Electrical behavior AFCI protects against electric fire due to electrical faults. There are two quite different types of arc faults. An AFCI ignores these normal arcs, but will detect the abnormal ones, using advanced technology. By cutting off power in a fraction of a second if a ground-fault is detected, Leviton Ground-Fault Circuit Interrupter (GFCI) GFCI receptacles and circuit breakers are engineered to help protect people from the hazards of electric shock and electrocution. This is one reason why Ground Fault Protection of Equipment (GFPE) is called for by certain parts of the NEC -- GFPE devices are like GFCIs, only with a higher trip threshold (30mA or 100mA vs. the 6-10mA of a GFCI), and are only seen in breaker form due to their limited scope of usage. A combination AFCI is an improved version of the original AFCI, and replaced it as a requirement in the 2008 edition of the National Electrical Code (NEC). . Just watch and learn as I say. These arcs can reach temperatures of 10,000 degrees F., hot enough to throw off sparks and ignite wood, fabric, and debris. It directly protects property by preventing a fire, and thus indirectly protects people. Beginning in 2008, the National Electric Code (NEC) has required the installation of combination-type ACFIs in all 15 and 20-amp circuits, with the exception of laundries, kitchens, bathroom, garages, and unfinished basementswhich are locations where Ground Fault Circuit Interrupter, also called GFCI, protection of the circuits is required. a parallel arc occurs when a small gap or break which permits current to flow to ground (a ground fault) or between the hot and neutral wires (a short circuit). Below are some conditions that can lead to an arc fault: Un-insulated wires (melted, damaged, overheated, or pierced through) Loose/improper connections The job of an AFCI device is to detect arc faults on an entire circuit or a single outlet rather than to detect ground faults. By doing so, these devices protect against fires caused by these faults. Where a receptacle outlet is supplied by a branch circuit that requires arc-fault ciruit interrupter protection as specified elsewhere in this Code, a replacement receptacle at this outlet shall be one of the following: A listed outlet branch circuit type arc-fault circuit interrupter receptacle.

A ground fault circuit interrupter (GFCI) can help prevent electrocution. 125-volt through 250-volt receptacles that are located within 6 feet (1829 mm) of the outside edge of a bathtub or shower stall and supplied by single-phase branch circuits rated 150 volts or less to ground shall have ground-fault circuit-interrupter protection for personnel. Definition of Arc Fault Circuit Interrupter or AFCI & Definition of Arcing Faults Arcing faults: a series arc occurs in electrical wiring when there is a small gap or break in a conductor. A GFCI device aims to detect anomalies in the flow of electricity and terminate the flow if it senses any danger. To find out what GFCIs and. A person who becomes part of a path for leakage current will be severely shocked or . GFCI: Ground-Faults - an unintentional electrical path between a power source and a grounded surface. Though both of the circuit breakers are important to have in households, there are distinct differences between arc fault and ground fault breakers. These devices come with test switches and they're quite easy to test. Arc fault circuit interrupters (AFCIs) can prevent many of the home electrical fires that kill and injure hundreds of people each year in the United States. About half of those fires can be traced to shorts, also known as arc faults, caused by electricity crossing a gap between frayed or broken wires and between loose or corroded connections in walls, appliances, and cords. As soon as the current flowing through the "hot" conductor is in the range of 4 to 6 milli-amperes more than the current flowing in the "return" grounded conductor, the GFCI senses this unbalance . AFCIs became a requirement for use in bedrooms based on the 1999 National Electrical Code which was effective in 2002. Arcing may be caused by damaged wires behind a wall or damaged cords that are plugged into an outlet. The AFCI performs the same action, but rather than a ground fault, what is detected is the arc fault. View More > How To Replace Or Troubleshoot An Arc Fault Circuit Breaker.
