    The black stripes seem to twist. Kinda cool really.

    Last week I needed to replace a 200 amp three phase loadcenter type panelboard. The existing one was MB but there was also a service disconnect breaker outside. I knew the breaker was out there, but I completely spaced when it came time to order one and I ordered a MB instead of MLO panel to replace it I blame the originally installer who for some reason un-necessarily installed a MB panel which put MB in the front of my mental rolodex.

    Edit to add: The outside MB was bad, it wouldn't shut off. It would have been $700-$800 to replace. I found a new surplus one on ebay, saved the client $350, so I guess all in all we are about even

    Main breaker in panel not even required. You have a main service OCPD in the fused disco. It is protecting the panel already.

    Think about it.
    Where's the rule that states if the service disconnect is not attached to the structure you have to have a disconnect at the building also?

    I cant find it.

    I think this is what you are looking for. The problem here is that outside the building is ambiguous.

    230.70(A) Location. The service disconnecting means shall be installed
    in accordance with 230.70(A)(1), (A)(2), and (A)(3).
    (1) Readily Accessible Location. The service disconnecting
    means shall be installed at a readily accessible location either
    outside of a building or structure or inside nearest the point of
    entrance of the service conductors.

    There is no rule that requires the service disconnect to be attached to the structure.

    Sorry I think this is more accurate

    225.32 Location. The disconnecting means shall be installed
    either inside or outside of the building or structure served or
    where the conductors pass through the building or structure.
    The disconnecting means shall be at a readily accessible location
    nearest the point of entrance of the conductors. For the
    purposes of this section, the requirements in 230.6 shall be
    utilized.

    So if the meter and fused disconnect were on a rack out in the lot nowhere near the structure another disconnect would not be required at the structure itself?
