Running AC off of a Dryer Outlet


A friend of mine gave me an AC/Heater unit, and I have recently decided to add it to my garage. I live in Texas, so I will only be using the AC. The AC unit is a 20A 230v. My garage has my washer, dryer, and water heater in it. I need some way of powering the AC unit. I was wondering if there is any way that I can connect the unit to the Dryer outlet. I only have the 3 plug Nema 10-30 dryer plug, so I know there could be a problem with current coming through the ground. I also need to run the cord about 20 feet!! I had been given some very amateur advice to just get 25 feet of 10-3 wire from Lowe's and wire a dryer plug to one end and the AC plug to the other. This sounded simple enough, but I am scared to try it!!! Can anyone please help me!?!? It is sooooo hot in my garage!!!

The only way to do this right is a new circuit.

There would be nothing wrong with adding a cord and running the A/C 25 feet as long as you use the drier plug for both. This means unplug the drier and operate one at a time. You will be fine.

Running AC off of a Dryer Outlet


Do I need to do anything else to ground the AC unit? I think I read something in another thread about how 3 plug dryers have a ground to their frame because of the 125v running through the ground plug. I know that I can NOT use both at the same time, so I would be unplugging the one to put the other in. Are there any consequences to having the male dryer plug at one end of the extension cord and a female AC plug at the other? They are both 230v and they are both 3 prong, but they are not the same type of plug. I know I would obviously have to make sure I hooked up the corresponding wires at both ends.

Your neutral wire is were the 120 comes from. Hot to Hot is 220V Hot to Neutral is 120V. Your dryer now has a chassis to ground connection and your A/C probably does too. Just make up your extension cord with the proper plug on each end and use it. You will not have any problems.

You do know that you cannot legally use an extension cord for any type of appliance, now don't you? Legally, it would be considered unsafe, and only should be used for a short period such as 20 minutes if that.

Is that why electricians make up extension cords to run welders at construction sites everyday all day long. He uses it on a temp. basis.

Dryer is a 30 amp circuit. You can not legally install a 20 amp receptacle on it.
