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.

Get the Synergistic Research Romex it’s only $50,000 for 50ft

I was only joking about the 50k . For starters the best thing if your swapping your panel out is get the panel with the silver plated buss then run a dedicated 20A thats 10/2 or 2 , when I ran my dedicated outlet since I was running 1 I just ran 2 so i have 1 20a for my surge and another for my Subs I have dual subs  so im using both outlets for the subs , overkill I know but , before I did all this I got major sag on the line lights were dimming bad so I knew I needed a dedicated outlet . and the first outlet that has the surge protector on it the second outlet I have a IFI AC purifier in it so all 4 outlets  are being used

@johnspain:  Thank you for the link.  It explains the differences in language that is easy for a novice to understand.

Before you get into an argument with your contractor you might want to look up the code in your area for what is required to pass inspection. Example in Chicago area almost all electrical wire must be contained in conduit. If there is no code restriction tell him or her what you want and if they won’t go elsewhere.
