Good day ,

I have a armored power cable entering a metallic enclosure through a RGS conduit . The armor of power cable shall be grounded at both ends of load . is it acceptable to terminate some steel wires to ground bus bar inside enclosure to comply with NEC 320.108 ?
 
If the RGS is continuous from enclosure to enclosure you are fine, the AC is simply conductors inside a steel conduit.

320.108 is a construction specification, it is not applicable to your question. What is, is 320.40 and how you are going to accomplish that.

And if the RGS is not continuous, a complete raceway, but, rather, is a sleeve, there are "go-from" fittings that will permit the ending, and bonding, of the AC metal sheath at the entry to the RGS (the end farthest from the enclosure). The stripped out AC conductors continue through the RGS sleeve into the enclosure.

Yes. Rigid galvanized steed. We also call it GRC Galvanized rigid conduit. but the code adopted RMC a few years ago, I think, because it also encompasses brass, aluminum and stainless steel now.
