You don't. There are only 3 wires in the box, while a 4 wire outlet requires 4 wires. All new wire would have to be pulled from the panel into the outlet box.
What should I do when I connect my 4-prong dryer to my outlet and it sparks?
I bought a new dryer with a four-prong cord. My husband changed the outlet also to be a four-prong. But I don't have a green wire in my wiring. What do I use for the green ground wire? Do I use just the black, white, and red?
The red wire on a 4 prong dryer plug has been cut. How do I wire it now?
What if the dryer still doesn't turn on after doing everything correctly?
I noticed that my three-prong dryer cord doesn't match my three-prong outlet. I have 10/2 WG wire to the outlet. Could I use a three-prong range cord to match that outlet?
I have a four plug cord and 4 plug wall socket except only 3 wires go to the wall plug. The dryer plug fits the wall plug but when running, arcing occurs from the supply lines. Is this safe to use?
