Without a lift pole, what is the maximum service drop span for #2 triplex cable?

• A. 60 feet
• B. 100 feet
• C. 85 feet
• D. 120 feet

Answer: (B)

Span is limited by how much the conductor will sag between supports while still meeting required clearances in worst‑case temperatures and wind. For a #2 triplex service drop, if you’re not using a lift pole to tension and position the line during installation, the practical maximum between poles is about one hundred feet. Going farther would let the line sag enough to risk contact with the ground or objects and to fall below minimum clearance, so longer spans would require a lift pole or intermediate supports. In contrast, shorter spans would still work but aren’t necessary in this scenario; the key point is that without extra equipment, about a hundred feet is the limit for this conductor.
