Answer for USA, Canada and countries running a 60 Hz supply service.
White goes to neutral. White is an incorrect color for ground.
Upon further investigation you might find, however, that the white wire is connected to the casing of the appliance. If this is true and if this is the only function of the white wire then it is truly a ground wire. It should be wired as such to the outlet and it should be marked on both ends with green tape or paint or some other method of marking, or it should be replaced with a green or bare conductor.
If it serves the purpose of ground and neutral you may want to consider replacing the cable with a 4 conductor cable and isolate the neutral from the ground.

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.

How do you put on a four prong outlet on a roper electric dryer?
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
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.
Which prong of an outlet is live?
Looking at a duplex receptacle the right smaller slot is hot, the left larger slot is neutral and the u ground is ground.
Can you change outlet to fit old 3 prong outlet?
An old 2 hole receptacle can be changed to a 3 hole receptacle that will accept a 3 prong plug, provided a ground wire is available at the box and connected to the ground (green) lug on the new receptacle. A 2 hole receptacle has a hot and neutral wire, while a 3 hole receptacle will require a ground wire connection -- in addition to the hot and neutral wires.
Can you replace a 2 prong outlet with a 3 prong outlet if there is no ground line or is the ground required?
YES - it will work fine, and hopefully you have grounding in the plug. If you do not, you should also get surge protection and a safety cap when not using. The 3 prong will not create a ground, so it will not change the fact that it is dangerous not to have ground (you know kids and outlets).
How do you convert a 4 prong 240V outlet to a 3 prong 240V outlet?
Disregard the neutral

On a 240 volt outlet, such as a dryer outlet: G is Ground, W is Neutral, X and Y are the two Hot legs.
Can one convert a two prong outlet to a three prong outlet?
Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.

How do you test for groung on a two prong outlet?
Buy a tester. They are very cheap and will tell you at a glance if the outlets are wired correctly. The only other way is to remove the outlet and look see. But if it is a 2 prong outlet with no ground hole then it does not have a ground.

What is the function of the 'ground' prong?
Basically, Your ground prong is essential to protecting you from being in contact with an "unsuspecting Live current flow." It eliminates YOU as the primary grounding to whatever your plug is supplying power to, and sends any current flow, manually drawn (like touching it), into the ground prong. Your feet touching the earth acts as a "grounding" process, but with a ground prong; itself alone acts as the ground for you, allowing you to escape the ability to receive external power.
When wiring 4 prong plug for 220 has W X G and Y what goes into the X and Y?
On a 240 volt outlet, such as a dryer outlet: G is Ground, W is Neutral, X and Y are the two Hot legs.
Some tools dont have ground wire?
Some tools don't have ground wires because the tool exterior is plastic or some other material that will not conduct electricity. The ground is not required unless the case is metal and can become electrified if the "hot" wire touches it.Sometimes the tool's plug is "polarized" by having one contact larger than the other so it can only be inserted into an outlet in one direction, insuring that the same wire is always the ground or neutral and the other is always the "hot" wire. That insures that the tool's ground is always connected to the outlet ground.Other times the plug has a third prong that is the ground or neutral prong and can only be inserted one way in the outlet to insure the ground of the tool is always connected to the ground of the outlet.
