The current carrying service conductors are insulated for the voltage being supplied (see Rule 20.8-F), and the point of attachment of the service drops is not more than 18 inches back of the front face of the building wall facing the pole line from which the service drops originate.

Service drops are not required to clear buildings any specified horizontal distance but shall be so installed that they clear fire escapes exits, windows, doors and other points at which human contact might be expected a horizontal distance of not less than 3 feet.

Where service drop crosses over metallic or non-metallic nonwalkable overhang or patio cover vertical clearance may be less than 8 feet, but not less than 24 inches providing such service drops consist of abrasion-resistant cables having a grounded metallic sheath and are insulated for the voltage being supplied.
