Running EMT from panel to wall penetration

[theSherpa]

Hey, first post...learned a lot here.

New garage, SIP wall (OSB surface) with panel mounted on it 33" above concrete floor, want to run EMT from panel down to floor, 90 bend, 3' run along floor to a wall penetration I'll create to the outside, transition to an A/C disconnect to liquidtite to a mini-split condensor. Outside emergence of the conduit is 1.5' above grade (just above the foundation wall).

Biggest question is, does code limit how close to the floor the horizontal run and penetration can be, because if it does I can't find it. I will run it as far above the floor as I'm forced to, but want it within a few inches of the floor if not prevented from doing that.

Also looking for guidance around what the penetration should be...thinking an LB, EMT through the wall (5") into the back of an A/C disconnect that has a 20A GFCI service receptacle. I intend the #12 THHN conductors to be unbroken from panel to disconnect.

I pulled a permit and it will get inspected.

Thanks!

No limitation on the height of the EMT. It is considered to provide protection from physical damage. If there is "extreme" physical damage potential, ie; people will end up using it as a ladder, or heavy equipment being banged into it like floor jacks or similar, then you might want to consider using rigid. Poking out the wall into an LB or into the back of the disconnect, either is the proper way to do it.
