How To Install Eaton Breaker

Download Article

Installing a circuit breaker is sometimes considered the most intimidating part of dwelling electric work. In fact, near people choose not to do it themselves out of fear of beingness shocked. However, installing circuit breakers into most residential electric panels doesn't accept to be unsafe or overly complicated. By understanding the layout of your electrical console and taking adequate precautions during the installation process, you can safely install a circuit breaker in your dwelling house.

i
Plough off the ability supply to the electrical panel. Locate the Service Disconnect or Main excursion breaker in the panel and set up information technology to the "Off" position. This circuit breaker is likely to take the largest amp value and will be located either at the top or bottom of the panel.^[one]
- If yous don't see a circuit breaker labeled "Service Disconnect" or "Chief" in the console, it is likely in another panel in the edifice or in the meter socket enclosure (a split up, usually greyness box that houses the utilities meter for many houses and mobile homes and that is connected to various circuit breakers throughout one section of a building). Look for other panel(s) as needed until you find this main circuit breaker.
- Turn off all computers in your abode before switching off the power, as they may be damaged by of a sudden losing power.
2
Audit the circuit breaker arrangement for unused locations. Look for a blank area on the electrical console that could arrange a circuit breaker, paying detail attention to unused spaces at the tiptop and lesser of the cover. Some manufacturers of electrical panels have removable knockouts or plates at these locations, but the panel itself lacks provisions to mount a circuit breaker.^[2]
- If the unused location has a knockout plate over it, you'll have to eventually remove information technology before completing the installation process. For now, you lot merely need to place a infinite where you can install the circuit billow.

Remove the electric panel comprehend. Use a screwdriver to remove iii of the screws supporting the cover. Then, use 1 arm to hold the panel cover in place equally you unscrew the last screw. Finally, pull the cover away from the console.^[3]
- Exist certain to concord the panel comprehend tightly in identify every bit you remove the screws; if the cover slips and falls, it could harm the breaker handles.
- If you're unable to concord the panel cover in place with 1 manus, ask a friend to aid you.
iv
Exam the panel to make certain the power is off. Use a exam low-cal or meter set to check for the presence of power. Touch 1 probe to footing (the bar that has blank or light-green and white wires continued) or neutral (the bar that has just white or simply bare or green wires connected) and bear on the other probe to the spiral terminal of a circuit billow that has a black, red, or blue insulated wire connected. If 120 (or more) volts is indicated, the panel is still being powered and will need to be turned off earlier proceeding.^[four]
- Make sure your examination calorie-free is ready to the highest Air conditioning voltage range available (and is prepare at minimum to 120 volts).
- If the Service Disconnect or Chief excursion breaker is in this console, it will always indicate power on the terminals that take cables connected. The output of the Main or Service Disconnect when located in the console, connects to the bus bar. The bus bar should have no power present when this billow is OFF. Testing at the Service Disconnect or Main circuit billow is not recommended due to this "seemingly conflicting" information.
- It is not safe to install a circuit breaker in an electrical panel that still has power flowing to it. Practice not continue if power is present on a excursion breaker other than Service Disconnect or Main excursion billow, until the power source has been close off.
five
Find an unused space next to or between existing circuit breakers. The new circuit breaker yous install will demand to be placed side by side to a excursion breaker already in identify. Carefully compare this location to the encompass that was removed earlier to make sure it aligns with an unused location on the cover.^[5]
- Information technology's very important that the cover has provisions for exposing the new circuit breaker by removal of the knockout plate. If there'due south no plate to be removed, the circuit breaker will have to exist located in a different place on the panel.

Make sure you have the correct excursion billow. The panel label will list all the approved types of excursion breakers that can be installed in the panel. Deviating from the list is a lawmaking violation and voids whatsoever UL, FM or other list services' blessing. For maximum safety, apply but those circuit breakers that are allowed to be installed in the panel.^[vi]
- Typically, the simply breakers allowed to be installed are from the same manufacturer of the panel - fifty-fifty if other make breakers are labeled as "fits (brand proper noun hither) panels".
- The breaker should be of an ampacity that does not exceed the excursion conductor'due south rating. This is typically 15 amps for #14 copper, twenty amps for #12 copper and 30 amps for #10 copper conductors or wires. Consult the code volume to decide sizes for other circuits.
- The terminal size should be big plenty for the wire to fit. The demand to remove strands of wire to fit the final is an indication of an error somewhere along the line.

Set the circuit breaker handle to the OFF position. The excursion breaker has iii possible positions: ON and OFF and a mid position when TRIPPED. Push button the handle towards the OFF position before installing the breaker to ensure your own safety during the installation procedure.^[seven]
iii
Align the circuit breaker with the bars in the panel. Tilt the excursion breaker so that the hold-on prune on the bottom of the breaker is attached to the plastic "take hold of" bar in the panel. One time fastened, pivot the excursion billow on the mechanical contact and roll towards the middle of the panel - making sure the bus bar of the panel is still aligned with the slot or opening on the circuit breaker case.^[8]
- You lot may have to apply pressure to the billow for it to become attached to the plastic bar.
four
Firmly press on the circuit billow to seat it onto the bus bar. Apply your thumb to press firmly just gently on the circuit breaker until it snaps into place on the bus bar. Yous don't have to spiral the breaker into place; it's held in identify by bound clips and the panel cover.^[9]
- While information technology will require firm fifty-fifty pressure to exist seated, it should not have to exist forced.
5
Connect the circuit wiring to the electrical panel. Subsequently making sure the circuit billow is nonetheless in the OFF position, connect the white neutral wire and the black hot wire to the breaker. Loosen the spiral over the breaker'due south connexion terminal, insert the wires into the appropriate last locations, then tighten the spiral until snug.^[10]
- Your excursion breaker should have a label that indicates where to insert the neutral and hot wires.
- If yous're installing a double pole billow, you'll connect information technology to both the blackness and scarlet hot wires. Just brand sure you're using a switch that's designed to be used every bit a double billow.^[11]
- Note that at that place's no need to bend the terminate of the wire into a hook; it but needs to be straightly inserted into the connection concluding.

Remove knockout plates from your cover equally needed. Bring the cover up to the panel to compare the new excursion breaker location to the cover openings. Use a pair of pliers to remove any knockout plates on the comprehend location where the excursion breaker will be located.^[12]
- To remove the knockout plate, simply grip with the pliers and move the metal back and forth until it comes away.
2

Make clean all foreign objects out of the panel and reinstall the cover. Remove any tools, wire scraps, or other foreign objects that could cause a brusk circuit from the interior of the panel. Then, place the cover on the panel to check that the circuit breaker has fully been seated at both contact points and fits through the encompass. Finally, rescrew the cover onto the panel.^[thirteen]
3
Turn on the chief breaker and exam your new circuit breaker. Continuing to the side of the panel, restore power to the panel past setting the Service Disconnect or Chief to "On" and then set the new circuit breaker to "On". Cheque for correct functioning of the new circuit (low-cal, outlet, etc.) with a test light or meter.^[xiv]
- Clear any short circuit earlier attempting a reset if circuit breaker instantly trips.
four

Label the circuit billow. Locate the panel's excursion directory on the within of the console door. Determine the circuit breaker location (or "circuit number") and write a description of the circuit (load type such as "refrigerator" or a location such as "living room") in the space provided. Exist sure to edit the directory if whatsoever circuits were moved to install the new circuit.^[15]

Voltage levels as niggling as 50 volts can be lethal under the right weather condition. Most residential electric systems are 2 to v times this value. Shut off power whenever working on circuits and never proceed if unsure or uncomfortable performing the steps above.
Always stand to the side of an electrical panel when turning circuit breakers "on". The amount of energy being transferred is directly proportional to the amperage value rating on the circuit breaker. While a single pole 15 or 20 amp brusk circuit would probably not cause catastrophic damage, a double pole 100 or 200 amp brusque circuit certainly could. Standing off to the side takes a person largely (though not completely) "out of harms fashion".
Never install a circuit breaker into a panel for which it was not designed. Many circuit breakers will physically fit into different panels, however simply those identified on the panel'south characterization are approved for use. Using improper circuit breaker causes forfeiture of UL, Factory Mutual and all other "listings". Use of unlisted devices is a code violation and in farthermost cases, may outcome in denial of a claim to the insurance company in the event of a loss.
Prior to using any tester or meter, exist sure it works past first checking on a known live circuit. If the device fails to indicate properly, practise not utilize until repaired or replaced.
In the US, 120/240 systems (the blazon nearly often constitute in a residence or dwelling) apply a colour lawmaking for wiring; Black, Reddish, Blue "hot wires" and White neutral wires. In add-on to 120/240 volt systems that announced in residences, many commercial and industrial settings likewise accept 277/480 systems. These higher voltage systems utilise a different color scheme to immediately alarm the electrician of the higher voltage panel. The color scheme used for these systems is Brown, Orange, Xanthous (think "Male child") "hot wires" and Gray neutral wires. Be sure new wiring is installed in the right panel.
