I should also make two more comments. First, the diameter of this PCB is 1.45", to match the diameter of the multi-section capacitor I am replacing. The QC connectors I am using for the twist lock connectors are positioned exactly where they will pass through the cutouts in the chassis. And second, all clearances and creepage distances are in excess ofthe 3mm design constraint. Hence why there are no cutouts or notches in the PCB. I believe the smallest distance measured was 5 mm.
