Grounding Metallic Conduits with Communications Cables

[al]

For Ethernet communications cables (Cat5 or 6) installed in rigid steel conduit is the conduit required to be grounded?

what do you mean by "grounded"?

I think you may mean bonded. Many might argue that 250.104(B) applies here. IMO it is a good practice to bond all metallic systems.

And a counterpoint in that argument may well be 250.86 Exception No. 2.

I think it might be a good practice but I am not convinced it is actually required.

It would depend on whether the exposed metal is considered likely to become energized.

I have never liked that phrase. There should never be any non-current-carrying metal parts "likely" to become energized. Making those parts very unlikely to become energized is a major premise of the NEC. I see it as a contradiction of terms.
