Yet, What is code for buried electrical wires? Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
Does underground wire need to be in conduit? Underground Wiring Requirements – How Deep Do I Bury the Wire? Use direct-burial underground feeder cable at 24-inches deep (or more). You don’t need to use conduit at this depth with UF cable, however, you do need to provide PVC conduit on your vertical feeds starting at 18-inches.
Can you use a chainsaw to dig a trench?
