To create this article, volunteer authors worked to edit and improve it over time. Learn more. March 28, Learn more Determine the maximum power that will be drawn on the new circuit.
Divide the total number of watts by or for a Volt circuit. The result is the maximum current, in amperes amps , for the circuit. Select the proper gauge conductor for the maximum current of the circuit. Select a 14 AWG conductor for a maximum current up to 15 amps. Select a 12 AWG conductor for a maximum current up to 20 amps. Select a 10 AWG conductor for a maximum current up to 30 amps.
Select an 8 AWG conductor for a maximum current up to 50 amps. Purchase the correct circuit breaker. You must use a circuit breaker that is approved for use in your service panel. In most cases, you must use a circuit breaker made by the same manufacturer as that of the service panel. Select a circuit breaker with a current rating that does not exceed the rating of the circuit.
For example, if a circuit is wired with a 12 AWG conductor, only use a circuit breaker rated for 20 amps or less. Run the electrical cable for the new circuit. Allow for sufficient cable at the service panel to route the cable to the entry point in the box and then from that point to the farthest destination in box. As a rule of thumb, allow for a length of cable that is 2 to 3 times the height of the box. Place a rubber mat or sheet of plywood or other dry wood in front of the service panel and stand on it while working in the panel.
Open the cover of the service panel and turn off the main breaker. Note the location of unused circuit breaker spaces in the service panel cover. You must install the new circuit breaker to line up with a pre-punched knockout in the cover. Measure the voltage to verify that the power is off in the service panel. Place one probe of a voltmeter on the neutral bus bar and place the other probe on the supply bus bar the bus bar to which the existing circuit breakers are attached.
If the voltmeter does not read 0, the power in the service panel is not off and you should not proceed. Choose the location in the service panel for the new circuit breaker. Remove the knockout. Use a hammer and screwdriver to bend the knockout. Grasp the edge of the knockout with pliers and bend it back and forth until it breaks loose. Locate a circular knockout on the top, side or bottom of the service panel box that is convenient for entry of the new circuit cable and for routing conductors inside the box to the new circuit breaker location.
For safety reasons, select a knockout that is not in close proximity to the live service wires that connect to the main circuit breaker. Install a cable clamp in the circular hole in the service panel box with the clamp on the outside of the box. Use a screwdriver to open the clamp as far as possible. Identify the location on the cable that will extend approximately 1 inch 2.
Strip off the outer jacket of the cable from this point to the end of the cable. Use a utility knife to carefully cut down the middle of the cable jacket. Peel the jacket apart and pull it off the conductors back to the point where you began your cut. Cut the jacket off with a utility knife. Remove the paper that surrounds the bare copper ground wire. Wrap electrical tape around the ends of the conductors to hold them together.
Route the conductors through the cable clamp until 1 inch 2. Tighten the cable clamp. Remove the electrical tape holding the conductor ends together. Determine whether your service panel has separate neutral and ground bus bars. Your service panel has separate neutral and ground bus bars if all of the white wires are routed to one bus bar and all of the bare or green ground wires are routed to another bus bar.
Your service panel does not have separate neutral and ground bus bars if the white and ground conductors are connected to only 1 bus bar. Route the ground conductor to the ground bus bar or common neutral bus bar, as applicable. Cut off any excess conductor with the wire cutter. Loosen a screw in the bus bar, insert the conductor through the hole and firmly tighten the screw.
Route the white wire to the neutral bus bar. Cut off any excess conductor. Loosen a screw in the bus bar, insert the wire in the hole under the screw and firmly tighten the screw. Determine how you will route the black wire to the location for the new circuit breaker. Loosen the screw on the circuit breaker and insert the end of the black wire under it and then firmly tighten the screw. If you are installing a double-pole breaker for a Volt circuit, connect the black wire to either screw connector on the circuit breaker and connect the red wire to the other screw connector.
Install the circuit breaker. Set the new breaker switch to the off position. Route the black wire that is connected to the breaker switch from the cable clamp to the location where you will install the breaker. Hold the circuit breaker at an angle and align its connection point with the rail, clip or slot in the service panel.
Press the other end of the circuit breaker into place. Some brands will click into place; others will not. To assure that the breaker is properly installed, verify that it is level with the adjacent circuit breakers. Test your installation by first turning on the main breaker in the service panel and then turning on the new circuit breaker.
Use a circuit tester or plug in an electrical appliance to test the new circuit. I want to install a 20 amp breaker on a garage circuit that is now 15 amps. Can I just replace the old circuit breaker so I can safely run my volt air compressor? The short answer is, probably not. The wires coming out of that breaker may not be thick enough to handle 20 amps and you risk fire.

Install a hot wire into the new breaker, and then line up the breaker into position and snap it into place. Punch out a blank on your breaker cover panel and install it.
Not Helpful 0 Helpful 2. You're mixing volts and amps which are two different things. In your circuit breaker box you should have two supply lines of V each. What you want to do is install something called a double pole circuit breaker which will connect to both supply bus bars. You'll need to run at least two hot wires and a ground wire to where your outlet will be, however depending on your appliance, you may also need a neutral wire. Word of caution because you're not clear of amps and volts: I think you may have a lot of research to do and strongly suggest coming back with specific questions regarding your plans before you do anything.

Your Circuit Breaker Box is Full — Now What?
Connecting a ground wire to a circuit breaker is not a difficult job, but you do need to administer care and attention to be entirely safe. Before you can run a wire to a new circuit breaker, you need to have sufficient room in the breaker box. As long as you do, you can turn off the power at the main breaker before beginning the task. Take the cover off the breaker box. Place one probe of a voltage tester against the neutral bus bar and the other probe against the bus for the terminals. If you register any voltage at all, the current is still on and you should check that the power is off at the house mains.
How To Correct Double Tapped Circuit Breakers
Installing a circuit breaker is sometimes considered the most intimidating part of home electrical work. In fact, most people choose not to do it themselves out of fear of being shocked. By understanding the layout of your electrical panel and taking adequate precautions during the installation process, you can safely install a circuit breaker in your home. To install a circuit breaker, start by turning off the power supply to the electrical panel and removing the cover over it. Make sure you use a test light or meter to verify that the power is off since it's dangerous to install a circuit breaker in a panel that still has power. Once you've verified that the power is off, find an unused space next to or between existing circuit breakers and press the new circuit breaker into the space, making sure the circuit breaker is in the "off" position beforehand. Finally, connect the circuit wiring to the electrical panel. To learn how to choose the right circuit breaker for your installation, scroll down!

Easy Generator to Home Hook Up
A generator is a core component to many people's emergency preparedness plans. Maybe you have a cool charcoal powered or a multi-fuel generator. However many fail to think through how exactly they will power the items they want to run when the grid is down. In June of my family experienced a 10 day power outage. It was eye opening. It was degrees during the day with periods of heavy rain. I had to run a sump pump to keep my basement dry, a refrigerator, freezer for food preservation, a portable AC unit in the living room to protect my infant, we charged phones, and ran the wifi router. I had power cords everywhere. It was a pain. I decided then and there I would find a better way.
