    NEC requires a white (or grey) grounded conductor sized per T250.102 to be brought into the Service for fault path.

    Yes but I don't believe we're discussing a service.

    If the conductors originate from a transformer secondary I believe it applies regardless

    There is the possibility the "what you believe" may not be what the Code states

    Can you provide a Code reference that requires such an install ?
    At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.

    I agree, the OP is asking about an SDS.

    and services don't required supply side bonding jumpers which basically is doing the job of the grounded conductor being brought to a service where there is no load. So you have similar animals under a different name.

    I don't see anything in this thread that would indicate that a service is involved, the OP even mentions SDS. An SDS and a service are two different things although some believe that they are treated the same.

    I still believe a dedicated white grounded conductor is required to be run with circuit conductors from all transformer LV secondaries to panels, disconnects etc even if no phase to neutral loads exist.

    and I, for one, will gladly enforce that on inspections if you only give me a valid Code reference.
    "Dale says so" will not work on my rejection notices

    Fine - if you can explain how a CB will trip or fuse will blow without a fault path from the device back to the transformer I will gladly rescind my last post
