Electricians chime in please - 240V wiring mistake?

[factorytuned2012]

Yes, the wire coming from the breaker to the receptacle is 10/2 Romex, with black, white, and bare ground. On the receptacle, ground and neutral are bonded via a bare copper jumper wire. (Wiring was not done by me)

On the receptacle I sent, you would install the white and black on both hot lugs being the white is a hot conductor in your situation just identify the white with black or red electricians tape. The bare copper goes on the center pin shaped like L this is considered the neutral back when your wiring was current code. Its what is considered your “Grounded” conductor.

Roger that.

I would contact an electrician. It's not a complicated job to change out the box you have and install a 3 prong 30 amp box. Then on the new dryer install a 3 wire 30 amp cord and make sure the neutral and ground are connected on your new dryer. (On your old dryer you will see the grounding strap connecting to the neutral.) Very important. Have an electrician look at your sub panel as well to make sure it's wired up correctly as well.

The only thing in an electric dryer running on 240v is the heating element. Everything else is on 120v like the drive motor, drum light and mechanical timer motors. E boards use 120v as supply. I can't tell you how many blown up new dryers and ranges I've seen due to delivery man hook up screw ups miswiring pigtails with a hot leg on the neutral. White or neutral is vital for 120v supply, green ground is for safety.
