(A) General. All direct-burial conductors, including the equipment grounding conductor if of aluminum, shall be insulated and identified for the use.
There are several examples with- in the NEC where the equipment grounding conductor is required to be Insulated.
Here is one I found to be peculiar , I say that because it doesn’t fit the explanation I give when I am asked why the equipment ground has to be insulated. Or why can’t I use UF cable, NM cable or SER cable.
I know what my explanation is for why the insulation of the equipment ground conductor what’s yours ?
