What is an AFCI?
AFCI is an acronym for Arc Fault Circuit Interrupter. This device acts as a safety device by “watching” the amperage signature passing thru it and evaluating it to known arc signatures. Because most electrical fires are caused by the heat due to arcing, these devices can be a critical part of home safety. As of 2012, the National Electric Code requires that all circuits in living areas of a home or residence be protected by AFCI.
