Only people who know what they are doing should work on large 3-phase panels.

Don't envy the spark who has got to sort that lot out!

Only people who know what they are doing should work on large 3-phase panels.

Is there any suggestion that the last person to work on it didn't know what he was doing?

No, purely a speculation and a warning to anyone thinking of attempting such work.

Could easily have been a faulty component inside the panel, who knows.
