But in his case as he explained, he plugged it in, started screwing in the butt plate and smoke started appearing, so it had to be arcing at the connector (look at his pics)
Even I find it odd..
Path of least resistance....... there isn't much metal touching between the pins and sockets compared to the higher current handling wires, so that'd be the weak point for the current to focus on.
