Proper Grounding

[mjnunn]

It it a code violation or just bad practice to use non-metalic liquid tight flex and flex fittings with metalic conduit and condilet fittings?

A properly sized grounding conductor is in the raceway.

Not sure what you mean by flex connectors are they non-metallic or are they actually steel flex connectors

Are you saying going from lets say EMT with a connector and a threaded coupling to a piece of carflex with a carflex connector?

Any metallic fittings would have to be bonded. 250.4(A)(3)

What I have is a run of Rigid Metal Conduit that changes to plastic flex (non-metallic) plastic flex connectors attatch the flex to the RMC. again, there is a grounding conductor in the conduit run.

They do it on highway overpasses all the time to allow for expansion...

As long as there is an EGC in the conduit and the section of RMC beyond the non-metallic flex is bonded to it, you are in compliance.
