By asking this question you are probably not quite ready to take on this particular task. You may or may not get lucky and receive some information in an answer here! If you hope to get enough information on this site to be able to do this job properly and safely, please do not rely on getting accurate information about such a potentially dangerous subject. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you put just one wire in the wrong place you risk being killed by electrocution or you could even start a house fire.
How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact locations of some of the outlets you wish to install. If they are anywhere subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you don't want to go to your local library or bookstore - to find and read some books about electrical wiring and appliances and how to install them safely, and to find out about your local Wiring Codes and Regulations - then the best advice anyone should give to you is to call a licensed electrician either to do the job for you or to advise you what you may be allowed to do yourself. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator
to insure the circuit is, in fact, de-energized.

How do I get 220 volt circuit?
If you need a 220v circuit at only 15 or 20 amps: Get a new breaker to replace your 110v single pole breaker with a 220v double pole breaker. (You cannot exceed the original breaker's amperage rating unless you also replace the wire with a larger size). Shut off the panel's main breaker (the wires coming into the main breaker will remain hot, so don't touch them.) Remove the old 110v circuit's neutral (white) from the neutral bus bar in your distribution panel. Remove the old 110v circuit's hot (black) from the old 110v breaker. Remove the old 110v breaker. Install the new 220v breaker in place of the old breaker. (This may require you to rearrange some breakers if the old breaker was in between others) Reconnect the black wire to one terminal of the 220v breaker, and reconnect the white wire to the other terminal. Turn on the main breaker, and your new 220v breaker. Before you do this, be sure where the actual circuit goes. Changing 110v to 220v if the circuit is feeding regular 110v receptacles will cause damage to devices plugged into them. Be sure you remove all 110v devices (receptacles) from the circuit before converting it. If you need a 220v circuit for a dryer or other large appliance, your existing wiring will not be sufficient to do the above. You will need to install a new breaker and wiring. For this task, you should consult a professional electrician.
What size wire and circuit breaker is needed for an electric oven 4 wires with rated load of 34.9 amps 220v that is about 100 foot run from the electrical panel?
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
How many wires does a straight 220V circuit have?
A straight 220V circuit utilizes two wires per circuit.
Why do you convert 120v circuits to 220v circuits?
You would need to change a circuits voltage if your adding a load that requires 220 when the present circuit supplies 120. If you need to do so it's pretty simple! First purchase a double pole breaker at the proper amp rating. Next find the breaker in the panel that supplies power to the circuit you wish to change to 220. Turn off the breaker and pull it out. Find the neutral for that circuit. Then double check and make sure it's the right neutral. Then check one more time. Now take the neutral and the hot wire for that circuit and connect them to the double pole breaker. install the breaker into the panel and turn it on. If you connected the right neutral you'll have 220 on that circuit. If you didn't you'll know because you'll trip the breaker.
Can I add a circuit breaker wired in parrell to a current breaker to reduce the load on the breaker?
No, add new breaker,find a junction box and split the series, or add a box and split the load. You only need to do this if the breaker is tripping from overload. 12ga wire should have a 20amp breaker not a 15amp. If I understand your question,wired in parallel, this would be one hot connected to two breakers, first off two breakers is 220v not 120v , and 220v has two hot wires. Never connect two breakers together on one line.

Can a 2-pole circuit breaker be used for 110V 220V or 440V?
All three, on 110V a split receptacle, on 220V a baseboard heater, on 440V a construction heater or similar resistive load.
How many wires does a straight 220V circuit have?
A straight 220V circuit utilizes two wires per circuit.
Can you wire two 220V devices off of one 50A GFCI breaker where the total load is 38A?
No, only one GFCI per circuit.
What happens when both 110v leads are applied to one side of a 220v electric motor?
The breaker will blow because you are effectively causing a short circuit.

Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
Where do you use double pole circuit breakers?
For 220v circuits
How do you tap into a 220v feed going to baseboard heater and get a 110v supply?
This is only valid in parts of the work using 110/220 Volt split phase power system. There will be 110V from each of the hot leads to ground/neutral, so connect your outlet to only one of the hot leads, the neutral lead and the earth ground lead. This may be a problem with a dedicated 220V circuit as there will likely be no neutral line. Another note - this could well cause an unbalanced electrical load across the two pole breaker. If the breaker has a rating of 20A and the 110V circuit draws much of that current, the heater will likely trip the breaker.
