Where it is necessary to carry high potential wires near buildings, they must be of such a height or distance from the building as not to interfere with firemen in event of fire; if within twenty five feet (25') of building, they must be at a height not less than that of the projecting cornice or other projections; if closer than twenty five feet (25') the line must be raised two feet (2') above the cornice or projection for every five feet (5') closer than the twenty five foot (25') limit. (Prior code § 8-4-15)
