Hi Jim:
You've had a number of answers with good data.
NRTL certification is required for two totally
unrelated applications.
1) NRTL is required for workplace safety.
2) NRTL or equivalent is required as a part
of the local (city, county, state) building
code safety.
Certification by a NRTL is required under the
USA workplace safety law, aka OSHA. If you sell
your product to an employer (who is responsible
for workplace safety), the electrical equipment
used by his employees must bear the mark of an
NRTL. (NRTL is the means for electrical equipment
safety administration under OSHA.)
Certification by a NRTL or equivalent is required
by the USA National Electrical Code. This code
(or a version of it) is adopted by local (state or
county or city) jurisdictions responsible for
building codes. Most codes require certification
of electrical equipment. Most codes require
certification by an NRTL, but some codes have a
specific list of acceptable certification houses.
As far as I know, all NRTLs are accepted by all
building codes; some codes may specify the cert
house, and some codes may include cert houses
that are not NRTL.
For an example of a local jurisdiction that
specifies cert houses, see:
http://ladbs.org/LADBSWeb/LADBS_Forms/TestLab/ETL_list_lab.pdf
(The City of Los Angeles has its own electrical
testing laboratory and safety certification label.)
As a general rule for the USA all electrical
products must be certified by an NRTL.
(Some retailers, such as Wal-Mart, also require
safety certification of the products they sell,
and often have their own list of acceptable cert
houses. NRTL works for them, too.)
Here is the current list of NRTLs:
