Participants at one of my recent workshops had questions pertaining to reversefed transformers (backfed) The input side was 480 volts (V), threephase, and the output side was 1/8V They wanted to know if the output side of 1/8V transformer could be used as an input side, and if so, how was the electrician to bond and ground the transformer?Various primary and secondary voltage combinations This external transformer has multiple input taps to allow you to supply it with 1/8V or 1/240V power, with the output set at 1/240V This transformer provides the isolation and provides 1/240V out to the bypass switch, so neither of the two issues described above are relevant
