Apart from Phil can none of you realise the significance of my asking what size of the transformer feeding the rectifier was? Hint PFC!
Because DC doesn’t go through a neutral transition 100 times per second it is harder to break. To sustain an arc requires energy. You are not going to get that energy in a control panel due to the impedance of the control transformer feeding the rectifier! The energy let through is going to be minuscule!
