Well... I can definitely see the dilemma.
Seems that even if the NEC revised 680 to allow a lesser standard for post-construction installations, owners of buildings under construction could simply wait until a Certificate of Occupancy is issued, then complete the installation, effectively bypassing the more stringent requirements anyway.
I guess it could probably also be argued that 680 only applies to new construction and this installation doesn’t fall into that category. Quite a sticky wicket indeed.
