One EGC, yes, just as with any circuit, whether there is a neutral or not.120/208V panel. RTU heat feeds show 3 phase(hots) and no neutral. Shouldn't a separate ground(EGC) be required? If not why? Thanks.
You can use the metal raceway as an EGC. If there is a flexible raceway involved and the equipment will move or vibrate then you must install a wire type EGC within the flexible raceway. I'm glad that you clarified the word "ground" by calling it the correct term, EGC.
Thanks. What code section is that regarding the EGC in the FMC? Thanks.
Yes it usually does but we always figure the conduit to be the EGC.It’s likely listed in the project specs that all conduits have an appropriately sized EGC.
Usually the only place I see the ground size specified in a schedule is on panel feeders.

On our current project we're doing the same thing, no wire type EGC's. Seems that the building owner wants code minimum to save money on the 2.3 billion dollar project.

So this note would refer to the EGC?
So the EGC and the grounding conductor is the same?I think that a wire type EGC is implied but technically a metal raceway that complies with 250.118 would also be a "grounding conductor".
Using the terminology that you've posted from the spec yes. It's confusing when the person writing the spec uses poor, incorrect, or slang terminology.So the EGC and the grounding conductor is the same?
