MC to emt transition

[Davebones]

MC striped back about 10 ft and sleeved thru emt . There is a mc connector to rigid coupling to emt connector . Is this allowed ?

Transition could have been accomplished without the rigid coupling but is still compliant

 

[Davebones]

What would be the correct type of fitting to use ?

MC to EMT fittings are available

With the availibilty of the EMT/MC fittings IMO some will argue that the conn/coupling/conn method is not code compliant.

Myself, I would wonder if the conductors are still part of the MC cable at that point (I doubt it), and then, if they are labeled every 24" to comply with 310.120(B)(1), or if they need to be to be used as single conductors.

Some would argue that the conductors within the raceway require surface marking due to the section you've posted. There are some manufacturers who use marked conductors within MC cable.

In my opinion 310.120(B)(1) is a construction requirement not an installation requirement.

If it is applied as a installation requirement we could not strip more than 24" of NM to enter a panel.

You might be right, but how would an inspector know if the sparky stripped out 10' of conductor from NM cable to install in LFMC to an AC unit?

Maybe he or she would assume that nobody buys bare #10 for an EGC.

If it's a 2 conductor NM cable you have the issue of a white conductor in the sealtite, so if a inspector opened up the disco, would have to be blind not to notice.

You could use two black conductors and forget the white.

We keep some reels of that around for just such an occasion. Got it special order back in the 90's or early 2000's I can't remember for sure.

Wouldn't a fitting similar to this be acceptable ?

Blind inspectors are very prevalent around here.

Yes they would be fine.
