@Norton posted:I don’t see any way the PSX AC can be any faster than a 180 watt brick. This is for AC not DC. AC passes through zero 120 times a second. You can’t sense a short circuit when there is no current. Only as it approaches max voltage can it sense a change in current.
On a DC layout it can respond faster than 8 ms but not AC.
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?
