The United States' National Electrical Code (NEC) recently expanded Arc-Fault Circuit Interrupter (AFCI) requirements (see "Arc-Detecting Circuit Breakers Will See Wider Use" at www.electronicdesign.com, ED Online 15682). This decision led to some passionate mail from Electronic Design readers who...
The National Electrical Code® (NEC®) has required Arc-Fault Circuit Interrupters in residential and limited commercial applications for many years, and they seem to expand requirements for every new Code cycle. There are receptacle based and circuit breaker based solutions. Each have ...
jurisdictions have adopted the NEC’s AFCI requirements so it is important to check local code requirements. What Causes AFCI Arc Fault Breakers To Trip? Arc fault circuit breakers can trip for a variety of reasons but the two most prominent reasons are improper wiring of circuits or ...
