Grounding liquid tight

[A.tomas]

I been researching grounding on non metallic liquid tight and metallic liquid tight and I came across a few conflicting areas of interest. One saying (all liquid tight) needs a separate ground over 6ft. And another saying only metallic liquid tight this applies to if the conduit of over 6’. Some saying this only applies to if the wiring has no ground wire in the run , and others saying even if there is ground wire in the conduit if it’s over 6’ it need a separate ground bond?

What if I’m running UF 10/2 w/ ground. Does it still matter.

And my run is only 8 foot long. Just want to make the inspector happy and not be called out.

I don't know where you're getting this information but it's all over the place. LFNC always requires an EGC. For LFMC of lengths 6' or less look at 250.118(6).

Yes I know, but my perhaps misunderstanding is why does the LFNC need a (separate ground) if the UF-b cable Iam running through the LFNC has a ground already. Like I stated above I’m running 10/2 with ground, the LFNC is fitted and fastened to a metal disconnect that is grounded. Why the extra EGC if it is already attached to ground?

Does this apply to rigid PVC also.
