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.

I would not want/use regular AC armor cable, (commonly called BX cable), to feed audio equipment. If AC must be used spec AC HCF only. Example of regular and HCF AC cable: https://www.afcweb.com/cross-reference/comparison-ac-mc-cables/ Look at the diagrams of each shown at the bottom of each. Example of construction of regular AC cable: https://www.afcweb.com/ac-hcf-armored-cables/ac-lite-armored-cable/ Example of AC HCF cable: https://www.afcweb.com/ac-hcf-armored-cables/hcf-90-health-care-facilities-armored-cable/ IF MC (Metal Clad) cable is allowed it is recommended over AC cable for branch circuit wiring to feed audio/video equipment. MC is even recommended over MN (Romex) cable. AC and MC are not the same. . |
As a result the most likely best path forward is to use the hi purity copper in conduit.It’s just 10-2 with ground NM (Romex) cable that has been sent out and cryoed. (Not by the manufacturer). I wonder what the electrical inspector would say about that? OP said: I was planning on using VH audio cryo’d 10-2 Romex |
