Does SER have markings on the individual conductors? I have an install where I want to strip the last 3' of the cable jacket to enter EMT going into a garage panel.
 
I believe it does. I'm thinking of XHHW.
I would approve your install.
You being a moderator on this site has nothing to do with my answer. 😀

Is that 3 feet of conduit exposed in the garage? Just thinking that if that last 3 feet of the SE is exposed in the garage and you are using the conduit to protect it from damage, can't you just run it unstipped though that conduit and cite Protection from Physical Damage?
 
I don't think it is guaranteed to have markings. However all that I have done recently does have markings. I like it because I like to transition to underground without an expensive Polaris and/or future trouble spot. So will switch to individual conductors (and insulated ground) without a splice where it transitions to UG, if it has markings.

SE or SER is not allowed in conduit going underground, markings or not.

Yes it's for protection from where it enters from the basement. Can SE cable be run into EMT without some sort of fitting mechanically connecting it to the EMT?

If the EMT is terminating in an enclosure, it is my opinion that the SE must be secured to the other end of the EMT.

That is what I thought too. The one end of the EMT is going into a panel the other end is stubbing into the basement ceiling. Since I cannot find a listed changeover fitting I was going to use a piece of metal wireway or a box to make the transition.

338.12 Uses Not Permitted. 338.12(A) Service-Entrance Cable.
Service-entrance cable (SE) shall not be used under the following conditions or in the following locations:
(1) Where subject to physical damage unless protected in accordance with 230.50(B)
(2) Underground with or without a raceway

Yes, once you strip off the outer jacket from SER, if the inners are marked XHHW, then all you have is XHHW conductors. In which case you can transition to underground conduit at an above ground box or proper changeover fitting with no need to splice the actual conductors.

Cheers, Wayne
 
Yes, that is my interpretation also.

What is SER cable? It is a bunch of wires surrounded by some tape and a plastic jacket over that. If you remove the jacketing materials, it is no longer SER, all you are left with is a bunch of wires that either need to be terminated, or used according to their own markings.

Do you need a "changeover fitting"? If you take a two screw connector into a threaded coupling and then an EMT connector, do any of the instructions of those fittings prohibit that?

If you used PVC, you could use a female adapter.

My question still remains, which fitting has a prohibition? Does a 2 screw connector say " only for use with boxes and cabinets"? This is from UL 514B:

4.12 FITTING – A means for securing conduit, cable, or electrical metallic tubing to an enclosure, box,
or raceway system.
 
I would use a connector, coupling, and clamp without hesitation.

I believe a reasonable inspector would applaud the effort.
 
I wouldn't transition without a box. The bare ground will turn to powder in the wetness underground over the years so it needs to transition to insulated ground. Otherwise, I have done it. Also with large MC, ground is usually already insulated there too.

Aluminum yes, copper no.
