Underground direct burial cable has been around for at least 50 years , that I know of
Local code decides if it can be used, or must be in conduit
It is quite common, even in high voltage applications
I remember putting in direct burial cable for a 6200v line on airport runway edge lights over 40 years ago
Agree 100% Direct burial feeder cable is all I have ever seen used in both new park construction and service upgrades in existing parks. It is also what the power companies that service my parks use to bring in the services. Those applications are exactly what direct burial cable is designed for. The usage of direct burial by no means an indication of substandard construction.
