WHAT IS AN ARC FAULT CIRCUIT INTERRUPTER?
Thunderstorms are capable of producing rain, thunder, and lightning. Lightning can create electrical overloads in the home wiring system, which can then cause electrical damage to appliances and electronics. But, even when these devices are unplugged, an electrical problem might be within the walls.
One device which has become a game-changer to prevent arcs is an Arc Fault Circuit Interrupter or AFCI.
What is an arc?
An arc occurs when electricity flows through a damaged electrical system, causing an electrical current through the air. Most arcs are harmless. But, if an electrical system has damage, such as a loose wire, an arc can create a temperature of over five thousand degrees, and start a fire without tripping a conventional breaker at all.
Differences between an AFCI and a GFCI
An Arc Fault Circuit Interrupter, or AFCI, is designed to shut down the outlet or other designated wiring if heat is detected. A Ground Fault Circuit Interrupter (GFCI) is intended to avoid shock hazards, which protects people. An AFCI is designed to prevent fire hazards, which protects property. It does this by de-energizing the circuit, thereby lessening the effects of an arc.
Types of AFCI's
There are several versions of AFCI's, including an outlet AFCI, one designed to be used for a circuit breaker, a portable variety, and some combination types. Also, AFCI's are naturally a GFCI, because they interrupt the electrical flow. Some AFCIs also have an indicator to show when they've tripped because of an arc fault or ground fault, which can be useful to the electrician during troubleshooting after the event.
Arcing faults are the primary cause of over 30,000 electrical home fires each year. An AFCI responds to an electrical arc by shutting down the breaker or outlet. A typical arc is caused by aged, corroded, or faulty wiring. An arcing also commonly occurs as the result of a heat appliance such as an iron, toaster, or portable heater.
A growing trend
The National Electrical Code now requires AFCI devices to be installed for use in all bedrooms and sleeping areas (such as rooms with a fold-out couch). This safety measure is especially important because while people are asleep, they can easily succumb to smoke inhalation without ever having a chance to wake up.
Who can benefit?
Anyone can benefit from an AFCI in a home with older wiring. They are also especially useful in homes with those who have reduced mobility, such as seniors and the disabled. Children's bedrooms are another location to add an AFCI. If a business regularly operates a heat-type appliance, that location can also benefit. Eventually, the use of AFCI's will expand to more areas where the potential for a wiring mishap is a concern.
Future technology
New safety devices are now being developed rapidly to protect more lives and property. While we take electricity for granted, we must never lose sight of the fact that electrocution and fire are still severe threats and treat them as such. We must take the long view of these dangers since a small electrical problem can have an enormous impact. Even homes outfitted with AFCI's and GFCI's should still have fully functioning smoke detectors.
If you have concerns about the wiring in your home or business and want to install GFCI's or AFCI's, let us know. Each person can make an impact with a small amount of prevention.
