Re: Automatic Transfer Switch Failure
It's hard saying not knowing, of course, but a loose connection getting hot is one reasonable and not unlikely explanation for what you saw.
Although colloquially "shorting out" is sometimes used to mean almost any electrical difficulty, a loose connection heating up has nothing to do with an actual short circuit. A short in the transfer switch would cause the pedestal breaker to more or less immediately trip from the very high current that flows.
