How do I protect a wire in the wall?

I'm slowly wiring my house as I have time. One of the things I'm doing is after adding a sub panel I'm wiring a generator inlet to the sub panel with the interlock.  The issue I'm having at the moment is how to go about protecting the 8/3 wire that comes through the wall. The wire is the outside variety with the grey outer shielding. The way I had to drill the hole to get it down to the basement means the wire will be touching the drywall or get really close to it for about 6-8 inches before it goes into the hole to head down to the basement. I'm not sure how to go about protecting it so it isn't inadvertently pierced as the house gets put back together.

    This is what conduit piping is supposed to do--is the outdoor shielding metal or plastic? Is the hole where it penetrates your wall sealed?

    It is shielded wire?   That means it has a steel shell over the wire? You are not going to puncture that except with a direct hit using a 4 inch spike.  That is what shielded wires mean in my country. It is in a flexible metal conduit.  So you are good.

    The WALL is all the protection the wiring should need.

    Needing to ask SCREAMS "I am not REMOTELY qualified to wire for a generator.

    Don't do ANYTHING without supervision by a competent electrician.

    I'm going to assume the sub-panel, is a generator transfer panel/switch or some such option.   The cable should be rated for running it in interior walls. Either lay out where it is running so you don't risk piercing it, of you can run a metal plate in front of it. So you'll know you hit something and stop.

    Service entries should be sleeved - the minimum size of the sleeving depends on the diameter of the cable. The cable you are talking about should be armoured anyway.

    Thread it through a piece of conduit or PVC pipe?

    If nothing else, cut a hole in the drywall.  You can always patch the drywall.
