UL Ratings for Sundial's Cloth-Covered Wire
UL-Recognized vs. UL-Listed
People often ask us why our wire is UL-recognized rather than UL-listed. The term UL-listed
is used for assembled products, such as a lamp or fan. UL-listed assemblies must be composed
of UL-recognized components. Since wire is a component, not an assembly, it is UL-recognized rather than
UL-listed.
UL-Recognized Wires
Some of our single-conductor and twisted pair wires are UL-Recognized under
UL standard 758, Appliance Wiring Material, under the following UL styles:
|
gauges

The reason that some of our twisted pair and single-conductor wires are UL-recognized and some are not is due to the fact that there is no lacquer
on our wires. Previously, UL was recognizing wire made to the UL standard 758, styles 1016 and 1009, when it was not lacquered. Recently they have said
that they will no longer do that. If the wire is not lacquered, it will not be considered UL under those specifications. However, we still have wire in stock
that was UL approved under UL 758, even though it too is not lacquered. Please note that the construction of our wires has not changed, just UL's willingness
to recognize it. We plan to take steps in the future to get our non-lacquered wires approved under different standards.
Wires recognized under UL standard 758 are approved for internal wiring but not
as power cords which would be under UL standard 62, Flexible Cords and Cables. However, since the
wires are UL-recognized, the UL inspector for your assembly can, at his/her discretion, accept them as UL-recognized
components.
Non-UL-Recognized Wires
The following styles of Sundial Wire are not UL-recognized:
- some twisted pair wires
- some single-conductor wires
- pulley cord
- overbraid
- parallel cord
- 12-gauge knob and tube wire
The wires internal to all of these wires except the 12-gauge and the parallel cord are constructed the same
way as the style 1016 wires that we use in our twisted wires, but UL does
not have an approval for wires that are twisted and then braided, only for when they are braided and then twisted.
Again, a UL inspector does
have the ability to approve these wires for your assembly even though they are not UL wires.
