Color:
Black

Applications:
Type XHHW-2/RW90 building wire is intended for general purpose applications utilized in conduit, underground in conduit, or other recognized raceways for services, feeders, and branch-circuit wiring as specified in the National Electrical Code (NEC). Type XHHW-2/RW90 is permitted for 600 volt applications and can be used in wet or dry locations at temperatures not to exceed 90_C. Suitable for applications requiring low-leaking circuits and a dielectric constant of 3.5 or less.

Features:
Available in sizes 14 AWG through 1000 KCMIL. On 250 KCMIL and larger, sequential foot markings located every foot for easy measuring. For 1 AWG through 4/0 AWG, sequential foot markings on master reels only unless otherwise specified. 6 AWG and larger rated Sunlight Resistant in all colors. 1/0 AWG and larger are rated for cable tray use and comply with IEEE 1202/FT4 (70,000 Btu/hr) flame test and ICEA T-29-520 (210,000 Btu/hr) flame test.
