I have a product listed to "CAN/CSA" and what is unclear is if this is an acceptible listing in the US? There is 3 CSA listings I am aware of,CSA, CSA-US, CAN/CSA. Of these 3 it is my understanding that CSA-US and CSA are accepted in the U.S. but everyone I work with is unsure about the "CAN/CSA" listing.
NRTLs (can/csa) listings?

Unfortunately that web site is US-oriented and so does not tell us anything directly about marks that apply to Canada only. I guess you could infer that any CSA marks other the ones shown are either out of date or else apply to Canada only.

When the mark is "CSA" alone, the product has only been certified to Canadian standards. Other CSA marks may indicate additional compliance with US standards. A "UL" mark alone indicates only American National Safety Standards, typically ANSI or ASTM, were used to test for compliance. See 29 CFR 1910.7(c), especially 29 CFR 1910.7(c)(4).
To answer the OP; a "CAN/CSA" mark is not a FedOSHA recognized NRTL mark. The US and Canadian test protocols are very similar, but not identical - thus the need for clearly distinguishing marks. Oddly enough, some "local" US jurisdictions (through ignorance) may accept CSA carte blanche.
As of this post the "Current List of Test Standards Recognized Under the NRTL Program" is being updated and is temporarily unavailable. A link to it may eventually be found here. The UL list isn't 100%, but it's pretty comprehensive.The entire FedOSHA NRTL program is pretty well outlined there too. The link to 29 CFR 1910.7 and its Appendix A above is the actual statutory language.

The building code for the jurisdiction should have a chapter listing all of the NRTL's, commonly chapter 35. Another chapter is a paragraph that says NFPA70 is the electric code. That building code chapter 35 follows through to the electric code just like chapter 1 Administration does.

Which brings us back to the absurdity of different states or even local jurisdictions having different lists of Nationally Recognized Testing Laboratories.

I thought the OP was trying to confirm US reconized NTRL -- As you can see from the site that there are several markings associated with CSA for US applications. some products will have more than 1 marking -- in which only 1 of several needs to comply for US standards. How many different NTRL lists have you seen?

Different, none personally, but whenever a list is written directly into a local regulation rather than pointing to an external reference it runs the risk of getting out of sync with the current recognition status.
