§ 39.62. Scope.
The provisions of § § 39.61—39.70 (relating to methods of protective grounding) are specifically directed to all lightning arrester grounding and to the grounding of all circuits, equipment, or wire runways when the grounding is intended to be a permanent and effective protective measure. Such provisions do not require that grounding be done, but cover the methods for protective grounding. The rules requiring groundings are included under parts one, three, and four of the National Electrical Safety Code. Such provisions do not apply to the grounding of arresters on signal circuits, to the grounded return of trolley or third rail systems, nor to the grounding of lightning protection wires if these are not connected to electrical circuits or equipment.
