Aplications
Type XHHW-2 / RW90 copper conductor 600 V is primarily used in conduit or other recognized raceways for services, feeders, and branch circuit wiring, as specified in the National Electrical Code. Type XHHW-2 conductors may be used in wet or dry locations at temperatures not to exceed 90°C. Voltage rating for XHHW-2 conductors is 600 volts.
Construction
Type XHHW-2 / RW90 copper conductor 600 V is annealed (soft) copper. Insulation is an abrasion, moisture, and heat resistant cross-linked polyethylene (XLP). Conductor sizes 2 AWG and larger listed and marked sunlight resistant in black only.
Specifications
Type XHHW-2 conductors meet or exceed all applicable ASTM Specifications, UL Standard 44, Federal Specification A-A-59544, NEMA WC 70 (ICEA S-95-658) and requirements of the National Electrical Code® (NFPA 70).
