Help! Rewiring 3 prong to 4 prong cord
 
I am currently rewiring my dryer with a 4 prong cord to the 3 prong connections. The Washer does not have a metal bonding strap, yet has the green wire running from the neutral to the frame. I am aware that this is where I need to connect the new green ground wire, but what to do with the existing green I am getting conflicting stories.

There are MANY different instructions on how to perform this on this page alone and the entire internet. I have also talked to Lowe's and Home depot electricians and got 2 different answers. "That should do it" is not good enough!" They all seem logical, I just need to know which answer is safe and will keep me alive. Here are the answers I have received so far.

  1. Connect the green wire currently attached from the neutral to the frame back to the neutral connection.
  2. Leave the green wire on the frame, just add the ground wire.
  3. Remove the green wire completely, cut it off/cap it.
Can I get some votes on to which is real? This site and many images on the net support all 3 of them. Can I get an expert opinion?

Cap it or otherwise eliminate the connection. I would not cut it off, you may use it again in the future. Perhaps some electrical tape, and a nice little zip-tie to secure it out of the way.

In the first sentence of your post, you are changing a 4-wire dryer to a 3-wire.

But the bold type caption at the top of your message suggests the opposite.

The instructions you have seen so far appear to be conflicting, because your message is conflicting as well.


So which is it? :huh:

"I am currently rewiring my dryer with a 4 prong cord to the 3 prong connections."

Looks like you overlooked the words "cord" and "connections". connections being the 3 on the dryer to suit the original cord, 4 prong being the new cord. Thanks for the input...

I also saw THIS on your original message:

OK, if you are attempting to install a 4-wire cord on a new dryer that apparently has 3 connections here is the procedure:

Look for a jumper wire connected from a green screw to the white terminal. This wire needs to be removed, isolated, or taped off. Either #1 or #3 of the previous answers you posted would be appropriate.

You now have 3 main terminals, and a 4th green screw terminal. Connect each of the respective wires to their corresponding colored terminals.





Answer #2 listed is incorrect, and creates a second (downstream) bonding connection of the neutral and grounding conductors. This can create an unsafe condition and the person who offered those instructions needs to be educated as to the proper procedures and protocols of dryer and range appliance connections.

The post below is actually directly from this site. There is conflicting information here as 'Stubbie' says "take that green wire coming from the dryer and connect it under the external ground screw with the green wire of the dryer cord". however below the diagram states to remove the green wire. The diagram looks as if it is the oposite.

Ill make sure to talk to the guy from L*we's who said #2 'Should be my best bet"

Thanks for the advice. You will have saved me at least $3.75 by tomorrow. Possibly my life?

In simple terms you do not have any green wires connected to the neutral terminal on a 4 -wire dryer cord connection. You only have the neutral to case bond on 3 wire dryer connections.

In your case ( 4 wire dryer cord) take that green wire coming from the dryer and connect it under the external ground screw with the green wire of the dryer cord. It will look like the below diagram.

This is 4 wire connection, not a 3 wire connection. There is no confusion. You can see this circuit has H-H-N-G. This is the way you would connect your appliance if you had 3 wires and a ground in the RECEPTACLE. You do not have 3 wires and one ground in your receptacle box. This is the way it should be installed. The only reason you get a pass on the 3 wire is because it already exists. If you were installing this circuit you would have to wire exactly like above.
