Earlier in the year I did a bunch of wiring in my workshop and ran a power feed to a disconnect on the outside of the back wall of my shop for a mini-split air conditioner.

Since then, I've decided I'd like shelving on the inside at that location and would like to install my blower unit on an adjoining wall, near the corner. This means that, as things currently look, the outside unit and the inside unit will be on different walls.

Is there anything wrong with running the copper lines around an outside corner to accommodate this? Both the inside and the outside units would be within a few feet of the corner.

 

No issues. You can use slim duct to cover it
