Incompatable 220v dryer plug with 110v outlet. Converter/transformer options?
Hey guys, I am trying to start up a used appliance business and I have run into the problem of plug/outlet compatibility. Electric dryers have 4 different types of power cords; two variations of 3 prong and two variations of 4 prong. Does anyone know of an adapter/transformer that would allow me to connect these 4 different plug types with my 110v home outlet to test the dryers out? If not are there any suggestions? Any help is much appreciated.

Welcome to the forums! You cannot run these appliances on 120 volt house current, period. You will need to run a dedicated 30 amp 240 volt circuit with properly sized wiring (I know it is different in Canada) to proper receptacles. If you have a shop situation where all is controlled, you may can pigtail between the different types of receptacles needed on one circuit. You cannot run more than one appliance at a time, that is why I say "controlled".

I have only known there to be two configurations for electric dryer receptacles, either a 3 wire or a 4 wire.
You are going to need 240 volts to test the dryers.

These are the different cord variants I was referring to. Chandler are you able to explain what you mean by "you may can pigtail between the different types of receptacles needed on one circuit"

The two plugs on the top are for a range/oven and are 50 amp circuits.
The bottom two are for a dryer and are 30 amp circuits.'
Both require 120/240 volts to work properly. I have seen a range operated without issues on a 30 amp circuit so, for testing purposes, I would suggest wiring a 30 amp circuit (or 50 if you choose) and then wire four receptacles, one for each configuration, all on the same circuit to plug in whatever configuration you need. An adapter(s) will cost you a lot more to build.

One issue you would have is that the ampacity will double when used on half the designed voltage. A dryer is 30 amps at 240 or would be 60 amps at 120 if it would even work.
A standard receptacle cannot be on a circuit greater than 20 amps.
