The plug-on-neutral breaker is a type of breaker you can connect directly to your neutral bar, thus negating the need for a pigtail connection. It’s almost the same as typical AFCI
Arc-fault circuit interrupter
An Arc Fault Circuit Interrupter (AFCI) is a type of duplex receptacle or circuit breaker that breaks the circuit when it detects a dangerous electrical arc in order to prevent electrical fires.
Residual-current device
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock.
What is the function of the neutral wire in a plug?
More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel . This gives currents circulation through your electrical system, which allows electricity to be fully utilized. Additionally, this prevents faulty or excess currents from residing in your outlet.
What happens if fuse is connected to neutral wire?
The current flows in excess, but the circuit doesn’t disconnect. The same may happen if the fuse is connected to neutral. Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral. But, a circuit can complete or obtain a conduction pathway either by the neutral or earth.
Does circuit breaker have a neutral?
The white neutral wires are not protected by a circuit breaker as it is only necessary to interrupt a circuit at one point to break current flow. That takes care of heat build up from overloads in wiring. The other safety consideration is that of voltage isolation.
Is the Black Wire in a plug live or neutral?
The black wire is the hot wire. Likewise, how do you tell which wire is hot and which is neutral? Most likely the neutral wire is white and the hot wire is red or black, but test to make sure. Identify the neutral wire in the fixture by looking at the wires. In most modern fixtures the neutral wire will be white and the hot wire is red or black.

What does plug on neutral load center mean?
With the electrical contractor in mind, Eaton has revolutionized the way combination AFCIs are installed with the plug-on neutral line of loadcenters and breakers. This unique product solution enables the contractor to connect the breaker directly to the neutral bar, eliminating the need for wiring a pigtail.
Are plug on neutral breakers different?
The Plug-On Neutral breakers will not have a pigtail, and will have a rejection feature on the bottom to restrict them to only Plug-On Neutral panels. The Non Plug-On Neutral breakers will have a pigtail and will not have the rejection feature.

What is a panel plug?
A panel mount receptacle enables you to plug connectors directly into a device wall or free-hanging connector for in-the-field assembly. The process involves cutting a hole in the surface of the electrical device and placing the receptacle through or against the hole.
Can ground and neutral be on same bar?
The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.
Why do some breakers have a neutral wire?
The reason that one of the power wires is named “neutral” is because it is connected directly to the building ground connection at the circuit breaker panel. Therefore it is connected directly to the grounding (third) wire.
Why do some breakers have pigtails?
Historically, AFCI and GFCI breakers needed a pigtail wire to get neutral. Some installers found that messy. So some newest panels do a positioning trick with the neutral bus so the breaker can clip onto it also. This is called "Plug-on neutral".
What is a dual function breaker?
What is a dual function circuit breaker? A technology combined in one device. The dual-function circuit breaker combines class A 5mA GFCI and combination type AFCI, protecting against both arc faults and ground faults.
Why do GFCI breakers have pigtails?
The white “pigtail” wire on a GFCI circuit breaker serves two functions. It completes the connection to the panel neutral bar for the neutral load conductor and also completes the power supply circuit for the electronics.
Can I use regular breakers on a plug on neutral panel?
Plug-On Neutral panels are available in the “Homeline” and the “QO” lines, and both panels will work with the traditional breakers as well.
Why are neutral and ground connected in panel?
Without the grounding wire, that misdirected electricity could shock you. At the main service panel, the neutral and grounding wires connect together and to a grounding electrode, such as a metal ground rod, which is there to handle unusual pulses of energy, such as a lightning strike.
Where is the neutral bar in a breaker box?
Neutral Bus Bar: A circuit conductor that carries the current back to the source. It is connected to the ground at the main electrical panel or meter and again at the transformer of the supply. The neutral wires will be white within the breaker box.
Can I use regular breakers in a plug on neutral panel?
A plug-on-neutral breaker panel is also compatible with standard circuit breakers. So even if you don't use special AFCI or GFCI breakers on all your circuits or want to reuse your old circuit breakers with pigtails, you're free to do so.
Why do some breakers have pigtails?
Historically, AFCI and GFCI breakers needed a pigtail wire to get neutral. Some installers found that messy. So some newest panels do a positioning trick with the neutral bus so the breaker can clip onto it also. This is called "Plug-on neutral".
Will a QOT breaker fit in a QO panel?
The QOT tandem breakers can ONLY be installed in the QO load centers that are designed to accept the QOT Tandem breakers. The QOT tandem breakers CANNOT be installed in the PoN QO load centers (See FA130326 to determine if a QO Load Center accepts QOT(CTL type) tandems.
How do you install a neutral AFCI breaker?
Here's how to install it:Cut the power to the breaker then remove the panel's cover with a screwdriver. ... Remove the old circuit breaker (if there's one). ... Locate the load center neutral bar and slide the new AFCI breaker in place. ... Attach the white and white to the breaker and the ground wire to the ground bar.More items...•

Does Square D have neutral load center?
When I leave a job, it’s a given that everything needs to work properly, but I also take pride that my installs look like they were completed by a pro. So I was pretty pumped when I found out that Square D created the Plug-On Neutral Load Center, which accepts Plug-On Neutral breakers that don’t require the extra pigtail wire. They’re installed just like regular breakers, so no more messy panels—yay!
Do plug on neutral panels work with a homeline?
Plug-On Neutral panels are available in the “Homeline” and the “QO” lines, and both panels will work with the traditional breakers as well. I recently got a chance to install the Homeline version. And yes, I know that nobody will see my handiwork until another breaker is added or replaced. But still, it was nice walking away from that job with an organized panel that looks like an electrician who actually gives a dang installed it. Just like the good ole days.
What is plug on neutral?
The idea is to provide a neutral bar at a fixed distance on each side of the bus bars, so specially-designed AFCI or GFCI breakers can plug directly onto the bus bar and the neutral bar without requiring a pigtail connection. Here's a picture from a catalog:
What are the extra long breakers in the middle?
The extra-long breakers in the middle are the AFCI ones which snap directly onto the neutral bar. Very clever!
Can GFCI breakers plug directly into bus bars?
The idea is to provide a neutral bar at a fixed distance on each side of the bus bars, so specially-designed AFCI or GFCI breakers can plug directly onto the bus bar and the neutral bar without requiring a pigtail connection. Here's a picture from a catalog:
Can you remove the bonding strap from a neutral?
Here is the location of the bonding strap that links the two neutral bars. It could likely be removed if so desired, but those two should stay linked and be tied with that strap to neutral so that the plug on neutral AF CI and GFCI breakers can operate properly.
Can you use #6 as a subpanel?
To use this as a subpanel you would have to buy a seperate ground block and grounding lug with enough spaces for your circuits or maybe two that could be combined with #6 or #8 bare copper. Then your bare stranded ground would connect to this new ground block and your neutral wire would connect to the lug where the bare stranded ground was connected before. If you remove the bonding strap then you loose neutral on breaker function for one side of the panel thus rendering any AFCI breakers on the affected side nonfunction for Arc Fault.
