I think the wiring is very bad and that's it's obvious they didn't know what they were doing. But?
What happens if you overload one of those #12 conductors? Not much. First the insulation would melt and smoke and then with more heat the conductor would burn into.
Where is the fuel to start a fire? I have removed main breakers where the lugs were glowing red hot and still no fire because there was no fuel in the area.
12 THHN is rated 30 amps because of insulation limitations, bare conductor in free air can probably carry 100 amps especially a short length like pictured here. It obviously was never loaded too much for too long though or else insulation would have been compromised.
