Multiple Choice

Ideally, the lead height should be equal to what?

Lead height is the vertical point where the external drop cable begins its path from the structure. Setting this height equal to the structure’s height gives the most direct, clean drop from the top of the building, minimizing sag and tension and reducing the chance of the cable snagging on roof edges or architectural features. It also helps ensure adequate clearance from ground-level obstacles and simplifies attachment hardware. If the lead were lower, the drop would require more horizontal routing and could increase bending, tension, and snag risk; if higher, it would introduce unnecessary tension and extra support needs. So aligning the lead height with the structure height provides the simplest, most reliable path for the lead-in.
