Can a generator providing 240V 20A operate a 240V clothes dryer?
The reason is to give the dryer more heating power for a given size of wiring at a safe current taken from the main supply panel. Electrical power is calculated by multiplyi…ng the voltage by the current drawn. So if a dryer runs on 240V (V) and draws 30 Amps of current (C) , its power (W) is given by W = V x C = 240 x 30 = 7200 Watts (= 7.2 kiloWatts) To get the same power from a 120V supply the dryer would have to draw 7200 Watts divided by 120 Volts = 60 Amps. But that amount of current is over half the maximum current capacity of the usual 100 Amp mains supply panel that is fitted in a normal-sized house! In USA, Canada and other countries using the same 60Hz power system, houses are actually supplied with 240 Volts to the main power supply panel. This is split into two 120 Volt circuits which, between them, feed all the house's 110 Volt socket outlets. The common neutral wire is connected at the center point of the split 240 Volts on the main panel. So it makes good sense to use the full 240 Volts for a powerful appliance such as a clothes dryer because then the current can be reduced to only 30 Amps. That is only about a third of the maximum current capacity available from the usual 100 Amp house mains supply panel. There are also serious issues to be considered such as the size of of the wiring - to carry current safely, without overheating, wiring would have to be much thicker to carry 60 Amps instead of 30 Amps - and the sizes of power breakers required to protect the circuit in the event of a fault developing. Faults can occur due to accidental damage or to breakdowns in several places around any electrical circuit: * in the appliance itself (due to overheating from excessive weight of clothing, or build-up of fluff, or heating elements simply burning-out after many hours of use) * in the appliance's own cable and/or plug * in its wall socket outlet and/or * in the wiring from the breakers on the main supply panel to the outlet.
If a circuit breaker is a 30A 240V for a dryer and the dryer calls for a 20A do you need to change your breaker?
No, you're fine. Answer Breakers are mainly used to protect the wires (and people), not the appliance. The appliance should have its own overcurrent protect…ion (a fuse usually). The 30 amp breaker will work in this case. Answer First off, dryer outlets are usually 30A as a standard, just like normal wall outlets are 15A. Secondly, you want your expected load to be 80% of your breaker size. So, a 20A load would call for a minimum 25A breaker, they just rounded up to the standard 30A breaker. (Which has a maximum expected load, by this rule, of 24A.) Good question though.
You really cant do it because a 220 has a heating element in it to dry the clothes unlike gas that uses fire to dry the clothes and the 120 is to turn the drum.Your drier will… keep poppin breakers which isn't good at all. Outlets and Power (110V outlets and 120V outlets are practically the same for this discussion. I will refer to them as 120V. Same with 220V/240V outlets.) By 110V outlet I'm assuming you mean a standard US 120V 15A outlet. This outlet can provide a maximum of 15A at 120V. This means the outlet can provide 1,800W of power. ( Volts x Amps = Watts ) This is the maximum amount of power this outlet can provide, no more. Also, this is assuming nothing else is drawing power off the circuit this outlet is on. If you try to pull 1800W from an outlet and plug anything else into this circuit, the breaker will blow. Your dryer is designed to run off a 30A 240V circuit. Let's say, for argument, it draws 24A at 240V. This means your appliance requires 5,760W of power to run correctly. This is 3.2 times the absolute maximum amount of power your 120V outlet can provide. There is no way you can run this appliance off this outlet. You have a larger problem here than the voltage difference. %REPLIES% You can't, you need both a and b phases. You need to install an 240v receptacle. And don't upgrade to 240V by using the same wires!! Some complete idiots will try this and burn the neighborhood down.
Answer It will operate assuming you have a 120/208V 3 phase system, but it will not get as hot as it would on a 240V system. To wire it just use 2 hots in…stead of 3 and connect the neutral.
Probably, because a "220V dryer" and a "240V dryer" might be the same thing if you're in the United States. Most electricity in the U.S. can vary within about 5% of 12…0V (114V to 126V) for single-phase, two-wire current (commonly called "110"). For single-phase, three-wire current (split-phase current, commonly called "220"), the voltage can vary within about 5% of 240V (228V to 252V). So, as long as the holes in the outlet and the plug from the dryer have the same configuration, the dryer should work. If not, replacing the outlet so that it matches the plug should be all that's needed.
N electric clothes dryer draws 22 A of current from a 240V wall outlet How much power in watts does it use?
The formula you are looking for is W = I x E. (W is watts, I is current in amps, E is volts) <<>> 5280 N
Answer At the service panel (breaker box) you'll need a double-pole breaker rated for the dryer (probably 30 amp) and run two "hot" wires (red & black) usin…g 10/3 w/ground cable. The neutral (white) and ground (bare) are just like standard 120V connections.
Answer for USA, Canada and countries running a 60 Hz supply service. First of all, you're asking this question in the right manner, since you are trying to get a 3 prong dryer… to work with a 4 prong outlet. 4 prong outlets were introduced with the 1996 electrical code to correct an old problem of people getting shocked by dryers connected to a 3 prong system, because the 3 prong had no grounding means. What you need to do is DONT EVER replace your 4 prong outlet with a 3 prong receptacle. Instead, replace the cord on your dryer with a 4 prong cord. It just may save the life of your wife. Also if you remove the plate over the electrical connections on the back of the dryer, there would be a metal bonding strip going from the middle wire of these old cords to the frame of the dryer. You absolutely need to remove this bonding strip, and then connect the 4th - green - wire of the new cord to the case instead. And as always if in doubt, contact an electrician. Number 1 safety tip of the day if you dont know what you are doing: whatever you do don't attempt to convert a 4 prong outlet to fit the cord on the dryer. Also don't listen to anyone who suggests it. A four blade dryer plug is the new code and should not be changed to a three blade cord. What should be done is to change the three blade receptacle to a four blade receptacle. The only difference in the receptacle wiring is that the position of the neutral wire and the addition of a ground wire being brought out to the dryer on a separate blade to match the ground wire on the plug. Shut the circuit to the dryer to the off position. Opening up the receptacle you will find now two hot wires to the outside blade sockets and a neutral to the center pin. Look in the back of the box and you will see a ground wire wrapped around a screw that grounds the dryer feed wire. From this ground wire add an extension of six inches. This new wire then connects to the fourth terminal on the new four blade receptacle. Looking at the new receptacle you should have the two hot wires on the outside terminals X and Y, white (neutral) to the L shaped W blade and the newly installed ground wire to the U shaped ground G blade. This receptacle is a NEMA 14-30R, 3 pole 4 wire grounding receptacle By asking this question you probably aren't quite ready to take on this particular task. For your safety and that of anyone who wants to use the appliance connected to that plug, hire a professional licensed electrician to advise you or do the work for you. Really, don't do this one yourself. 240 volts is far too dangerous to handle if don't yet know which prongs are which because you have not been trained how to do this work yet. To meet current wiring codes/regulations for your locality (Town/State) a new Ground wire or a Ground Fault Circuit Interrupter (GFCI) - to protect you as well as the dryer - may be legally necessary, for instance. If you put just one wire in the wrong place because you do not understand how to wire a 220-240 volt appliance correctly - which is clearly why you asked this question - you could easily kill yourself or someone else in your family, or even start a house fire. 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.
No. If we plug it It will work fine for some time after some time it starts getting heated and the plug gets heated up and it can lead to many dangers.
s for USA, Canada and countries using similar 60Hz mains supplies Conversion Dangerous and NOT RecommendedUmmm 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.
%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 With the 30 amp breaker you must have at least #10 wires feeding the circuit.
You can, but be advised that whatever you plug into the new outlet should not exceed 5000W capacity (20A x 250V = 5000W)or you could risk overheating the new outlet with seri…ous results. To prevent this, you should make sure the circuit breaker is a 20A also.
Answer . Don't understand this question. If the breaker is on, then the dryer would function normally, if the breaker your are referring to is the one for the dryer. If the… breaker is off then no function. A dryer runs on 220..
Answer You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit an…d put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.
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 hi…gher current, raising resistance.
240 volts require 2 poles on a panel - 120V each pole - so the answer on "how" is that you can't.
Why are electric stoves and clothes dryers supplied with 240v but light radios and clocks are supplied with 120v?
The loss of electrical energy in the wires that carry it to the appliance is proportional to the square of the current (Amps) in the wire. So, for example, a device th…at uses ten times as much power to do its job causes (10) 2 = 100 times as much to be lost in the wires. A clock radio uses perhaps 5 watts of power, a light bulb maybe 40 to 100 watts. An electric oven uses something like 3,000 watts when it's on, and a clothes dryer something like 4,500 watts. If the major appliances ran from the same supply as the small ones, then compared to a 100-watt incandescent light bulb, the electric oven would lose 900 times as much as the light bulb loses, before the power ever reaches the appliance to start doing its job, and the dryer would lose 2,000 times as much. Besides the unnecessary expense, the lost energy also heats the wires ! By supplying the power at higher voltage, the required current (Amps) decreases by half, and the loss in the wires decreases by 75% .
