How far should the backfill be compacted from direct buried cables during installation?

During the installation of direct buried cables, it is essential to compact the backfill to prevent damage to the cables and ensure optimal performance. The recommended distance for compacting backfill around direct buried cables is typically 6 inches. Compaction at this distance helps maintain the stability of the ground surrounding the cables while allowing enough soil coverage to protect them from physical damage and environmental factors.

This practice is critical in preventing voids in the soil that could lead to settling, which might stress or damage the cables over time. Proper compaction also helps in providing resistance against the weight of the soil above and any potential external loads, enhancing the longevity and reliability of the buried electrical system.
