Electric dryer outlets are 30-amp, 240-volt receptacles that are designed specifically for electric dryer connections. A common mistake people make is to use a range cord, which has a totally different configuration. Range outlets are actually rated for 50 amps and feature two blades at a 45 degree angle and one straight blade for the ground connection.

This is quite different from the dryer outlet that has two blades at a 45 degree angle and an L-shaped blade for the ground connection. Because they are both 240-volt outlets, they both have two hot feeds.

Newer dryer outlets come standard with four connection points. Two are hot feeds, one is a neutral, and the other is a ground connection. This has two straight blades for the hot feeds, a blade bent like an "L" for the neutral, and a round blade for the ground connection. Do you know how to connect a dryer outlet?

In your description regarding how to wire a dryer receptacle, you say ‘red is right’ and ‘black is left’ on a 3-wire (+ ground) receptacle box. My dryer and receptacle is the opposite. Since red and black are both power wires, should your description not read that the red and black wires go on the sides (angled) not mattering which is which?

I am concerned that something might be haywire in my connections.

You’re right – as long as the ground and neutral are on the correct terminals, the red/black wires can be connected to either of the ‘hot’ terminals

We do not use the 220 dryer outlet, but need a 120 v 50 amp plug to service our motor home when it is at the house. Can an electrician use the dryer wiring and replace the outlet with the outlet we need stepping down the voltage? We would use a heavy extension cord to run limited service (35 amp AC) for the motor home.
