@turkey_hollow_rr posted:Folks are reporting no spark when shorting the circuit to test the PSX regardless of what the amp setting is. I like and depend on the PH 180 breaker too, but it can't shut of current that fast. How do explain that?
Simple, the PSX1-AC uses solid state switching to interrupt the current, the PH180, at least the older version, uses a relay to interrupt the current. So, think microseconds or less for the PSX and milliseconds for the PH180.
