    I would say that rules for wiring methods don't apply to the inside of enclosures, in general.

    The cable is a wiring method that gets from one enclosure to another. It could be a type of conduit instead. Either way, the rules for that wiring method stop when you get to the enclosures. When you bring the cable into the box and you remove the sheath and separate the conductors to land on various terminals, you are no longer using a cable as a wiring method. There are plenty of rules that apply to the enclosure, which take over. Just as if I bring conduit to a box, there are fill and derating rules that apply in the conduit and then as soon as the conductors enter the box those rules end and there are different rules for fill, etc.

    The NEC specifically spells out the interior of a raceway in a wet location is considered a wet location. I do not believe there is any such reference to the interior of an enclosure in a wet location so an inspector would be hard pressed to give you a Code reference.

    Welcome !
    In the OP's situation, I would anticipate a small stub of raceway sleeveing the cable as it exits the building envelope and enters the disconnect enclosure. Would that small stub of raceway also qualify a "wet location", because it technically is a raceway in a wet location?

    As I recall, that's exactly the situation with coming into the back of an outdoor service panel on the side of the house with all the home runs. We talked about this before and I think some kind of wire enclosure under the panel was being used so that you would bring your wiring out, up and into the bottom of the panel instead of into the back and this thing would go over your wiring creating a dry location.

    I just recommended making outdoor service panels illegal.

    I can tell you this- NC has had exterior panels for as long as I have been here and longer (1978) and there has never been an issue with the nm cable being inside the panels.
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    I never expected there would be but some inspectors don't like that 1/4" or less between where it exits the siding and goes into the connector on the back of the panel. They say it's a wet location because water can get behind there.

    And some sort of enclosure to come out and into bottom of panel can get just as wet or even more wet than 1/4" or less into the back of a panel I would think. This is just an area for nit-pickers to dwell on when they can't find anything else to nit-pick.
    I live for today, I'm just a day behind.
