Siemens Intelli-Arc diagnostic tool for residential AFCI circuits
By Anthony Capkun
Siemens Energy & Automation has expanded its residential line of combination type arc fault circuit interrupters (CAFCIs) to include an Intelli-Arc diagnostic tool. The company claims the new tool makes it easier to troubleshoot AFCI circuits by improving troubleshooting accuracy and reducing the number of visits to the problem site. The diagnostic tool can be used with any circuit breaker, regardless of brand. The device also provides information such as the type and magnitude of the fault, and indicates how close an event is to causing an AFCI to trip.
