I need Circuit diagram to make 220v power point by using two 110v lines. Can any one do this for me.
Thanks

In typical residential wiring there are two 110V "poles" available. Each is 110V relative to neutral/ground, but they are out of phase with each other. In other words, as one pole swings positive, the other swings negative. Then, a half cycle later (1/120 of a second), the first one swings negative and the other goes positive. The net result is that there is a voltage difference between them of 220V.

So to answer your question, you just simply take a 110V line from each pole and you'll have 220V between them.

For a more specific answer, I'll need a little more information. Are you trying to get 220V in some location away from the breaker panel where you have two different 110V wires available? Also, is this something you need for a permanent application? If so you'll want to make sure both 110V wires are connected to the same 2-pole breaker so that if there's ever a fault, both breakers get tripped together.

Yes I need 220V point in kitchen, which is little away from the breaker. There are the sockets of 110v available in the kitchen, so I want to utilize these existing 110v lines in kitchen to make additional 220v point socket in same kitchen for using the electrical appliaces rated at 220vac.

Thanks

What amperage does the new outlet need to be?

What country are you located in?

Typical outlets are rated for 15 amps of current and are fed with 14-gauge wire. Sometimes outlets in kitchens are rated at 20 amps and fed with 12-gauge wire. Either way, if you successfully make a 220V circuit out of the existing outlets, you can't exceed the current rating for the wire in the walls (15 amps for 14 gauge, 20 amps for 12 gauge). A typical cooktop/range can draw 50 amps. If you try to draw that much current through your existing wires (and you up-sized the breaker in the box to allow it to happen), one of two things will happen: If you're lucky, the wires in the wall will vaporize and you won't have any power in the kitchen anymore. If you're unlucky, the wires will vaporize and set fire to your house as they go. Either way, as you can see, it's a very bad idea.

It's sounding more and more like you're going to have to run new wire from the breaker box to the kitchen.

I need 13Amps 220vac from two 110vac lines. Is is possible.

You really should leave the 110 volt circuits alone and install a new 220 volt circuit(s) for each 220 volt kitchen appliance.

My electric oven already does this connects two 110v to pull 220 and has done so reliably for 16 years without melting my house or any of the scary stories they are fond of telling - yes I've even run it on clean mode for 3 hours that goes to like 600 700 degrees and pulls full power doing it.

I agree with tkrussell, if you pull 2 x 110V become 220V supply for your kitchen, it will tripped both breakers. Better you install new 220V circuit for your kitchen (for safety reason).
