Wiring may very by assembler. Just where the junctions occur may depend on what the assembler decides. So if the schematic shows wiring one way verses the way the assembler wires it, well you may have a beef of how it was routed along with many owners. So the schematics are "Proprietary Intellectual Property". There are manufactures that provide all drawings, but they are Class B, class C, and class A manufactures. Unfortunately this does not allow just what sockets are connected to which breaker. It would be nice that the units were assembled via a wiring list as NASA and MIL hardware is wired. All units are wired the same. Easy to trace a problem and no three junctions in a insulation displacement socket.
