Claim:
A kit for retroactively installing a grounding ring that electrically couples a motor shaft to electrical ground comprising: an annular ring of conductive material having a central bore and at least one hole through the annular ring that is outboard of the central bore to enable a threaded fastener to be inserted through the hole in the annular ring and engage an opening in an endplate of an electrical motor, the central bore having at least one electrical conductor extending from the annular ring of conductive material into the central bore to enable the electrical conductor to be coupled electrically to a shaft extending through the endplate; at least one threaded member having a head and a threaded shaft, the threaded shaft being inserted through the hole in the annular ring and received within the opening in the endplate to secure the annular ring of conductive material to the endplate; and a bearing cap that is configured to engage the endplate and secure the bearing cap over the annular ring, the bearing cap having a central bore to enable the shaft to pass through the bearing cap.
