This is probably an oldie question on here...
I'd like to break the AC "hot" if there's too much AC current. This would be due to a short or ground fault. Or.... Shunting the load to burn a fuse on the AC line would be ok too..
I'm afraid that a fuse maybe too slow to protect the electronics from burn out.. Let's say the electronics I'm protecting cannot withstand 1.5x overcurrent.
What's faster than a fuse on a AC line?
Details Load: The load on the line is not a transformer and is not inductive. Current draw: 2Amps Line voltage: 240Vrms, 60Hz Surge rate: guessing 45Amps in 1uS
Rule: 1/4watt current sense resistor.
The load circuit has a power bridge rectifier. Maybe I could modify the bridge with transistors to interrupt the surge current? D from BC
