UL vs. NON UL listed cable

Horse for Horses...
What am I getting with a UL listed cable, fitting.

Noticed Carol cable - both wires, same grades. UL stamped was 2X.
Same thing on Liquidtight Conduit. Same make, same model. Non UL was about 1/2.

Here's my take on it from being an electrician and working with the stuff.

IN MY OPINION:
The off-shore stuff is rarely UL listed and is lower in quality......especially the fittings.
I only use UL cable so I'm not exactly sure what the non UL stuff is like but I can imagine.

To clarify, for example

SOOW Carol Cord. Jacket markings are the same - including the MADE in USA on both. The only difference was price and NON UL marking.

Same thing for flex.
Can't recall what brand but they were the *same brand- make- model*. Just the non UL stamp.

So for comparison purposes, these were the same exact items, made by the same manuf (just short of different model #'s , no UL , and quite a price differential)

If the inspector looks and sees the stuff used without the UL they will probably make you remove it. Not worth the chance to risk doing it again and losing money.

The non-U.L. Listed Liquidtite is generally a lot more flexible and I also don't believe it has a copper bonding strip. Either product will probably work, but inspectors usually look for the U.L. markings.

There is a possibility that the non UL rated cable is for use where unapproved components are acceptable.
Trailers and other low voltage applications come to mind.

I'm not sure what Minor Design/Material changes are there....

Nor do I know how UL is achieved in the Electrical world of things.
But assuming the manuf . has Paid and got the UL listing for such said part.
Why make another variant that is the *same* purpose wise - but put it at a pricepoint that is 1/2 of it. While COO plays a role, both SO cords were USA marked as well !

Difference between UL and non-UL could be minor flaws found in the QC process. Don't know for sure -- just throwing it out there.

Yep, could be minor flaws or a minor change in the specifications it was built to. Anything less than what U.L. has approved and it can't bear the U.L. markings.
