The two "hot wires" connect just as before. Both black wires will connect where the old black wires were. The white wire will go to neutral, just as before. The green, or Ground wire will connect to the frame of the dryer. Try to find a suitable ground point on the dryer to connect the green wire. Often you'll find a green screw that's intended for the green 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. 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 electricians test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

What if you have four wires running to your dryer outlet and the outlet is only a three prong one wire is just hanging out is this really even safe?

Have the outlet changed to match the configuration of the dryer plug.


Can you use a 120v cord that will fit a 240v socket the appliance is 240 and the cord is thick?

120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires, one neutral wire, and one ground wire. Therefore, if you changed the voltage from 120v to 240 using a 3 wire cord, you'd not have a ground wire and that could be VERY dangerous. Note that occasionally a 240v device (e.g. some motors) will only need three wires (red,black,green, no neutral) and can be wired with a 120v cord if the cord is rated for 240v.


Which colors are hot on a 4 prong dryer cord?

A four blade dryer plug cord should have a red, black, white, and green wire in the cord set. The red and black wires are the ones that deliver the 240 volts to the dryer. Black and white deliver control 120 volts to the dryer and also drive the motor to turn the dryer drum. On some dryers they use the red and white for the motor and black and white for the control. As for the green it is always the ground wire.


How do you change the plug on your clothes dryer cord from three prong to four?

You have to go buy a new four prong chord, unscrew the base of the old chord, and switch them out.


Is it possible to put a 4-prong plug on a dryer that uses a 3-prong plug and how would you do this?

If you are viweing this because you want to change the newer 4-prong plug/outlet to fit an older 3 prong outlet/plug don't do it! The newer plug is safer and the 3 prong plug no longer meets code. See the discussions in other threads. all you need to do is hook the two hot leads on the outer terminals, then the nueatral, white wire on the center terminal and the green ground wire to the ground screw. Be sure to remove the bonding jumper that ties the neutral to the chassis. This is no longer needed as now you have a ground line from the outlet. There should be 3 insulated lugs in the dryer, two hots and a neutral. Connect the red and black wires in your new cord to the hot lugs (red &amp; black are interchangeable), and the white neutral to the neutral lug. Neutral is the center wire on your older 3-wire cord, for reference. Connect the green ground wire directly to the chassis of the sryer using a convienent screw. Use the four prong cord if you can. It is safer because it has the extra ground wire which older cords did not.

How does one adapt a three pronged plug on a dryer to a electrical outlet with four holes?

You need to find an adapter.

How do you connect 3 wire to 2 wire 240volt's I'm trying to remove the washerdryer outlet and branch four 240v receptacles from the 240volt 3 wire outlet?

just leave the neutral wire as it is and connect the other two !!


Can you plug a three-prong dryer into a four-prong outlet or is there an adapter you should use?

You should install a four prong. The older ones were three prong and had no ground. An adaptor isn't made because it wouldn't fix the problem. You could make your own adaptor and cut the ground off with a pair of dykes, but don't.


How do you hook up 4 prong cord to 3 prong dryer?

To adapt a three prong range cord?&aelig;to a four prong outlet you need to remove the screws from the back plate to open the electric access panel. Then, pull out the copper grounding strip attached to the middle terminal. Next, remove the green ground screw from under the terminal block and attach it to the four prong outlet.?&aelig;


How do you put on a four prong outlet on a roper electric dryer?

Black &amp; Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.


What is the most cost efficient and quick way to fix the problem if you have a stove that has a four-prong cord and an outlet that only takes three prongs?

buy a 3 prong cord and plug set at lowes or home depot and change the cord on the appliance.


What is the difference between a 4 prong dryer outlet and a 4 prong stove outlet?

The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
