What about supports? This is about 6' or so of LFNC. What would you write up, if anything?

Installer needs to read 356.30 again.
Or maybe for the first time?

I'm like 0 for 20 asking ECs if they have a copy of the code book on the jobsite or in their trucks. Was on a massive jobsite with about 10 buildings with 56 condo units in each and no one had a code book.

Isn't it like 12" and every 3' for support....I know it changes at like less than 3' but I would have to look it up to be sure...

356.30(4) Securing or supporting LFNC-B is not be required when less than 6' long only in a accessible ceiling.

I'm no expert! But I would say at the least it should be secured within 12" of the box. So the vibration is transferred to the wall more than the plastic connector at the box. but 356.20 (2) would only allow it to be 3' if you are claiming no support is needed to allow flexibility.
