Got a call from customer that" sparking happened" when they energized the ancient but still happily chugging along Electro Controls quad dimmer rack after a long COVID break. Photo shows a rodent's meal inside the rear of the rack. This was a wire from the neutral buss to the control card cage 3-phase power connector.
Bare copper area had made contact with nearby phase buss bar. Always an adventure.
