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.

Look at page 16. Read pages 31 thru 36.

I would argue many should read all of this ... about 15 times!  Maybe something will sink it. Worst case, they may give more though to their purchases.


One thing from this presentation is why lots of separate runs are a bad idea as they likely also have separate runs for the ground. That is a good way to induce more voltage difference between grounds. Do a heavy gauge run to a small sub-panel and plug everything in there.





Considering that pretty much every state has as law the National Electrical Code, what place where laws don’t matter do you live?  Cities often take these things more seriously because fires don't just take out one house, they can take out a whole bunch.
