Some things do and some things don't.

What type of equipment are you speaking of?

only if the code says it does.

some things are specifically required to be listed. if not specifically required to be listed, unlisted stuff can be used.

there are a few places that require control panels be listed. that is beyond what the code requires.

UL is not the only agency that can list stuff.

Equipment needs to be approved, not necessarily listed. Only the AHJ can approve equipment.

Usually, this approval is based on a UL listing or other listing. If a product is listed, it doesn't necessarily mean that it is approved. Most of the time it does. Very seldom is a listed product not approved.
 
The earlier posts pretty well summed it up.
There are a few specific areas ( 680.24, 680.23, 411.3 are a few examples) where listing is required.
Local jurisdictions can required listing as part of their approval process (The State of TN does).
For the most OSHA requires listing of equipment and accepts a number of listing agencies along with UL. Here is a link to OSHA approved listing agencies

All of the Chapter 3 raceway articles and some of the cable articles, require the use of listed products.
 
If the NEC or other code required a specific NRTL, Nationally Recognized Testing Laboratory, like UL, the lawsuits would be filed like crazy. I would think it would have to be listed by a NRTL, which UL is the biggest but not the only player.

It does not state UL and I don't think it even uses the term nationally recognized testing agency. It uses the term listed. The closest it comes to using "nationally recognized testing agency" is in the definition of listed, but that definition only says "an organization that is acceptable to the authority
having jurisdiction"

Thanks Don. It appears as though being UL listed is just being assumed. "An organization that is 'acceptable' to the authority having jurisdiction" is the key statement.

Yes those are the key words. Most AHJs use the OSHA list of NRTLs. I think that there are 17 on the current list.

"UL" is often used as a generic term much like "Crescent" wrench or "Kleenex". All three are trademarked names that have come into common generic use.
 
If it helps you I posted a link to the OSHA approved NRTLs in Post #5
 
UL does play a unique role among rest of the NRTL list.
UL establishes the formal US standards against which all of the other NRTLs do the testing.
UL can also test to Canadian standards, just as CSA can test to US standards.

And it's going to be accepted by the greenest electrical inspector.
