[RE-wrenches] Tapping Parallel Conductors

[Garrison]

Hi Wrenches,

When making a supply side connection on parallel sets of conductors is it required to tap all conductors on each phase?

I have a set of plans with an 800A interconnection on a 1200A service.  Service has three parallel sets of 500MCM. Plans call for tapping just two conductors on each set of three. Plans are stamped by an EE.  I had been working under the assumption that if tapping parallel sets all conductors must be tapped.

Any issues with not tapping all sets?

Thanks,
