About this detail

Grounding and bonding configuration for a transformer installation, showing the high voltage enclosure, transformer tank, and low voltage switchgear. The primary side features high voltage bushings connecting phases A, B, and C to the transformer windings. The secondary side shows a wye-connected configuration with phases A, B, C, and neutral point Xo routing through low voltage bushings to the switchgear. A main bonding jumper and supply side bonding jumper are sized per the Canadian Electrical Code, connecting to designated ground pads on the transformer tank. A grounding electrode conductor ties the internal ground bus to an external earth ground.
