Can Dryer 220V plug be one sided as 110V plug


Just moved into a rental house and in the garage we are not using the 220 Volt dryer outlet. The outlets in the garage all seem to be 10 Amp circuits and these outlets will not start my small compressor but they will work with the circular saw though. The electrical panel for the house is at the other end of the house so there is no inexpensive way to add a circuit to the garage.

What I would like to do his use one leg of the 220 V circuit to power up a standard 110 V plug because the dryer is on a bigger amp circuit. Is a good idea or a bad idea? Are there any plugs already existing for doing this? (so far I haven't seen one) The only real issue I see is that there does not seem to be a third wire ground at the dryer outlet.

Thanks for the advice.

From what you are describing this sounds like a 3 bladed dryer outlet. If that's the case then you don't have a neutral, but you do have a ground wire. Regardless, no you can't do what you are describing. Your "little" compressor is probably bigger than you think, and a circular saw is nothing compared to the load of an air compressor. Can you re-wire the compressor motor to run on 220V?

The key word is " rental " that you should talk to your landlord first to see if they can allow that kind of modifaction or not.

And typically majorty of dryer circuits are 30 amp @ 240 volts so you compressour if reconferaged to 240 volts can be done HOWEVER .,, only if you have thermal protection on the motour itself. If none then you will have no choice but downgrade the breaker to either 15 or 20 amp two pole breaker.

Again talk to your landlord first before you do anything with it.

Merci,
Marc

Thanks for the info. I'll looking into the compressor rewire to check out how practical that might be. Either way I won't mess with the connector on the wall. Thanks again. Don

Not sure if it would be up to code, but you could get a small sub panel (one with like 4 circuits) and a dryer cord and wire up the panel using the cord. Then off the panel have a couple standard 15 amp outlets. It would be safe, as the breakers in the panel would protect the outlets (which are rated for 15 or 20 amps, but not 30) but not sure what code says about having a power cord connected to a panel. Maybe it's ok because it's considered a temporary use device. Ex: concerts and such most likely have setups like this that hook to a generator. This way you don't have to modify the rental's electrical.

I'd check with the landlord first though to see if he/she is willing to change it.

Don't forget that ground and neutral must not be interconnected within the portable subpanel assembly (think: power strip) and neutral must be connected to a plug neutral pin only. So this works only with 4 prong 240 volt receptacles..

How close is the garage to the kitchen? You could use an extension cord to plug into one of the 20-amp small appliance circuits.

There is no way its legal to hook up a sub-panel with a dryer cord... so kind of a moot point.

Oh I figured all dryer outlets had 4 pins. How do 3 pin ones work, no neutral? Then yeah that would not work.

Maybe they are all 4 pin in Canada...
3 wire dryer have two hots and a neutral; though the frame is grounded through the neutral. Some would say it is energized though the neutral.
They were not allowed after 1990, or something like that.

They have a neutral, they don't have a ground, the dryers frame gets re-bonded to the neutral connection inside the unit.


It would still technically work, you would re-bond the the neutral to the ground bar, just like at the first disconnect, this would be a violation though, but technically still work.
