Dedicated AC line - Contractor wants to use BX instead of romex


I’m having a dedicated in wall AC cable run, about 40-50 ft. I was planning on using VH audio cryo’d 10-2 Romex but the contractor wants to use BX since it’s an urban area and more impervious to mice, etc.

Any thoughts on this?

Also I was planning on wiring the end of the run with an 20 Amp IEC connector so I could plug it directly into my Niagara 7000. I don’t know if they will wire it this way but I thought I could always do that myself later.

Your contractor is nuts. You want the cryo wire. You do not want it in conduit. You are willing to come string it through the holes in the middle of the night if that is what it takes. Etc, etc.
