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

However, if you no longer want 220V at this fixture you can derate it to 110V. The key here is the current capacity of the old wire. You cannot exceede the current capacity of the wire as that is a fire hazard. Also the fixture must be on a dedicated circuit. You cannot mix 110 and 220, you have to derate the whole circuit. To derate:
- Get a 110V fixture of equal or lesser current to the old one that you want to use.
- Get a 110V appropriately sized for your fixture.
- Remove the 220V breaker and replace it with the 110V breaker. The white wire that went to the breaker now goes to your neutral bus.
- Replace the 220V fixture with the 120V.
Always, if you are not 100% sure of what you are doing, buy a book. It will answer your questions and serve as a handy reference during the job. Do it right or hire a professional. Negligence is fatal with electricity.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

∙ 18y agoThis is virtually impossible, as 210 is coming from the main fuse or breaker box from a 220 breaker or fuse. In order to do this you would have to start at the breaker or fuse box and rewire the breaker or fuse for the 110 outlet. otherwise this project will be impossible to complete without having risk of fire later. When 220 is run it is run alone and not intertwined with 110. 220 is double 110 output and will cause problems if not switched over to 110 properly. Use 110 wire and start at the breaker or fuse box. Most newer houses or electrical have breakers. Hope this helps. To do this correctly, you need to remove one of the hot wires and wrap both ends with white tape and reconnect it to the common strip in the panel.(220 is created by two 110 circuits out of phase) Replace the 220 outlet with a 110 outlet and wire it just like any 110 outlet. If you are lucky, the 220 outlet may already have 4 wires (2 hots, 1 common, 1 ground) in this case all you need to do is remove one hot and wire up the new 110 outlet. Insulate any bare wire and be sure the power is off before you start.

∙ 14y agoNo offense, but usually the people who ask this question don't know enough to do it safely. Your best bet is to hire a competent electrician. I know they cost money, but that's because they get the job done safely (or they should). That being said, if you would like to attempt this yourself, you should get yourself 2 references: National Electrical Code (whichever revision is in use in your locality, check with the office in your city that issues building permits)- This is essential to do any electrical work safely and properly, and you're going to want to do that. In most cases when installing an electrical panel, the power company will not connect (or reconnect) power to your new panel unless it has been approved by a local electrical inspector. Code Check Electrical- This handy guide is excellent for those unfamiliar with electrical work. It will specifically highlight commonly missed requirements for a code compliant installation. These are for sale at your local Home Depot or large bookstore. Whatever you do, when installing feeders from the meter base to the panel, do it properly by contacting the power company to disconnect your service. Too many do it yourselfers and even electricians have decided to install panel feeders by simply pulling out the meter to disconnect power. This will only disconnect power to one side of the meter. If the live side shorts, it will cause a fire and burn the power company's lines clean through. Please be safe and coordinate your panel installation with the local building authority and power company.

∙ 13y agoSimply use it. The 240 volt breaker is rated to be able to trip 120 volts with no problem. Of course, pick an appropriate current for the size of the conductors.
Naturally, if the 240 volt breaker is double pole, you have a problem, because that is not an expected configuration. Also, don't expect the reverse, i.e. a 120 volt breaker is not rated to trip 240 volts.

∙ 14y agoA circuit breaker is a device use in series with the load in many electrical application, residential, commercial end industrial. The power needs to be on in order for this protection device to function. A circuit breaker is in reality a mechanical device that can turn power off when an overload occurs, but a person has to tun it back on when the overload has been clear.

∙ 13y agoShut the main breaker off and use a battery light source to see what you are doing. After removing the panel cover you will be able to see what type of breakers are in the panel. There are two types, push-in or bolt-in. Shut the breaker you want to change-out to the off position. Remove the load wire from it. If the breaker is a push-in type, pry with moderate pressure in a direction to the side of the panel while lifting up on the breaker. If it is a bolt-in type just unscrew it from the bus bars. Install your new breaker: with a push-in breaker seat it firmly onto the bus with a hard push. With a bolt-in beaker a bit of caution should be taken not to cross-thread the screw into the bus. If this connection is not tight, arcing could result. Over time this connection could fail and may cause the panel to be changed out due to bus failure. Don't over torque the screw. Replace the load wire and cover and you are done.

All electrical work can be extremely dangerous if the person doing the work is not qualified.
The National Electrical Code defines a "qualified person" as "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."
For your own safety, call a qualified licensed electrician.

∙ 11y agoYou can just connect the black wire to one side of the breaker. Then connect the white wire you disconnected from the 240 volt breaker to neutral. I would recommend you remove the 240 volt breaker and install a 120 volt 20 amp breaker in it's place. Make sure to change out the 240 volt plug at the wall to a 120 volt outlet.

How do you replace a 15 amp breaker in the circuit box?
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.
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.
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 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.
How do you wire flood lights to existing lights?
You would need to check for other lights on the same circuit or switch, but it would seem to me that you have power coming into the box (black and white) and a power out going to another box or light. You would use wire nuts to connect the black and white wires from your floodlight to the existing ones.

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.

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.
