How do you get 120V from a single circuit breaker box that has a 240V line coming into the box that has one black one white and one bare line?
With a 2 wire + ground sized to the amperage that the load requires. From one lug on the breaker to the load, then from the second wire on the load back to the other lug on the breaker. Be sure to connect the ground at both ends, at the panel under the ground strip and at the load end under the ground screw. 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 you replace a 15 amp breaker in the circuit box?
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
How can you wire a normal 120V outlet out of a double pole circuit breaker?
well, the easy answer is, black wire to one pole of the breaker, white wire to the neutral bus with all the other white wires, bare wire to the ground bus with all the other bare (or green) wires. BUT the breaker must be 20 amps or less for residential outlets and you much match the wire size to the breaker, #14 for 15 amp breaker, #12 for a 20 amp breaker AND if there is only going to be one outlet, if it is a 20 amp circuit, the outlet has to be rated for 20 amps. Yes, but why would you want to? It is unclear to anybody else what you are doing and therefore a hazard. Do it right. Use a single pole breaker designed for 110V.
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.
Is it safe to have two black wires two white wires and two ground wires on a single breaker?
Hopefully just the black wires are on the breaker. Two circuits on one breaker. Shouldn't be a problem. It would depend on how many outlets or lights were on the breaker in total. Even then, there is very little chance of something drawing current from every outlet at the same time. The only thing is you can't put two wires under one breaker (by code). You would have to wire nut them with a pig-tail then just put the one wire under the breaker.
How do you pull 1 of 6 lights off a 3-way switch and add a single switch for that 1 fixture?
One 1,000 watt light will push a typical circuit breaker close to its limit. Six such lights will require wiring and circuit breakers to handle the load. Figure one circuit breaker per light. That means not only six switches but six switches, each on a different circuit breaker. Don't overload the wiring or it could cause a fire.

Where is the power windows circuit breaker on a 1983 280ZX?
Power Window Circuit BreakerI have a '83 280ZX and am also having power window problems. I was told by our local Nissan dealer service center, there is no fuse or circuit breaker for the power windows. There is a relay switch in the driver's door. None of my windows will let up or down. The switch cost is around $200. I am not sure about the '83 280zx, however on my '82 280zx there was a circuit breaker located in the passenger kick panel. You should see two screws above the fuse box which will remove a black unit that has the circuit breaker bolted onto it.(Just to verify) I also have a '83 280zx and yes thecircuit breaker is also located on the passenger kick.
What is the second function of circuit breaker?
The two functions a circuit breaker can do is protect the circuit from a high current short circuit and through its thermal trip it can protect the circuit from overload conditions. A circuit breaker will trip if too large a draw or current flow occurs across a thermal shunt inside, it can also have a ground fault circuit interrupter integrated internally in case of a difference in potential between neutral and ground resulting from voltage leakage from appliances or to protect against potential electrocutions A double circuit breaker provides access to the 2 legs of 120V in the back plane on the breaker panel. There are now typically 4 wires away from this breaker, a bare ground or earth ground, a white wire for neutral or bonded ground, a black wire for 1 leg of 120 and a red or blue wire for the 2nd leg of 120. You can use either leg and the white wire to access 120 or use the black and red/blue to access 240, white would then be used on the 3rd plug and ground goes to the ground lug or if missing it ties with the white and goes on the 3rd leg.
Do you need a 20 amp single or double pole breaker for your washer?
Washing machines in the U.S. operate on 120 volts. That requires a single pole 20 amp breaker and wired with 12/2 w-ground wire. Black to the breaker, white to the neutral bus bar, and copper ground to the ground bus bar.
How do I wire a 220 breaker correctly?
To wire a 220 breaker correctly, first turn off the power to the circuit. Connect the red and black wires to the breaker terminals, the white wire to the neutral bar, and the green or bare wire to the ground bar. Make sure all connections are secure and follow the manufacturer's instructions.
Why is the ground wire hot at all outlet boxes on a particular circuit?
Most likely the ground (green) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! Possibly you meant the neutral wire not the ground wire, in that case most likely the neutral (white) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! In either case check all three wires in the breaker panel for that circuit to make sure they are all correctly connected! Black is hot, White is neutral, Green (or uninsulated in some cases) is ground.
Can you only use white and black wires on a 2 pole breaker?
Typically the black wire is "hot", and the white wire is neutral. A 2 pole breaker is most commonly used for 240 V, and as such, you would typically use a 3 conductor wire, with black, red and white (+ ground). In a typical application, the black and red are used in the 2 pole breaker, and neutral is connected to the neutral bar in the breaker panel.
240V drop black red white bare on a 50A CB installed on the main power panel you want to split ths into two separate 120V circuits using the white as neutral for both will the 50A cb function normally?
It Will To The Exception That It Will Take Over 50 Amps To Kick The Breaker. You Will Have Two Circuits Protected By A Double Pole Breaker. You Could Remove The Strap On The Breaker That Holds The Two Together Giving You 25 Amps Per Circuit. ie One Breaker For The Black Wire And One For The Red Wire. Good Luck No, you will need to remove the double-pole breaker and install a separate breaker for each circuit, preferably no more than 20 A. The neutral and bare grounding wire can serve both circuits.
Is it safe to have two black wires two white wires and two ground wires on a single breaker?
Hopefully just the black wires are on the breaker. Two circuits on one breaker. Shouldn't be a problem. It would depend on how many outlets or lights were on the breaker in total. Even then, there is very little chance of something drawing current from every outlet at the same time. The only thing is you can't put two wires under one breaker (by code).
