I'm installing a 220 V outlet for my electric dryer. The outlet is
3-prong, and I have run 10-3 wire to the outlet. I know that the red
and black wires go to the two hot sides of the outlet, but which wire
goes to neutral? Is it the white wire or the ground wire (unsheathed)?
I have seen conflicting information online about this.
If it's the white wire i'm supposed to use, do I need to tie the ground
wire to the box the outlet is in?
Right. So which is it? Neutral or ground on the third terminal? I
would like to tie the ground to the outlet box at the very least, but
it's a bit difficult to work with the 10 gage wire. Is there an easy
way to do this, or should I just cap it off?
The point is that this IS a new installation and you should be using a four
wire outlet and cord set on the dryer. If it were an EXISTING feeder with
only three wires originating from a main service panel, your grounded
conductor would be connected at the panel to the ground/neutral bar and to
the ground/neutral connection on your outlet
If it is the NEUTRAL and not a GROUND, then it is the white wire. I
would tend to believe that if you have a three prong outlet that it does not
call for a neutral and everything in the dryer is 240V. The dryer would
only need the neutral if it had a need for 120V and they did not include a
transformer. It should always have a ground.
I would have to look at the wire diagram but I am pretty certain that
only the heating elements in the dryer are 240V. The motor, timer and
lamps are 120V. Therefore the third terminal should be a Neutral.
Maybe for the Irish, but in the US most dryers use 120 volt motors to turn
the drum and also for the timer.
The neutral wire also serves as the ground in the three wire hookup as it is
grounded back at the fuse/braker box.

If you are staying with the 3 wire plug the white goes to the
receptacle and the bare goes to the box or backstrap of the bakelite
device. Leave it a bit long so you can hook up a 4 prong receptacle
later if you want.
White goes to the neutral.
The bare wire goes to the (usually green) connection.
Sounds like you should really have someone in to look at this for you. You
could end up with a pretty dangerous situation if you miswire it and the
washer/dryer end up with a voltage between them. It's a longevity issue for
whoever uses them!
