Besides, what type of Romex can be buried?
UF cable is THHN conductors plus a ground encased completely in PVC. Romex is a brand name for non-metallic paper bonded cable (NM-B, as printed on the jacket) with a PVC jacket. This is why type UF is suitable for burying and wet locations (or dry) where NM-B cable is suitable only for very specific dry locations.
Secondly, does direct burial cable need conduit? However, if you only need a power supply (without wires to control lights from inside the house,) you can use a direct burial cable, placed in the soil without conduit. The NEC (National Electrical Code) requires that UF cable be placed in a trench at least 24 inches deep.

The most common types of direct burial cable used in residential projects are underground service entrance (USE) and underground feeder (UF). Type USE cable is usually black and is most often used for buried lines that bring power from the utility's transformer to individual houses.
How deep do you have to bury Romex?
Bury in the Ground: Dig 24 inches. At 24 inches you can bury underground feeder cable, using PVC conduit to 18 in. below ground only where the wire comes up. If you're considering running a power line underground through your yard, you have four options.
