About this detail

The primary side shows phases A, B, and C connecting to the delta configuration. The secondary side displays a wye configuration with phases A, B, C, and a neutral terminal Xo connecting to the neutral bus. A neutral bond connects the neutral bus to the ground bus, with sizing determined per the Canadian Electrical Code or one-line diagram. A grounding electrode conductor runs from the ground bus out of the transformer enclosure to connect to a ground bar within the room. Equipment ground and secondary feeders are routed accordingly.
