on what the current draw of the air conditioner is.
Yes, a #10 copper conductor with an insulation factor of 75 and 90 degrees C are both rated at 30 amps.
In North America new homes are pre-wired for electric ranges with #8 copper conductor fed from a 40 amp breaker.
Answer for USA, Canada and countries running a 60 Hz supplyservice. Wire size is based on the amperage that the device draws. To findthe amperage of any device use the following equation, Amps =Watts/Volts 2000/240 = 8.3 amps. A #14 copper conductor with an insulation factor of 90 degrees C israte…d at 15 amps. (MORE)
