NESC and NETA {2013} are both ANSI standards and are both pretty much aimed at
the utility-distribution crowd: aka, 4 kV and above. Colorado Brian Gregory

What a web of “interconnecting” (and not!) US regulations,
standards, codes and regulatory authorities!. But we still sometimes then get
US-based questions on the “European Wiring Regs” or similar - seems
like a case of “Physician, heal thyself” first. J

And not to confuse the issue even more, but then there is the N.E.S.C. -
National Electrical Safety Code (or nowadays ANSI Standard C2) published by
IEEE. Adopted in most states in some fashion, except for California which does
its own thing. I think this one is primarily aimed at utilities though. Dates
back to 1913.

Correct, National Electric Code is pro forma NFPA70, or at least per
administrative laws of each U.S. state.
But the reader should understand that there are state and municipal regulations
that also specifically and formally refer to NFPA79 and NFPA99 as national
building codes.
And the NFPA itself refers to 99 as a national 'Code'.
The scope of the thread was OSHA per the NEC and associated test standards,
where my premise is that 'code' and standards evolve and are contrived via
various circular references.
And Mr. Nute pointed to the problem of the various NEC versions enacted locally
(most, but not all, have adopted 2014) vs the referenced product safety
standard that would be used to verify compliance by the AHJ. And the OSHA
cannot affect any force for an organizing change as their statue scopes only
workplace safety.

NEC is specifically NFPA 70, otherwise known as the National Electrical Code.

By 'NEC", will assume that the reference is something like NFPA70 or 79. There
are, as we all know, many other elements of NFPA construction requirements .
NFPAs can reference ANSI, IEC, NEMA, ASME, IEEE, and other standards; and many
ANSI, NEMA, and IEEE standards reference one or more NFPA elements in the scope
statements. So the references are intended to be circular.

“Each NRTL has a scope of test standards that they are recognized
for…”
https://www.osha.gov/dts/otpca/nrtl/
Nationally Recognized Testing Laboratories (NRTLs)
www.osha.gov
OSHA's Nationally Recognized Testing Laboratory (NRTL) Program. Recognizes
private sector organizations to perform certification for certain products to
ensure that ...
NRTL certification for OSHA purposes is limited to its scope of test standards.
Check out your favorite NRTL for its OSHA test standards.
We don’t yet know whether the NEC is limited to the OSHA NRTL scope test
standards or is open to all test standards the NRTL certifies products to.
(Awful English, but understandable.)
And, we don’t yet know whether the locally-adopted NEC will be the OSHA
NRTL scope test standards or will be open to all test standards the NRTL
certifies products to.
