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. In the case that I referred to it wasn't direct burial or sheathed cable it was individual conductors only, at least from what I could clarify with the manager. Stick a piece of conduit down into the ground and you can't tell. If CG "electricians" do the work, you have no idea what they've done. Many older CGs have conduit from pedestals to panels.
We were at one CG that had #10 romex strung overhead between trees to the sites and the receptacles (with no breakers) were dangling in the air a few feet above the ground. Oddly, it was run by a local gov't jurisdiction too. Wish I had taken a photo.
