Except for the prohibition against double-locknut and locknut-bushing means of bonding, there are no other restrictions for LFMC beyond those of Article 350 in Division 2. For your particular interest see Section 350.60; read and understand the cross-references as well.
thank you.
but I read your reply in the below link, and your reply #18

?
but, how can use(install) LFMC in unlimited length without a problem with ground-fault current path ???
LFMC cannot be used in an unlimited length either with or without a bonding jumper in a hazardous location. In unclassified locations study Article 350.
so, do you mean that it is permitted to use LFMC with unlimited length in C1D2!!
plz I need your help with clear reply.

I'm not going to do your homework for you. I'm not going to do your design without a significant consulting fee.
This is a simple as I can make it if you aren't willing to do the homework:
This is a simple as I can make it if you aren't willing to do the homework:
- You cannot use a double-locknut or locknut-bushing alone to bond anything including LFMC and Section 501.30(B) Exception.
- No matter how you bond it, the LFMC will be in the ground-fault path to some degree.
- IF you intend to use LFMC as the "sole" EGC in a Division 2 location, it still must be installed per Article 350 and Section 250.102 with their appropriate cross-references AND:
- it must be less than 6' with an external bonding jumper OR
- it must have an internal bonding jumper and length is unspecified; however Article 350 and Section 250.102 with their appropriate cross-references still apply.
