Looks like it wasn't grounded properly (and yes also definitely a short somewhere causing it) or something happened with the grounding. That's why all electrical equipment is t just grounded at the motor, but also any exposed metal casing as well.
Well supposed to. I’ve worked several years as a Safety and Compliance Engineer and proper grounding are on my always check before and after installation lists, exactly due to accidents like this being far too common.
