How do you install a 120v 240v dryer in a 110v 220v home?

Answer 1

You don't. A dryer is manufactured to run on 240 volts. By trying to run it in 120 volts the heating element will not get hot enough to dry the clothes. A typical dryer needs a 30 amp breaker at 240 volts equals 7200 watts. A step up transformer (120 to 240 volts ) rated at 7.2 Kw will cost as much as a new dryer. To run the dryer thuough the transformer the primary voltage of 120 volts would draw a current of 60 amps. A normal houshold receptacle has a capacity of 15 amps. The wire size for the primary connection to the transformer would be # 4 wire rated at 65 amps

Luckily you're talking about a very simple machine that requires power for a heating element and a motor to rotate the drying cylinder. Any 2:1 transformer that can carry the POWER (Volts X Amps) will do the job. In today's global market, just about any respectable electrical store should be able to provide your needs in a simple stream-lined module.

Your dryer will have a plate that tells you it draws "X"amps. If it draws 10Amps at 220volts it is CONSUMING 2200 Watts (or 2.2Kw; 2.2 kilowatts). With this information your electrical retailer SHOULD be able to provide you with the appropriate STEPDOWN transformer.

• 1] TURN OFF THE BREAKER [or other power source] ... usually a 2-pole 30-amp breaker or fused disconnect switch
• 2] Unplug your dryer
• 3] Pull the dryer out and look where the present cord set enters the dryer through a connector
• 4] Get a new cord set - exactly like your old one [probably a NEMA 10-30P plug if three prong or NEMA 14-30P plug if four prong]
• 5] Get the tools that fit the fasteners you confront
• 6] Remove the old cord set
• 7] Install the new cord set just like the old one was installed
• 8] Close it up
• 9] Plug it in
• 10] Turn the breaker or disconnect switch back on

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.

Answer 3

You don't! The higher voltage could likely start a fire.

Otherwise you must have a transformer to change the voltage of the outlet to 110v, then plug the appliance into that. The transformer must be rated at the proper wattage. If you are taking a US appliance overseas to a country that has 220v you can usually find the heavy duty Transformers there. The plugs are shaped differently to prevent plugging into the wrong voltage system. It is not terribly difficult to add a 110v outlet. Take a standard duplex receptacle and break the link on the side between the two gold screws so you have the top and bottom operating separately. Put one hot on the top gold screw and the other hot on the bottom gold screw and put neutral on the silver screw. You will have 110v on both top and bottom. Do yourself a favor and turn the circuit off before you start. If you wire-nut 12ga wire onto the existing wire you will have an easier time than trying to make the heavy gage wire go on the screws. Remember that if you put 12ga in the circuit you will need to downgrade the circuit breakers to 20 amp. 14ga: 15 amp. The dryer circuit breakers are likely side-by-side in the box and may be linked together. You can take that link off because you don't gain anything by having both circuits pop at the same time once you have split them at the outlet. Also, make certain that you have a good ground. Since you are (presumably) close to the washing machine, you ought to put GFCI breakers in.

Answer 4

To wire a 110v outlet to 220v the 220v source must have a neutral conductor that is 110v away from the hot leg. If you don't have the neutral, you must provide a new circuit. Do notjust connect ground to the neutral terminal, as ground is not intended to carry current.

Answer 5

You can NOT do that. Both the box and the actual outlet are different. Further, it is against any electrical code I have ever seen. -Your only option is to get a qualified electrician to run a new, heavier wire and install the proper box and outlet for 220.

Answer 6

Answer for USA, Canada and countries running a 60 Hz supply service.

Please read this explanation thoroughly twice before doing any electrical work. Do this electrical work only if you feel confident that you can do it safely. If not, then this is the procedure that an electrician would use and you would be able to follow what he is doing. Again an electrician should be your first choice.

If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU.

Before an explanation of how to do this, you should keep in mind that this is for a single receptacle only, rated at 15 amps at 240 volts. It can only be a 15 amp receptacle because of the existing house circuit wiring is probably a #14 wire that is only rated at 15 amps. If any other receptacles are on the same circuit they also will also be changed to 240 volts.

That said OK, any 120 volt outlet can be changed to 240 volt. Remove the distribution panel's cover plate. Locate the white wire from the circuit that you are going to change and remove the white wire from the neutral bus bar. Remove the black wire from the single pole breaker that feeds the circuit that you are going to change. Remove the single pole breaker from the breaker panel. Install the new two pole common handle 15 amp breaker into two adjacent spare panel slots.

If you have no spare slots, use the hole left by the old single pole breaker. At this point you will have to relocate an adjacent breaker to make a space for the two pole breaker. Move the single adjacent breaker to a spare slot if you can find one. If there are no spare slots, stop the project, as the project will get complicated and you should leave it to an electrician. It has to do with load balancing.

If you are continuing, leave the new two pole breaker turned off. Connect the black wire that came off of the single pole breaker on to the top terminal of the new two pole breaker. Connect the white wire that came off of the neutral bar to the lower terminal of the two pole breaker. Install a piece of black electrician's tape for an identification marker on the old neutral wire.

You may have to remove one of the blank twist out covers that was in the position that covered the spare slot to accommodate the new two pole breaker. Re install the distribution panel's cover plate to the electrical panel, this end is finished. At the receptacle end remove the 120 volt receptacle and replace it with the new 240 volt 15 amp rated receptacle. Connect the existing two wires to the new 240 volt receptacle and connect the ground wire to the green terminal screw.

Materials can be purchased at local building supply store. Remember to take the electrical panel data with you so you have the information for the new two pole 15 amp breaker.

Once you have the receptacle installed, identify on the electrical panel door what the new breaker is used for. Turn the main breaker back on. Turn the new two pole 15 amp breaker on. Test the new receptacle with a voltage tester to make sure you have 240 volts and that every thing is OK.

Note; to be compliant with the electrical code, black tape both ends of the old neutral wire to identify it as a "hot" current carrying conductor and not to be mistaken for a neutral wire.

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.

Answer 7

In residential service 110, 115, 117, 120, and 125V are functionally the same. 220, 230, 240, and 250V are also all functionally the same.

Answer 8

Yes you can. Don't worry it won't break! I have tried it myself!

Answer 9

There is no difference between a 240 volt and 220 volt device. Both voltages are within the nominal voltage range of 230 volts.
