arc fault circuit interrupter protection has been required for dwelling units by the National Electrical Code for several years the new 2014 code expands the area specified for protection as well as allowing more options to provide arc fault protection for a branch circuit an arc fault is an unintended arc created by current flowing through an unplanned path arcing creates excessive heat that can easily ignite surrounding material such as wood framing or insulation resulting in a hazardous situation arc faults are often unseen and can occur for a number of reasons including damaged extension or appliance cords often pressed up against furniture or under carpets nails staples and screws inadvertently driven into wires inside the walls cracked worn or damaged wires or cords caused by environmental conditions aging or even rodents poor connections caused by loose terminal screws on receptacles and switches art faults are often referred to as series or parallel arcs a series arc occurs in one conductor and is a low level of current which is in series with and limited by the load it is often the result of a bent or broken wire a parallel ARCA 200 conductors and is a higher level of current because it is in parallel with and therefore not limited by the load it can occur when nails or staples are driven through wires historically the NEC requires arc fault protected circuits in areas such as bedrooms family rooms dining rooms hallways and closets in the 2014 NEC the requirement for arc fault protection is expanded into kitchens and laundry areas additionally the code will now require afcis and dormitories so let's discuss the various installation methods for new residential construction allowable by the 2014 any C code to 10.12 a and to 1012 B for protecting a circuit using arc fault technology a combination type AFCI breaker this is the most common and most complete way to provide AFCI protection it is installed at the panel and safely detects both parallel and series arcs in the entire branch circuit including the home run circuit and downstream out through the connected cords branch feeder AFCI breaker with outlet branch circuit AFCI receptacle this is a branch feeder type AFCI breaker installed in the panel with an AFCI receptacle installed at the first outlet box on the branch circuit this method protects the entire circuit from the source and allows local reset capabilities however it requires to AFCI devices that can be costly supplemental arc protection breaker with an OBC AFCI receptacle this method allows for a listed supplemental arc protection circuit breaker to be installed at the origin of the branch circuit in combination with a listed AFCI receptacle installed the first outlet box on the branch circuit while this allows for local reset capabilities supplemental art protection breakers are not currently available additionally there are limitations in the home run length and the circuit must be continuous system combination AFC I thermal mag breaker with an OBC AFC i receptacle a listed tested pair that includes an OBC AFC I receptacle installed at the first outlet on the branch circuit in combination with a listed branch circuit over current protective device installed at the panel while this installation allows for local reset capabilities tested and listed combinations of AFC I receptacles and upstream branch breakers are not currently available additionally there are limitations in the home run length metal conduit or armored cable to the first AFCI receptacle this installation requires metal conduit from the panel to the first AFCI receptacle in a circuit this allows for local reset capabilities but installation of conduit can be costly and impractical in many applications however this may be the most practical application for dormitories hotels or other commercial applications and finally the code also allows the use of conduit in concrete with a FCI receptacle this method allows for metal or nonmetallic conduit or tubing to be encased and not less than two inches of concrete for the portion of the branch circuit between the panel and the first AFCI receptacle in a circuit this method has limited applications and can be costly it's clear arc fault protection saves lives by mitigating arcing that could be an ignition source of a fire as you can see there are many allowable installation methods for AFCI protection before moving forward with an installation or project which requires AFCI protection know your local code requirements in addition to the NEC methods it's important to consider the application and then choose the best installation method to provide the preferred form of protection for further information visit Eaton calm /a FCI

  1. 3:46 If the electrical code is gonna make you spend a fortune on arc-fault protection, why not just use armored cable and metal boxes for all your wiring instead of those unreliable arc fault nuisance trippers?

  2. Is the idea for replacing the first outlet in the circuit with an AFCI outlet that the wiring between the panel and the AFCI must be well-protected? Hence, MC cable, in conduit, encased in concrete, etc.? Unless there in an AFCI breaker in the panel?
    Basically, if I replace the first outlet in the circuit with the AFCI outlet, do I also need to change out the raceway going to that outlet?

  3. Here we go again!! Another AFCI breaker after a year, now giving me trouble!! It was an existing 2 wire circuit ( NO shared neutral) but remodeled beginning of 2017 requiring a dual GFI / AFCI braker. It's a microwave circuit dedicated circuit. New microwave as of Jan 2017. Breaker worked until last week, started getting calls that it keeps tripping. I"m going there tomorrow to try and explain this nightmare to another good client. AFCI breaker, I hate you!!
    EAtON, you can make all the videos you want, but bottom line, these things suck!! They are not dependable!!

  4. Another way for the product manufacturers to FUCK PEOPLE OVER. Forcing you to have this on ALL NEW HOMES. NEC SUCK DICK & DIE

  5. I understand the concept of the AFCIs, and they're well needed with today's homes. However, trying to explain to a customer that has an outdated panel and little cash, that they need $1000+ alone in parts for a new panel since they're required by code now on almost every circuit, is absolutely insane and makes a lot of customers keep their old outdated unsafe panels. Huge difference in $4 breakers, vs $40-$50 each.
