UL Listed 600V 14AWG 12AWG 10AWG Thw Tw Thwn Thhn Copper Electric Wire

APPLICATION
THHN or THWN-2 conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code. The voltage for all applications is 600 volts.
When used as Type THHN, the conductor is suitable for use in dry locations at temperatures not to exceed 90°C.
When used as type THWN, the conductor is suitable for use at temperatures not to exceed 90°C, dry locations or 75°C in wet locations or not to exceed 75°C when exposed to oil or coolant.
When used as type THWN-2, the conductor is suitable for use in wet and dry locations at temperatures not to exceed 90°C or not to exceed 75°C when exposed to oil or coolant.
Conductor temperatures not to exceed 105°C in dry locations when rated AWM and used as an appliance wiring material. The voltage rating for all applications is 600 volts.

CONSTRUCTION
THHN or THWN-2 or MTW copper conductors are soft annealed copper. #14 – 4/0 AWG uses a
combination unlay strand and 250 kcmil and larger uses a compressed copper strand. The wire is insulated with a tough heat and moisture resistant poly vinyl chloride (PVC), over which a nylon (polyamide) or UL Recognized equal jacket is applied. Available in black, white, red, blue, purple, green, yellow, orange, brown and gray. Some
colors are subject to economic order quantity. Marked sunlight resistant in sizes 2 AWG and larger.
THWN-2 is available in sizes 8 AWG and larger.
