Description / Abstract:
These requirements cover single-conductor and multi-conductor,
unjacketed, 18 – 10 AWG (0.807 – 5.16 mm2), low voltage
LED wire rated 105°C – 250°C (221°F – 482°F), and 300 or 600 volts,
suitable for installation in dry and damp, or wet locations. These
wires are for use with signs, outline lighting, and interior
lighting where the wire is only connected to a secondary circuit,
is only accessible during user servicing of the sign, and is not
required to be additionally enclosed by the sign enclosure, in
accordance with the Standard for Electrical Signs, UL 48.
Assemblies that include these wires and are intended for use as
components of signs shall meet the requirements in the Standard for
Electric-Sign Components, UL 879.
Wires that are surface marked "EX" are for use as exposed runs
between a cable tray and utilization equipment where the wires are
continuously supported and protected against physical damage using
mechanical protection such as struts, angles, or channels.
