Electricity is dangerous!

You can be injured or killed!

Improper installations can cause fire, injury and death!

Should you be doing this yourself?)

This is one of those questions - if you know this little, you shouldn't be doing what you are planning...

No disrespect intended, but this is SO basic that it suggests you have not studied the subject at all!

There are many good reference books and course books to study from.


This is one of the most commonly asked questions in FAQ forums about electricity and wiring.

It must be understood that new appliances will be designed to meet the newest standards.

It is not reasonable to expect someone to rewire their home because they need a new dryer or range [stove]!

According to the NEC [National Electrical Code], it is now required to isolate the neutral conductor from the appliance frame or chassis.

It used to be allowable to use the neutral as a grounding means by incorporating a

link between the neutral and the chassis.

The problem with this is that, should the neutral become "open" at some point, the chassis or frame then becomes energized!

The answer to this safety issue was to require a separate grounding conductor in the cable feeding the appliance.

The NEC allows the replacement of the new four prong cord with a three prong cord for appliance replacements in existing installations only!

It is then required, when the cord is thusly replaced, to establish the frame grounding link from the chassis to the neutral.

<><><> Turn off the power! Disconnect grounding strap (or green wire) from chassis of dryer that leads to the common on the wire block on the back of the dryer. Then wire as follows: Red and black wires to their respective hot terminals on block on dryer.

White to common lug on block of dryer. Green to grounding strap or wire that is connected to the chassis of dryer (no longer attached to common on the wiring block.







If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work


always use an electricians test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

It may be a 220 Dryer, and you will need a new outlet installed. There should be no extra wires when connecting the Power cord to the plug

Can you use an electric dryer with a gas dryer outlet?

A gas dryer burns gas to provide the heat needed to dry clothes. As it only needs a relatively small amount of electrical power to drive its motor, and maybe also a timer, the electrical socket outlet which a gas dryer plugs into need not be much different to a normal wall socket outlet. Any electric dryer uses a high-power electric heater, which takes a lot more current than is available from a normal socket outlet, so a special dryer socket outlet is needed to power an electric dryer safely.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 JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

How can I hook up my dryer in a regular outlet?

If there isn't a power outlet in reach of the unit you have two options. Call an electrician to install an outlet or call a carpenter to redesign your kitchen so that there is one near (basically move the dryer). Extension cables are not recommended for permanent use in kitchens.

Can a house outlet generate a 4 prong dryer cord?

Short answer: No A standard outlet is 120v and can safety provide about 15 amps. A dryer is 240v at about 30 amps. Also the typical 12-14 gauge wiring is not suitable to carry the current to power a dryer. If you did wire a dryer to a 120v plug most likely the dryer would work but provide very small amount of heat.

How can you convert a 240v clothes dryer to 120v can you use to different outlettes?

You cannot use 2-120v outlets to power a 240v dryer. You can convert a 240v dryer outlet to power 2-120v outlets if they are supplied with a neutral. This requires a competent electrician. Do not do this yourself.

How can you get a 20 foot long or longer 3 prong power cord for your clothes dryer?

As far as I know, you can't. It would be safer to have a new outlet installed closer to the dryer.

Can you plug two dryers into one outlet?

If the primary power source is gas you can. If it is a 100% electric dryer it need a dedicated circuit. If the primary power source is gas you can. If it is a 100% electric dryer it need a dedicated circuit.

A hair dryer uses 1.2 kW of power when it is plugged into a 120V outlet and is turned on What is the current taken by the hair dryer?

The formula you are looking for is I = W/E. W = kW x 1000.

An electric clothes dryer draws 22 A of current from a 240 V wall outlet How much power in watts does it use?

An electric clothes dryer demands 22A from a 240V outlet at approximately 90% Power Factor. The power demand on the outlet should be about 240V x 22A x 0.9 = 4.75 kW. The active components in an electric clothes dryer are the heating element (100% PF) and the electric motor that turns the tumbler (70-80% PF). The formula you are looking for is W = I x E. (W is watts, I is current in amps, E is volts)

Is it possible to hook up a 240V dryer to a 120V outlet via some sort of power converter?

No. You need to have a 220 outlet. Your 110 has only 1/2 the voltage you need. Also, the question you ask is not really feasible. The wattage required by the heating elements is more than what a 110V line could handle. (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. NO WAY One person has said "homes are not wired 110v, they are wired 220v. if you put a 2 pole breaker (or 2 pole fuse, if it's a fuse panel) in the panel, you will get 220v." Although it may be partly true, it does not answer the question. The related questions explore the amount of power needed for a dryer, which cannot usually be supplied through the wiring for a 110 V outlet. So, in general, the answer is no. You will need to run a different set of wires from the breaker/fuse panel to the location where the dryer is to be installed, and use a 2-pole breaker and the proper dryer outlet. You could, in theory, but the transformer would weigh more than the dryer and cost at least 4 times as much as a new dryer. The circuit would also have to be upgraded to at least a 60 amp 120volt outlet. Very impractical.

120V gas Kenmore dryer and the hook up location has the big 240V female receptacle--what is easiest solution thanks?

The easiest solution is to leave the 220V original outlet alone and plug the 110V dryer into a close 110V outlet, most likely the one for the washer. There should be nearby 110V outlets so you don't have to muck with rewiring the 220V outlet. A short heavy-duty extension cord is an option. I would also recommend killing the power to the old dryer outlet if it is unused. It cannot hurt. If you cannot plug the dryer into a nearby 110V outlet you can derate the 220V outlet down to a dedicated 110V outlet. This is not a task to be taken lightly if you are not experienced. If you do take this course of action yourself, buy a book. Do it right or don't do it at all. Negligence could kill someone.

Can a 50A dryer operate safely in a 30A outlet by simply changing the power cord to a 30A?

Can a fifty amp dryer operate on a thirty amp circuit if you change the cord? The answer should be obvious. It is a fifty amp dryer because it draws fifty amps.NO!The new dryer needs a fifty amp circuit!Call an electrician.

An electric clothes dryer draws 15 A of current from a 240V wall outlet How much power in watts does it use?

I have a stackable that plugs into the dryer but the 220 outlet and washer hookups are separate in my new home Is there an adapter that would allow for separate use of the washer in its own outlet?

If the dryer itself already includes a socket outlet that was designed to power a stackable washer then you should have no problem as long as the home's Dryer Circuit, and its breakers, can support the extra Kilowatts of power which the washer will take.To your question "Is there an adapter that would allow for separate use of the washer in its own outlet" the answer is No.Even if the stackable washer is mounted on top of the dryer it may still be possible to plug the washer into the existing, but separate, socket outlet that is intended to power a washer. If you cannot do that then it is best that you call in a licensed electrician to advise you.IF YOU NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER 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.

Can you run your generator 220v to the dryer 220v outlet?

It sounds like you want to use your 220 V outlet as a way to couple your generator to your house power in a power outage situation. Suggest you get an electrician involved and do it correctly with an approved transfer switch. Otherwise you are likely to burn your house down.

Why would the clothes dryer outlet heat up?

Loose connection, bad connection, they're are a few things that can be wrong. Shut the power down and open that up and check it out. The connection might be heating up. If that looks like the case, cut back and restripp the wires so you'll get a nice clean connection and install a new outlet. If everything looks good then consult an electrition because a dryer outlet can be a little warm but definately not hot.

Why does your dryer keep tripping the circuit breaker?

Either the circuit is too small to power the dryer or something else is drawing on the circuit that does not leave enough power to run dryer.
