Application and description

Xhw-2, RW-90 building wires are typically laid in conduits or other National Electrical Code (NEC) certified piping for service, feeder and branch circuit wiring. Xhw-2 is permitted for use in wet/dry environments with temperatures up to 90°C and in industrial environments where superior insulation toughness and chemical resistance are required. It is used in 600 volt circuits. 1/0 AWG and above can be used on cable mounts certified by the National Electrical Code and comply with IEEE 1202/UL FT4 flame test and ICEA T-29-520 (210,000 Btu/hr) flame test.
