Questions about: Installing a Washer Dryer Unit with an Existing Dryer Plug


  1. Mark S. says:

    I have a combination washer / dryer (over and under) unit that has a NEMA 14-30 plug on it. The house I’m moving into has a NEMA 10-30R socket in the wall. My question is, can I change out the socket to a NEMA 14-30 so that I can leave the washer/dryer in tact? this is the only plug on it and powers both the washer and the dryer. The breaker for this outlet is a 30 amp – double pole breaker. Wire guage is unknown at this time….

    • Dave Rongey says:

      Hi Mark,
      The issue is that the NEMA 10-30 is a 3-wire outlet, and the washer/dryer has a 4-wire cord. IF this washer/dryer manual states that a 3-wire cord may be installed then that would be the solution, but I think you may find that the unit requires a separate neutral wire therefore you could only install a NEMA 14-30 IF there were a unused neutral wire with the existing 30 amp circuit, and that could only be known by turning the circuit OFF and removing the existing outlet.

    Hello, I do have concerns regarding my 4 prong dryer outlet its because my kids keep messing with the power of the dryer. I just wanted to put a 20 or 30 amp off switch on it, is it possible? I was confused because of the 4 wire, and which wire will go to the switch then to the outlet, 2 of those were + ,neutral, white and ground, the live wire were red and black.
    Thanks.

    • Dave Rongey says:

      Hi Ramel,
      If you were to install an On/OFF switch, then the switch would need to be rated for the dryer circuit, such as the Leviton 3032-2, which is rated for 30 amps 240 volts. The switch would be a 2-pole switch and it would have to be installed into a switch box enclosure that is grounded. The 240 volt circuit wires would be attached to the switch.
      Another consideration is to install a 30 amp non-fused disconnect which would accomplish the same thing. Keep in mind that either way, the switch or disconnect must be located in an accessible location.
