Installing a DMG DMU103V euro vmc nominal voltage is 400. I have a delta to wye 230-400volt transformer. Ground is bonded to X0 on output side. Ive got 240 here with a hot leg. Im seeing 436 volts on the 400 volt taps and 386 volts on the 360 taps. Internal transformers for accessory voltages can be set to 380, 400, or 440. Is it better to go under voltage or over voltage?
At the previous location the transformer was wired to a 240 service the same as mine, it was wired using the 400 volt taps.
