I know 250.64(B) does not allow the use of FMC for protection. But - what about running the GEC in FMC when the purpose is not for protection.
Scenario: Routing of the PV circuit conductors is through an attic after transitioning from EMT on the roof, then snaking through a stud bay to the service equipment; the GEC runs with the circuit conductors because it is also playing the dual role of the EGC.
Under this scenario the GEC does not need protection - the location and routing of the GEC is plenty safe enough [BTW - the GEC is a #6 stranded].
My understanding of 250.64(B) is that the various raceways listed in that section are selected for the purpose of 'protecting' the GEC; Soares stresses this point [i.e. the purpose of these selected raceways is for protection].
So I ask the forum - when the function of a raceway is not to protect the GEC, are we still limited to using only those listed in 250.64(B)?
