Whether you can bury service entrance cable depends entirely on the specific cable type and its manufacturing rating. Standard above-ground service entrance cable (such as SE or SECR cable designed for exterior wall mounting or weatherhead drops) cannot be directly buried underground because its outer jacket lacks the robust moisture-proof and crush-resistant armor required for subterranean environments. However, utility companies and electricians can utilize specialized direct-burial cables (like USE-2 or URD aluminum wire) or run standard conductors inside approved underground protective conduits (such as Schedule 40 or 80 PVC) at correct code depths to safely supply underground electrical service from a street transformer to a home.
