You may need a magnifying glass to read it.
What is AFCI in a fault?
The AFCI was thef first generation protection and detected one type of arcs. The combination AFCI added the detection for a different type of fault.
What is a combination type AFCI?
The Combination Type AFCI differs from the Branch/Feeder AFCI in its ability to detect series arcing faults. The Branch/Feeder AFCI can only detect line-to-neutral and line-to-ground arcing faults. Combination AFCIs provide protection against the high-energy parallel (line-to-neutral and line-to-ground) arcing and low-energy series arcing. “Combination” does NOT mean an AFCI + GFCI. Combination = parallel + series arcing. Combination AFCIs protect downstream branch circuit wiring, cord sets, and power supply cords.

Does AFCI breaker recognize series arcing?
But AFCI breakers did not recognize series arcing (between a small gap or frayed area in the same wire), so the combo-AFCI or CAFCI was developed, which has that additional capability. Beginning in 2008, the National Electric Code (NEC) has required the installation of combination-type ACFIs in all 15 and 20-amp circuits, ...
Where can I find AFCI breaker?
AFCIs are available through electrical distributors and in many home centers and hardware stores nationally. The only major physical requirement is that the AFCI breaker requires directly wired hot and neutral wires on the circuit you’re going to protect.
Why do I need AFCI protection on all 15 and 20A circuits?
Just like placing locks on all external doors and windows for security reason, it is logical to request AFCI protection on all 15 and 20A branch circuits, not just those in the bedroom, to protect the entire home from an electrical arcing ignition hazard.
What is an AFCI fire alarm?
An AFCI is a product that is designed to detect a wide range of arcing electrical faults to help reduce the electrical system from being an ignition source of a fire. Conventional overcurrent protective devices do not detect low level hazardous arcing currents that have the potential to initiate electrical fires. It is well known that electrical fires do exist and take many lives and damage or destroy significant amounts of property. Electrical fires can be a silent killer occurring in areas of the home that are hidden from view and early detection. The objective is to protect the circuit in a manner that will reduce its chances of being a source of an electrical fire.
Why are AFCIs used?
AFCIs were developed in response to an identified electrical problem causing fires in the home as noted by the Consumer Product Safety Commission and other prominent organizations. An AFCI breaker provides a higher level of protection than a standard circuit breaker by detecting and removing the hazardous arcing condition before it becomes a fire hazard.
What is an arc fault circuit interrupter?
Arc Fault Circuit Interrupters (AFCIs) are required by the National Electrical Code for certain electrical circuits in the home. Below are some frequently asked questions about AFCIs and the benefits of installing them in your home.
How does arc fault detection work?
How does arc fault detection work? In essence, the detection is accomplished by the use of advanced electronic technology to monitor the circuit for the presence of “normal” and “dangerous” arcing conditions. Some equipment in the home, such as a motor driven vacuum cleaner or furnace motor, naturally creates arcs. This is considered to be a normal arcing condition. Another normal arcing condition that can sometimes be seen is when a light switch is turned off and the opening of the contacts creates an arc.
What temperature does an arc burn?
The temperatures of these arcs can exceed 10,000 degrees Fahrenheit.
What is an AFCI circuit breaker?
AFCI circuit breakers include a standard inverse-time circuit breaker but provide no specific protection against glowing connections also known as a high resistance connection, high line voltages or low line voltages. An AFCI does not detect high line voltage due to an open neutral in a multiwire branch circuit.
What is an AFCI breaker?
The electronics inside an AFCI breaker detect electrical current alternating at characteristic frequencies, usually around 100 kHz, known to be associated with wire arcing, which are sustained for more than a few milliseconds. A combination AFCI breaker provides protection against parallel arcing (line to neutral), series arcing (a loose, broken, or otherwise high resistance segment in a single line), ground arcing (from line or neutral to ground), overload protection and short circuit protection. The AFCI will open the circuit if dangerous arcing is detected.
What is an AFCI receptacle?
AFCI receptacles are an alternative solution to AFCI breakers. These receptacles are designed to address the dangers associated with both types of potentially hazardous arcing: parallel and series. AFCI receptacles offer the benefit of localized test and reset with such buttons located on the face of the device.
What is AFCI in electrical?
Starting with the 1999 version of the National Electrical Code in the United States, and the 2002 version of the Canadian Electrical Code in Canada, the national codes require AFCIs in all circuits that feed outlets in bedrooms of dwelling units. As of the 2014 NEC, AFCI protection is required on all branch circuits supplying outlets or devices installed in dwelling unit kitchens, along with the 2008 NEC additions of family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, laundry areas, and similar rooms and areas. They are also required in dormitory units. This requirement may be accomplished by using a "combination type" breaker—a specific kind of circuit-breaker defined by UL 1699—in the breaker panel that provides combined arc-fault and overcurrent protection or by using an AFCI receptacle for modifications/extensions, as replacement receptacles or in new construction, at the first outlet on the branch. Not all U.S. jurisdictions have adopted the NEC's AFCI requirements so it is important to check local code requirements.
What is the NEC requirement for 2008?
The 2008 NEC requires the installation of combination-type AFCIs in all 15 and 20 ampere residential circuits with the exception of laundries, kitchens, bathrooms, garages, and unfinished basements, though many of these require GFCI protection.
What is the yellow label on a breaker?
This AFCI (the circuit breaker with the yellow label) is an older generation AFCI circuit breaker. The current (as of 2013) devices are referred to as "combination type."
Why are AFCIs used?
AFCIs are designed to protect against fires caused by electrical arc faults. While the sensitivity of the AFCIs helps in the detection of arc faults, these breakers can also indicate false positives by identifying normal circuit behaviors as arc faults. For instance, lightning strikes provide voltage and current profiles that resemble arc faults, and vacuum cleaners and some laser printers trip AFCIs. This nuisance tripping reduces the overall effectiveness of AFCIs. Research into advancements in this area is being pursued.
