NUISANCE ARC FAULT CIRCUIT INTERRUPTER (AFCI) CIRCUIT BREAKER TRIPPING DIAGNOSTIC TOOLAn arc-like radio frequency (RF) noise detector device is configured to detect and display RF noise on a residential circuit branch that cause or contribute to an arc fault circuit interrupter (AFCI) circuit ...
fire. In the US these circuit breakers have been required since around 1999 by the National Electrical Code for residential homes. While the intention of these more robust circuit breakers is good, there have been many issues with nuisance tripping and they have become a real issue for ...
and they seem to expand requirements for every new Code cycle. There are receptacle based and circuit breaker based solutions. Each have their own unique advantages/disadvantages and applications.
do not have the contact bounce, but rather present the entire cold filament load to the breaker, from zero to full-load-amps in less than two half cycles. Solid state dimmers routinely contribute to nuisance tripping when supplied by an AFCI, combined with the control of loads greater than...
FSW is determined as the current being less than a threshold (12% of the current peak) in sample counts. In arcing waveforms, the FSW becomes elongated and random. However, this can happen in many non-arcing waveforms as well. To reduce nuisance tripping the present method introduces two ad...
