why do dogs pee on fire hydrants?
A shunt only allows a junction for electricity to flow around a circuit, so a shunt trip is a circuit that is monitoring another circuit and designed to disconnect input voltage/circuit breakeretc What is the trip value and do you have an interface relay to disconnect the primary circuit?
Here's a harder one. Why doesn't God save the North Koreans when they just want to die because they're being persecuted? And he doesn't want people to commit suicide. There are MANY reasons why God lets things happen, one of which being he doesn't micromanage, whoever you are. Plus there's that bible verse that says it rains on the righteous and unrighteous. Good and bad fall on both. Why ask, did it happen to you?
