Protect Against House Fire With AFCI Outlets
If you could upgrade your electrical outlets to protect against a house fire, would you? AFCI outlets protect against the leading cause of electrical fires in residential homes by shutting down the electricity to a circuit when an arc-fault is detected. Over 50% of electrical fires in the U.S. each year could be prevented with the installation of arc-fault protection devices, according to an estimate by the Consumer Product Safety Commission (CPSC).
What is an Arc-Fault?
An arc-fault occurs when an electrical current arcs outside the conductor without proper insulation. This flow of electricity can reach 5000 degrees F and ignite surrounding materials, sparking a house fire. Arc-faults are caused by loose electrical connections, damaged electrical cords or internal wiring including:
Nails driven through wiring in the walls
Furniture pressed up against cords
Cords pinched in doorways
Frequently bending and unbending chords (wrapping up a computer power cord)
Cords damaged by heat, sunlight, or humidity
Too many devices plugged into a single circuit
There are two types of arc faults, either of which can happen when there is damage to the wire insulation. Even a small break in insulation can create an arc. As the arc burns the surrounding insulation, the carbon from the burn acts as fuel until the insulation spontaneously combusts and starts a fire. A parallel arc fault occurs when current flows through damaged insulation from one conductor to another, creating a short circuit that is too weak to be detected by the circuit breaker. Series arc faults occur when a single wire is damaged and cannot withstand the current, causing the current to arc from the conductor into the insulation. This leaked current can burn and eventually ignite the insulation.
Protect Your Home with AFCI Devices
At first, AFCI protection was only available as a specialized circuit breaker and had to be installed by a licensed electrician. Now there’s a much less expensive option; for less than $30 each, you can install AFCI outlets in your home. Replacing just the first outlet in a branch circuit protects all of the downstream outlets, cords, and plugged in devices regardless of the wiring used from the panel board to the AFCI outlet. It also offers upstream protection against series arcs.
