"Point of Connection" To Tap, or Not to Tap" [RE-wrenches]

[Bruce Leininger]

Hi all.  Has anyone run into Article 690.64 being interpreted as
prohibiting taps to the load side of the main service breaker?  One
particular municipality is saying that, even with a fused AC disconnect,
taps are not allowed because of Item B (1) which says "Each source
interconnection shall be made at a dedicated circuit breaker or fusible
disconnecting means." 

The only issue that occurs to me is the protection of the section of
wire between the tap and the fuse in the AC disconnect.  Would it seem
reasonable to size that section of wire equivalent to the service
conductors?

Has anybody else run into this?  How have you handled it?

The municipality in question suggests tapping on the supply side of the
main breaker, but that seems much less safe.  The current on the wire
between the fused AC disconnect and the tap then only be limited by the
overcurrent protection on the utility transformer, no?

Thanks for you help.

Bruce
