Are you saying it’s mandatory for every electrical product to be certified
by an NRTL in the workplace?
I was under the impression that only those listed here: OSHA's Nationally
Recognized Testing Laboratory (NRTL) Program - Products Requiring Approval

It's mandatory, but not enforced by OSHA unless an issue arises.
There are a few cities that do enforce it. Los Angeles being one of them.
If their inspectors find such a product they will require it's removal and
that includes trade show demos.
One company I dealt with many years ago was paying for site inspections of
their products when installing their products, instead of certifying their
products.
Once you have a CB Report, getting a NRTL cert isn't too difficult or
expensive.

John and James,
Thank you so much for your valuable feedback.
I see a lot of products that are used in the professional market that do
not have any type of 3rd party certification and they are being sold on the
market and they are from some big manufacturers. So would you agree that
3rd party certification is not mandatory but rather valuntary?
Thanks
Peter

By the way, "NRTL" used to say "UL". Leonard Frier (owner of MET labs),
god bless that man, took OSHA to court and in 1988 the OSHA regulation
changed from "UL" to "NRTL".
Here is a copy of the Federal Register back in 1988.............

Hello and Happy New Year!!
I hope to simplify and clarify the vagueness - See OSHA's definition of
acceptable installation below.
OSHA requires NRTL if there is an applicable Standard (item 1). If there
is not an applicable Standard the AHJ can accept his own evaluation or
another Federal agency's evaluation (item 2), or if the equipment is custom
the AHJ can accept the manufacturers test data (item 3).
Our experience is Field Evaluation labeling satisfies most AHJs for items 2
and 3. I believe AHJs do not want the liability of accepting non-Certified
installations and prefer an NRTL FE label at a minimum.
https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.399
Part Number:1910
Part Number Title:Occupational Safety and Health Standards
Subpart:1910 Subpart S
Subpart Title:Electrical
Standard Number:
1910.399
Title: Definitions applicable to this subpart.
GPO Source: e-CFR
Acceptable. An installation or equipment is acceptable to the Assistant
Secretary of Labor, and approved within the meaning of this subpart S:
(1) If it is accepted, or certified, or listed, or labeled, or otherwise
determined to be safe by a nationally recognized testing laboratory
recognized pursuant to § 1910.7; or
(2) With respect to an installation or equipment of a kind that no
nationally recognized testing laboratory accepts, certifies, lists, labels,
or determines to be safe, if it is inspected or tested by another Federal
agency, or by a State, municipal, or other local authority responsible for
enforcing occupational safety provisions of the National Electrical Code,
and found in compliance with the provisions of the National Electrical Code
as applied in this subpart; or
(3) With respect to custom-made equipment or related installations that are
designed, fabricated for, and intended for use by a particular customer, if
it is determined to be safe for its intended use by its manufacturer on the
basis of test data which the employer keeps and makes available for
inspection to the Assistant Secretary and his authorized representatives.
Best Regards and Be Safe,
John

Happy New Year.
The US Dept of Labor has a mandate to enforce workplace safety regulations.
One of its many agencies is the Occupational Safety and Health
Administration which is tasked with ensuring a safe work environment by
enforcing product compliance by the application of US standards and done by
accredited laboratories. That means products that are within scope of at
least one UL standard must be shown to be compliant to that standard by a
Nationally Recognized Testing Laboratory. (an accredited laboratory and
OSHA runs the NRTL accreditation program)

Subject: [PSES] Mandatory NRTL certification
Happy New Year to all
I was asked by one of the engineers that I work with if getting safety
certification for a product in the US is mandatory or not? i.e do
manufacturer of electrical or electronics have to have certification from
NRTL or other 3rd party labs? The products in question are 100% used in
professional environment and are not intended for general consumer market.
If this is a mandatory requirement, where can I see the requirements written?
Thanks
