Are the conductors in AC and/or MC marked? I've seen many mentions of folks wanting to strip the jacket off Romex and run the wires through conduit, which idea is nixed because the conductors aren't marked. Is the situation different with AC and MC? Otherwise, I don't see how one could use this fitting to transition from AC/MC to EMT.
EMT to 3/8" flex makes sense, though, to continue a THHN run into a motor whip, etc.
