Chris -

On the basis of workplace safety, listing by a nonNRTL is
largely useless.  On the other hand, if the persons
providing the listing are a competent engineering firm,
using licensed engineers, there may be some credibility to
the listing (for instance, the NEC allows waivers of certain
requirements, if the installation is under the supervision
of a licensed engineer), though it still falls short of the
cited bureaucratic dictum.  Keep in mind, that butting heads
with OSHA will probably only give you a headache.

I note that the OSHA response you provided left out 29 CFR
§1910.399 (iii), for custom equipment.  In this case, an
NRTL might not be required.  You make no claims that the
equipment is custom built and the conspicuous absence of a
reference to 29 CFR §1910.399 (iii) in the Director's letter
leads me to believe it is not custom built equipment.

Hair splitting: OSHA does not create law; only Congress can
do so.  OSHA's charter from Congress, however, states that
it's regulations have the power of law, so there's not much
practical difference.
