For buried limited energy cable, which reference point is often used to locate access points for testing, repair, or rerouting?

• A. In a spec sheet
• B. Using a GPS system
• C. On a blueprint
• D. Using thermal imaging

Answer: (B)

Using a GPS system provides a practical, consistent reference for locating access points on buried limited-energy cable. In the field, the actual cable is underground, so you need a surface position that you can see and share with the crew. GPS gives real-world coordinates that tie directly to maps, as-built records, and GIS data, so you can pinpoint the exact spot of a pull box, handhole, or splice vault for testing, repair, or rerouting. This makes it easy to mark, locate, and return to the point later without relying on outdated drawings.

Blueprints can show where something should be, and spec sheets cover equipment details, but they don’t provide current, on-site coordinates. Thermal imaging reveals heat and activity but doesn’t give reliable location references for access points.
