The requirement for maintaining a 3-foot vertical clearance from the edge of the roof shall not apply to the final feeder conductor span where conductors are attached to _____.

• A. the side of a building
• B. a utility pole
• C. rooftop fascia
• D. an anchor block

Answer: (A)

This rule protects people from contact with live conductors that span over the roof edge by keeping a 3-foot vertical clearance. An exception exists when the final feeder span ends by attaching to the side of the building—the conductors then run along the wall rather than over the roof edge, so the exposure that the clearance addresses isn’t present. In that configuration, the 3-foot vertical clearance from the roof edge does not apply. Attachments that involve placing conductors on a pole, rooftop fascia, or anchor block still involve edge exposure, so the clearance would apply in those cases.
