I inspected a 4th floor 2008 condo unit (22 floor condo building) today and there are no bare EGC’s in the sub-panel. This is something I haven’t seen yet for a newer build and don’t understand why I don’t see any EGC’s / individual branch circuit EGC’s.
Meter and disconnect are on the 5th floor. Neutral buss is appropriately not bonded and the ground buss only has one larger gauge green wire (8 gauge?) attached. The white neutrals are labeled “equipment grounding path component” which is also throwing me off.
Receptacles are testing grounded and I have no reason to think otherwise except I can’t determine where the EGC’s are connected.
Can someone help me understand why I don’t see bare EGC’s? Are they connected to the single green wire outside of this sub-panel?
That sounds right, thanks Christopher! Off my game with an illness the last few weeks…should have been able to come up with that one on my own with a little thought, duh.
You posting “metal conduit” was all I needed to get pointed in the right direction And now I’m getting getting refreshed on all the different types of metal conduit/cabling.

Sure! Years ago, I was also confused and got so sick of reserching to only ever come up with no direct answer, or some BS about how one of them has a ground wire (or thin metal strip), while the other doesn’t, and then something to do with the material the ‘armor’ is manufactured from and whether it could be used for grounding or not!
Finally, I got fed up and said “F*ck it” and just stuck to AC.
I’m not sure how accurate the information is in Jeffery’s link. Type AC has been called BX even after the bonding strip was added in the 1950’s. It still called BX to this day in the field.
Note; There are 4 links in that post, two of which are known to this association as reliable resources. The other two were simply quick Google results. I thought I would expand on my previous answer to your question.
