I have 2-5"pvc (1 spare conduit) counduit routed underground to a pull box. One conduit has 3#500kcmil single conductor cables and 1#1/0 ground. As I read article 314.71(B)(1) I am required to size this box based on the outside diameter of the largest cable or conductor times 36 plus additional entries through the same wall. I have attached a sketch for reference. Any comments would be apprfeciated. I also based the depth of the box on the spacing requirements for locknuts of 2-5" conduits.
