Adding to that, with all the proprietary cloak and dagger voodoo behind AFCI protection, I would ask how do we even know that the AFCI circuit breakers own circuitry will work as intended at that 500 ft. distance, since no UL listed remote field verifiable test equipment for these actually exists.
The test button on the AFCI cb or device seems to only test the circuitry at the point of supply. So it appears that the industry is operating entirely on the premise that the manufacturers say they will work… and that is it.
Are they possibly attempting to use the similar situation that exists for GFCI’s and using GFCI “testers” to keep the super secret AFCI design under wraps for good?
