Applications
Low friction type 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 2001.

When used as Type THHN, conductor is suitable for use in dry locations at temperatures not to exceed 90°C.  When used as Type THWN-2 or TWN75 conductor is suitable for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C whenmore
