Ron,
312.5(C)(g) doesn't say anything about the conduit being installed as a system. The entire exception expects the conduit to not connect to anything at the top & if thats the case, why bother putting in part g of the exception?
The use of conduit for this type of installation is rarely done for protection, it is for apperance, so I don't think Note 2 to table 1 of chapter 9 applies.
Of course, I've been totally out in left field before.
Anyone else have an opinion on this?
