What is an Arc Fault?
An ARC FAULT is an unintentional electrical discharge - a problem that even the most safety conscious homeowner can't always avoid. That's because arc faults are usually caused by undetected problems: Damaged extention cords, improperly installed wall receptacles, electrical cable pierced by picture hanging nails. Why is an Arc Fault dangerous?
An arc fault may ignite conbustible materials and cause a fire - a threat to any home and it's occupants. Furnaces in attics are common problems. What can I do to prevent Arc Faults?
You can't prevent arc faults from occuring. However, there is a device that can stop them - by interupting the electrical current before any damage is done. It's called the Arc Fault Circuit Interrupter (AFCI), and it electronically detects any arc fault and stops the flow of electricity in a fraction of a second. No electricity, no heat, no fire. And, by tripping on a specific circuit, the AFCI helps you identify the source of the problem right at the load center. Do fuses and circuit breakers serve the same purpose as AFCI's?
No. Fuses and circuit breakers cannot detect low level arcs. Only AFCI's are specifically designed for that purpose. Are AFCI's required by the National Electrical Code?
Yes. As of January 2002, arc fault circuit interruptors are required by the National Electrical Code on all new bedroom circuits. But, you can protect your existing home too ! By installing AFCI's now, you can get peace of mind from their added fire protection. more information
