(d) Where a
						trailing electric power cable passes over an industrial railway track or
						vehicular road, it shall be securely supported by poles, horses, or other means
						so as to provide a safe clearance between the cable and any equipment used on
						the railway or vehicular road.
(e)
						Trailing electric power cables shall be connected to mobile equipment in such

						trailing electric power cables have been cut or damaged so that their
						insulation protection is substantially reduced, or when the conductors of such
						cables have been sliced, the jackets shall be repaired and vulcanized so that
						the repaired section will have insulating properties equivalent to the original
						electric cable cover.
