Converting 220V Receptacle to 110V

I am replacing an existing window airconditioner with a new unit -- the old unit was plugged into a dedicated 220V receptacle -- the new unit is 110V (smaller unit - 12000BTU). How can I convert the 220v receptacle to 110V?

Thanks for the help.

 

Before i can do that there are few things i need to know first.,,

what wire size you have in the exsting place now ?? if 12 gauge that will be no problem at all


if wire on 14 gauge it must stay with 15 amp breaker.

to change over from 240 v to 120 volts what you have to do in two steps before you get this done one is get correct repectale black on brass screw white wire on sliver screw and ground wire on green screw but you are not done yet go down to the breaker box take the cover off and you know which breaker for the A/C is then take the white wire off from that breaker and move it to netural lug and hook it up there

BUT IF RED WIRE STOP HERE We will give you little diffrent way to deal with it

Merci, Marc

 

Determine the size of the wire. The current breaker size can help with making an educated guess if not sure. Basically if the breaker is twenty amp and the wire is #12 or greater you replace the receptacle with either a 20a simplex or 15 or 20a amp duplex receptacle. At the panel you remove the white wire from the breaker and land it on the neutral.

If you have a 30a breaker it will need to be changed to 20a. If you have a 15a breaker and #14 wire you may not be able to use the existing circuit. It may not be enough for your AC.

 

The 220v circuit breaker is in a separate box with a feed off of the main (incoming) service (black and red) --- off of the (10A) 220v breaker are the black and white #12 wire with one bare copper ground -- these go to the 220V receptacle.

 

Sorry --- it is a 20A breaker --- so, if I remove the white wire from the breaker and hook it to the buss the bare copper ground is on, then I can hook up the 110v receptacle as normal?

 

20A breaker and #12 wire, yes you can do that.

 

Simie asked: "and hook it to the buss the bare copper ground is on, then ". If it is the main panel yes. If a subpanel then it lands on the isolated neutral.

 

Everyone ---- thanks for the help -- everything is working fine!
