It's not debatable. There are thousands of miles of metal conduit in service as the sole EGC and it is performing fine. I bet you rarely see Multi Wire Branch Circuits as well.It's debatable. I'm considering to just put a note for contractor to verify ground continuity... Kinda feel iffy about using metal raceway as an ECG because , rarely see anybody do it, and I rarely see it.....
