Bushing Required for a single Cat 6 Cable sleeved through FMC?

And how often do you think you would see a problem if you didn't put an anti-short (redhead) bushing on the ends of AC and MC? How about if you didn't use bushings in the holes of steel studs when using Romex? Probably very infrequently but the NEC requires them. The NEC doesn't specify them for data because it's LV so there is no safety issue like there is for power. But just because it's LV doesn't mean the same reasoning shouldn't be used. What's good for the goose is good for the gander and even though it's not required it's just good workmanship.

I agree, we often far exceed the minimum requirements of the NEC but the OP is asking if it's required because he has an inspector who says (incorrectly, unless a local code) that it is required when it is not required.

Saw one job early on where the v/d/v cable was pulled thru steel studs w/o bushings. There was only one tool to fix that mess: side cutters to cut it all out and rerun it. The jackets, and, in innumerable places, the pair insulation, were sliced to pieces. I doubt NM would fare much better.

I agree tho that good workmanship is prudent with LE/LV.
