Compression coupling used between GRC and LFMC conduits

[Isaiah]

We have a 3/4 rigid metal conduit connected to 90 degree elbow, connected to a metal compression type coupling which connects to a 2 foot long LFMC and then attaches to electrical cabinet - the installation is indoors (not roof top)
Does the compression-type coupling interrupt the fault path? Or is the EGC within the circuit conductors sufficient?

The EGC is adequate for bonding purposes but the compression connection to the LFMC is screwy.

Im not really clear on what you have here. Is the compression coupling for RMC but it has LFMC jammed into one end? If so I would say that is not kosher.

How is the compression coupling connected to the LFMC? Is there a rigid coupling on the end of the 90° elbow? I've never seen a direct RMC to LFMC fitting.

I think I've seen them but not in a compression type, the RMC side was female pipe thread. I know I've seen FPT to EMT compression couplings
