Even though the stapel does not say it is rated for mc
In my opinion if they are UL listed staples 110.3(B) will prevent you from using them for MC if the labeling only says NM.
However there is no requirement to use listed staples so buy unlisted ones and go nuts.
I have used BX staples for MC for years and have only been shot down for it once ..
The inspector said BX and MC are not the same :grin:
The staple container said BX and did not say MC .. so he was actually correct .. it was not much to go back and use MC straps in place of the staples
Victim of a power-monger.That's pretty ridiculous in my book. You can use a cable tie with a nail but not a BX staple?
