How Do I Wire An Outlet From A 110v To 220? The 110 Outlet Having 4 Wires And A Ground. The 220outlet Has Only Three Including The Ground Wire.

HM,

There's much more than changing the outlet. You have to get an electrical permit. To do that you need to provide a written description and a wiring map to the LRA (Local Ruling Authority).

You will need to document The amperage of the proposed circuit, the AWG gauge of the conductors, the outlet, the faceplate and finally the device you want to place in use.

You can get most of the needed information right off the manufacturers metal tag on the device.

If your house is wired for 4 conductors, then you need to get the proper outlet and face plate. Is the device 3 wire or four?

Whatever wires, they need to be large enough for new load(#10 for 30Amp, #12 for 20 Amp for example)plus correct size ground and Neutral if Needed.
You CANNOT use a smaller wire than the Breaker will protect.
If a receptacle, it also needs to reidentified at both ends, then connect to your 2 pole breaker.

Strat,

That's why I asked the qestions>

This is a typical inexperienced DIY question.
There is MORE t it than "110" and "220". And there is more to it than "two wires" and "three wires".


HM,
What do you have existing?? Receptacle type, size and configuration?
What wires are existing?? What breaker is it on?
What do you want to install?? Receptacle type, size and configuration?
What are you plugging in to this new receptacle??

[Stratmando]

When enough information is not provided, I sometimes they have to correct what I say.
The poster also has to realize that 120 volt circuit is very likely with other 120 volt stuff and damage may result due to 240 volts, and will need to be capped and separated.

:eek: :eek:

GENTS _ THE way I read this is that he has a 110 volt circuit and wants to make it a 220 volt circuit, he probably has ( 4 0 wires because he has a countinued circuit that goes to another receptical that is 110 volt. :: Now if that is it , HE will have to pull new wire for the 220volt which will be 10/2 with a ground then he will have to pull new 12/2 with ground to the next in line receptical to get power back to it ( NOTE UNLESS THE POWER COMES INTO THAT RECEPTICAL THEN HE WILL HAVE TO MAKE IT DEAD AT THAT RECEPTICAL< AND STILL PULL THE 12/2 with ground to the next in line receptical. IF the hot comes from the main panel to the receptical you are trying to make 220 , then remove those wires in the panel . You will also have to install a double 30 breaker for the 220, and find another single 20 for the rest of the circuit you are leaveing as 110 . Good LUCK AND I HOPE THIS IS WHAT YOU WANTED TO DO <:: GOD BLESS :: F.B.E.::eek: :)

Now if that is it , HE will have to pull new wire for the 220volt which will be 10/2 with a ground ............... you will also have to install a double 30 breaker for the 220, and find another single 20 for the rest of the circuit you are leaveing as 110

I agree with what you are saying about pulling a new circuit and re-feeding the old, BUT, two things:

1) WHY bother re-feeding an existing receptacle box and mess about with pulling new feeds to the old circuit?? Just run a new 240v circuit to the desired location and LEAVE the existing one as it is.

2) WHERE are you getting that he needs 10/2 and a 30A breaker?? He never stated the amperage, and whether he needs a neutral or not.
That is very dangerous giving out wire size and type recommendations without knowing the load or circuit requirements.
What if this is for a 50A kiln?? Or an electric range? Or a stick welder?

Stanfortyman - #2- As per the way he posted his post ( He stated that he wanted to change the 110 volts TO 220 VOLTS< READ THE POST 1111 ) aLSO I STATED THAT IF THE FEED POWER WAS FROM THE PANEL TO THAT RECEPTICAL THAT HE WOULD HAVE TO RUN A NEW WIRE TO THE NEXT 110 VOLT CIRCUIT THAT IT WAS Originally TIED INTO .
#1- yES HE CAN DO THAT, iF HE WANTS TO KEEP THE OLD 110 VOLT CIRCUIT AND JUST RUN A NEW 220 VOLT CIRCUIT AND USE A REMODEL box FOR THE NEW 220 CIRCUIT, AND PULL 10/2 WITH GROUND TO THE NEW RECEPTICAL BOX , aND ALSO FOR THE NEW 220 HE WILL NEED TO put a double #) at the very least!! ::: F.B.E.

[stanfortyman]

........ PULL 10/2 WITH GROUND TO THE NEW RECEPTICAL....

I'll ask again.
WHERE are you getting that he needs 10/2 and a 30A breaker?? He never stated the amperage, and whether he needs a neutral or not.

HMSHARPE, is this a wall AC, and does it have a cord on it?
