Direct-buried conductors, cables, or raceways, which are subject to movement by settlement or frost, shall be arranged to prevent damage to the ______ or to equipment connected to the raceways.

The correct answer is that direct-buried conductors, cables, or raceways must be arranged to prevent damage to the enclosed conductors. This arrangement is essential to ensure the integrity and safety of the electrical system, as settlement or frost movement in the ground can exert forces that might compromise the physical protection of the conductors.

Enclosed conductors have specific insulation and protective materials designed to maintain performance under normal operating conditions. If these conductors are damaged due to environmental factors such as frost or soil movement, it can lead to electrical failures, which may cause interruptions in service or create hazardous situations.

Utilizing appropriate installation techniques, such as providing sufficient slack and using conduits or protective barriers, helps to accommodate ground movement while preserving the structural integrity of the enclosed conductors. This mitigates potential issues and ensures that the electrical system remains safe and operational.
