AFCI breakers, or Arc-Fault-Circuit-Interrupter breakers, are commonly installed in newer homes. This video, taken at a recent home inspection in Oak Harbor on Whidbey Island, explains how to test these breakers for proper operation. The 2005 NEC stated that AFCIs must be placed on bedroom power and lighting circuits; new codes require AFCI breakers be installed for all rooms within the home supplying outlets. As with all property protection and life saving devices, the ultimate use, beyond the Code, rests with the homeowner. Smoke alarms, fire extinguishers and escape ladders are all examples of emergency equipment used in homes to take action when a fire occurs. An AFCI is a product that is designed to detect a wide range of arcing electrical faults to help reduce the electrical system from being an ignition source of a fire. Conventional overcurrent protective devices do not detect low level hazardous arcing currents that have the potential to initiate electrical fires. It is well known that electrical fires do exist and take many lives and damage or destroy significant amounts of property. Electrical fires can be a silent killer occurring in areas of the home that are hidden from view and early detection. The objective is to protect the circuit in a manner that will reduce its chances of being a source of an electrical fire. Below is a great link to some additional information about AFCI breakers.
