110v transformer feeding db



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?

  • Sorry yeah it’s 55v 0v 55v and only a breaker on one 55v leg. Also what are the ZS values for 110V circuits I can’t find it in the regs?
