Part of the "6 foot rule" is also the requirement for an additional grounding conductor to be run in the whip if it exeeds that length.

I notice that 410.67(C) talks about "tap conductors", and 410.67(B) talks about "branch-circuit conductors." How does a tap conductor differ from a branch-circuit conductor?

It appears that there is no limit on the length of "branch-circuit conductors" going to the light, only of "tap conductors." My take is that if an MC whip is characterised as "branch-circuit conductors," you can make it as long as you like.

A "tap" is a very limited provision in the code that allows for the use of wire that would otherwise be considered too small for the circuit over-current device.
In lighting, an example of a "tap rule" being applied is with the use of factory made (and Listed) fixture whip...code allows these whips to be as small as #18, even though the circuit may be as large as 50 amps.

Good response Reno. I've seen an awful lot of "daisy chained" installations using whips with #18 wire. Surprising how many guys don't read or understand those kind of code references.
