You can post many very long message as far as I'm concerned - good information.
I like the "turning the wire into a heating element" statement.
Reminds me of working on a building at a kids camp in the middle of Mexico. I found a 50 amp breaker feeding a water heater on the other end of a long building with a 14 gauge wire draped across the ceiling joists in the attic. With no electrical supplies within a half day's drive I couldn't do a thing. It was several years before I could get back with supplies. The building was still there - yea!
