Required buried depth of cables over an open run?

Explanation:
Outdoor wiring needs to be buried to protect it from damage, wear, and other hazards. The standard minimum depth for direct burial cables in an open run is 24 inches below finished grade. This two-foot depth balances protection from digging, lawn equipment, and frost movement while keeping installation practical for residential jobs. Deeper depths, like 36 or 48 inches, aren’t usually required for typical open-run installations unless local codes or specific conditions demand it. If the conductors are placed in conduit or armored cable, or if a jurisdiction has different rules, the depth can change, but 24 inches is the common baseline.
