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.
What gauge wire is needed to supply a 220v 50' 30amp service?
10 AWG.
How many wires does a straight 220V circuit have?
A straight 220V circuit utilizes two wires per circuit.
Can a 240v 50amp circuit be changed to a 120v 30amp circuit?
Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, a 240v 50amp circuit can be changed to a 120v 30amp circuit. The wire for the 50 amp circuit should be a #6. This is more than ample for a 30 amp circuit. Remove the two pole 60 amp breaker and replace it with a single pole 30 and a single pole 15 amp breaker. One of the two #6 wires will be terminated on the neutral bus (if there is a white use it) and the other #6 will be terminated on the new 30 amp breaker. This will give you the required 120 volt 30 amp circuit. The new 15 amp breaker that was installed just to fill the hole from the two pole 60 amp breaker will give you a spare 15 amp circuit. I have no idea what you are trying to do, but there is no way you can change 220v 50 amp to 120v 30 amp. You can take 220 volt input in the top of your circuit breaker box. Then half of one side will be 120v and half of the other side will be 120v. You can install a 30 amp fuse. You should hire an electrician.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

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.

What voltage feeds the coil on a shunt trip breaker?
220V
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.
You ran power from your house to your shop about a year ago The problem you are having is one of the bus legs in your shop panel box is not hot so every other 20 amp breaker is not hot on that leg?
Sounds as though you only ran a 110 volt power supply to your new shop subpanel. You need to supply 220V with a neutral and ground from your main panel to your subpanel. The 220 supply needs to come from a two pole 220V circuit breaker in your main panel. (example 50 or 100 Amp) Then, most importantly, you must use the correct size wire to carry the current. That is the wire must be sized correctly to the 220V breaker. The neutral must also be the same size as the conductors. Once you determine how much power you need in your shop, size the supply 220v circuit breaker and wire accordingly. Check with your local building department if you are unsure or what size wire to use with what size breaker or refer to Table 310-16 in the National Electric Code. In Australia domestic power is 240v So you have run single phase power to a three phase switchboard. To get power to those breakers you must hook the active to the busbar connected to those circuit breakers.
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.
