What two methods are described for routing service drop cable under obstacles such as driveways or sidewalks?

• A. Manual routing or boring machine
• B. Above ground on a support cable
• C. Direct burial without protection
• D. Floating conduit over the surface

Answer: (A)

When routing a service drop under obstacles, the two approaches described are manual routing and using a boring machine. Manual routing involves creating a trench by hand and pulling the cable through a protected conduit beneath the obstacle, then backfilling to restore the surface. A boring machine achieves the same goal without surface disturbance by drilling a horizontal bore under the driveway or sidewalk and pulling the cable through, typically in conduit for protection. These methods are favored because they place the service drop underground while minimizing surface disruption and providing proper protection and code compliance. Alternatives such as above-ground support, direct burial without protection, or floating conduit on the surface don’t meet the requirement to get the cable under the obstacle or to protect it adequately.
