What are Arc Fault Circuit interrupters?
An arc fault circuit interrupter (AFCI) is an electrical device that detects arcing faults in household wiring and interrupts power before serious damage can occur.
Safety Features
AFCI's are safety devices that save lives and prevent fires.

In what areas do arcs tend to form?
Arcs may result when wires are incorrectly wired or their insulation is damaged. As it grows older, the wire insulation in older homes tends to crystallize, making it fragile and likely to crack or chip. If the insulation is harmed, the wire that carries an electric current is exposed to its surroundings, raising the probability of an arc occurring. Several situations may generate arcs, such as electrical cords that are damaged by vacuums or jammed beneath furniture and doors; nails or screws in walls puncturing wire insulation; heating of appliance cords along with natural aging, bending, impact, and stretching them out too much; fluid seeping out; and loose connections in outlets, light fixtures, and switches.
What is an ARC?
An arc, which is a glistening plasma discharge created by an electric flow that spans from an energized part to a grounded one, can be seen in lightning, a large, vigorous arc that traverses an atmospheric gap from one electrical cloud to either the ground or another cloud. Such arcs that arise out of home wiring may generate intense heat levels strong enough to provoke fires and with it destroy dwellings and life as reported by the National Fire Protection Agency in 2005, referencing 20,900 households being damaged by electrical fires resulting in 500 casualties and causing $862 million worth property damage. Studies expose that arcs are accountable for the majority of these cases; they are inconspicuous to conventional (non-AFCI) circuit breakers.
View DetailsWhere are AFCIs?
The places where it is necessary to install AFCIs depend on the local building regulations. The 2006 International Residential Code (IRC) requires that AFCIs be installed within bedrooms in the following manner: E3802.12 Arc-Fault Protection of Bedroom Outlets. Bedrooms with 120-volt, single-phase, 15- and 20-amp outlets require combination-type or branch/feeder-type circuit interrupters so that each of the branch circuits supplying them is guarded against arc faults. Exception: The location of the arc-fault circuit interrupter shall be permitted to be at other than the origination of the branch circuit, provided that: The arc-fault circuit interrupter is installed within 6 feet of the branch circuit overcurrent device as measured along the branch circuit conductors, and The circuit conductors between the branch circuit overcurrent device and the arc-fault circuit interrupter are installed in a metal raceway or a cable with metallic sheath. For Bedroom usage, the National Electrical Code (NEC) has made some suggestions with regard to AFCI placement: Dwelling Units. All 120-volt, single-phase branch circuits at 15 and 20 amperes. All 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets installed in a dwelling unit in family rooms, dining rooms, living rooms, parlors, libraries, dens, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter, combination-type installed to provide protection of the branch circuit.
Why were Arc-Fault-Circuit-interrupters introduced?
In response to Underwriters Laboratories’ (UL) U.S. Consumer Product Safety Commission report recognizing an electrical issue in branch circuit wiring systems that generated multiple residential fires, Arc Fault Circuit Interrupters (AFCIs) were developed. NEC® declared the utilization of AFCI breakers mandatory in 1999. In comparison to a standard circuit breaker, an AFCI breaker gives a greater level of protection by detecting and terminating a volatile arcing condition prior to it turning into an electrical fire.

How do Arch Faults work?
When a current-carrying conductor such as a wire or cable is broken, it produces heat that melts the metal into a pool of molten material called an arc. This creates a path of high resistance through the insulation on the wires, which causes the flow of electricity to be interrupted.
AFCIs requirements for Texas
TREC’s present assessment regulations stipulate that if a kitchen, family area, dining room, living space, parlor, library, study, bedroom, sunroom, recreational room, and corridor are not equipped with AFCI protection then it will be noted as a deficiency. Closets or washer-dryer areas must also come with this safety device. Yet, what does that leave you with? Practically nothing! To end on a takeaway note: all living spaces should have their own AFCI coverage This even applies to pre-existing dwellings. Now that this obligation has officially taken effect, multiple homes will appear on inspection reports with deficiencies simply due to the lack of AFCI safety devices.
When did Texas adopt AFCI's
1. On September 1, 2008, Texas began phasing in the requirement for AFCI’s in bedrooms.
2. On September 1, 2009, the statewide adoption of AFCIs became effective in all bedrooms.
4. In 2013, Texas required that all new residential dwelling units be equipped with approved circuit breakers and AFCI receptacles.
6. In 2018, the State Fire Marshal established a rule requiring AFCI protection for all existing dwelling units where circuit modifications or renovations take place.
7. On September 1st, 2020 the adoption of installation of AFCIs in all 120-volt, single-phase 15 and 20-amp branch circuits became code for existing dwelling units in various public building types.
8. As of September 1st, 2021 installation of AFCIs in one-family dwellings that underwent any type of alterations will become mandatory by the state fire marshall regulations as well as on commercial buildings as well.
