We have a 220 outlet in what is now our shop. We would like to split it so we can use that outlet. This 'shop' was once a laundry room.

Thanks, Nancy

Hi Nancy. Do you know where the breaker is that feeds the 220 outlet? If so, can you tell me the amperage rating for the breaker? I also need to know if the 220 outlet was the only thing fed by the breaker.
Customer: replied 5 years ago.

Jason,

We have two breakers @ 30 amps each. Yes to 220 outlet fed by breaker.

 

Thanks Nancy

Thank you for asking your question on graphic

Thank you for the additional information. You will need to figure out which breaker feeds the outlet you want to convert. Remove the breaker and replace it with a single pole 20 amp breaker. You may need to buy a second single pole breaker to fill the other hole in the panel cover. There are also "filler plates" available for this purpose.

 

Connect the black wire for the circuit to the single pole 20 amp breaker. If there is a white wire connected to the old double pole breaker, remove it from the breaker and connect it to the neutral bar. If there is a red wire connected to the breaker, and the white wire is already on the neutral bar, remove the red wire from the breaker and cap it off at both ends.

 

At the other end, where the new 110 volt outlet goes, you will use black and white to feed the new outlet. Black goes to the gold screw, white to the silver screw. Don't forget to ground the outlet, if there is a ground wire in the circuit. If there isn't a ground wire, let me know.

My sweetie believes there is a ground but if not, what is our next step?

Thanks Nancy

Expert:  Jason replied 5 years ago.
Is there a red wire in the circuit?
Customer: replied 5 years ago.

Jason

There is only a black wire to the breaker.

Expert:  Jason replied 5 years ago.
Are you saying it's a single pole breaker? What was fed by the outlet you want to change? I assumed since it was formerly a laundry room, the 30 amp outlet was for a dryer. Is this not the case?
Customer: replied 5 years ago.
It was a laundry room. Yes it's a single pole breaker.
Expert:  Jason replied 5 years ago.
In that case, you should already be getting 110 volts from the circuit. Single pole breakers put out 110 volts. Double pole breakers put out 220 volts. Do you have a volt meter? If not, is there a voltage rating stamped on the outlet you want to change?
Customer: replied 5 years ago.
We have a 30 amp. And 125/250 volt.
Expert:  Jason replied 5 years ago.

That means it is at least a 3 wire outlet. In order to put out 125 and 250 volts, it would need 1 black, 1 red, and 1 white wire connected to it. If it has a 4th wire, that would be the ground wire.

 

Voltage from black to red would be 240 (250) volts.

 

Voltage from black to white OR red to white would be 125 volts.

 

It would require a double pole breaker to get 240 volts at the outlet.

 

Are you able to take a picture of the breaker and post it here?

Customer: replied 5 years ago.
We do not have the capabilities to sent a picture.
Expert:  Jason replied 5 years ago.
Have you removed the cover from the outlet yet? If not, please do so. I need to know how many wires are connected to the outlet, and what colors they are. Please be very careful not to touch any metal parts of the outlet when removing the cover. Thank you.
Customer: replied 5 years ago.
Black, white and ground
Expert:  Jason replied 5 years ago.
Okay, that could be either 120 volts or 250 volts. I assume you don't have a voltmeter. Do you see any numbers (other than voltage or amperage) on the outlet cover? If so, please post them here. If not, can you describe the slot configuration?
Customer: replied 5 years ago.

It is a 3 prong outlet. Bottom looks like an upside down L. At 2;00 flat slant. At 10:00 the same slant .

Expert:  Jason replied 5 years ago.

Is this it?

Customer: replied 5 years ago.
YES Sir.
Expert:  Jason replied 5 years ago.

I strongly suspect this outlet is wired for 220 volts, so there should be a double pole breaker in your panel with a white wire connected to it. The other wire on this breaker should be black. Have you removed the panel cover to look for such a breaker?

 

There are 2 options here to determine what needs to be done. You can buy a basic digital volt meter for about $20 and take a voltage reading from black to white.

 

Or, you can rig up a cord and do some testing at the outlet to determine whether it is wired for 220 volts. If you choose this option, let me know so I can give some instructions. Keep in mind that this is somewhat dangerous.
