250.64(D)/2002 permits tap conductors.
For what reason would the "TAP" not be allowed in the service disconnect enclosure?
Scenario:
400A service composed of 2-200A MB panels, each fed by #4/0AL SEU from meter base.
GEC #1/0AL, TAP conductors #2AL sized per 250.66 Note#1.
Why can't the #1/0AL GEC be run and terminated to the ground/neutral bar of one panel and the #2AL TAP conductor terminated on the same ground/neutral bar and be routed to and terminated at the other panel?
OR
Same scenario, except both panels have a PVC nipple between them.
Why can't GEC be routed into one panel and connected to the TAP conductors with a split bolt (as would be done on the outside of the panel) connector. The TAP conductors would then be routed and terminated at the ground/neutral bar of each respective panel. One would travel through the nipple to the other panel.
I usually make the TAP to the GEC on the outside of the panel and route the TAP conductors to each enclosure as specified in the Code Section.
This becomes a problem when the panels are flush with the finnished surface as the TAP must be accessable.
Just contemplating other options.
