NEC 314.23

[Isaiah]

We have a small pull box (8”x8”x4”) installed at elevation 10’ above the floor. There are 4, 3/4” RGS conduits entering the box all of which are supported within 3 feet of the box….except for one — it is supported about 5’-6” from the box - does this conduit also need to be supported within 3’?

I don't know of an exception to the 3' rule when entering a box with RMC. It funny because there is an exception for EMT that allows an unbroken length to be supported at 5' from the box.
