there is a DB board fed from a centre tapped transformer only on single pole breakers. The board feeds instrumentation. Is there any issue changing it to 110v and tie the neutral to earth there is no socket outlets fed on this so can’t see it as an issue?
If you have not got a loop tester use your approved voltage tester just to see what the voltages are between the transformer outlet socket terminals are, you should not be able to kill yourself on the output side of the tool transformer, but take it steady on the 240 volt side. ?
