This is 6 AWG stranded copper building wire with XHHW-2/RW90 insulation, made by Southwire with SIMpull technology. It is rated for 600V or 1000V, handles up to 90°C, and works in wet or dry locations inside conduit, cable trays and other NEC-recognized raceways. The SIMpull jacket is designed to pull without lubricant, which saves time on long conduit runs. It suits electricians wiring services, feeders and branch circuits, and it competes with plain XHHW and THHN wire mainly on easier installation and dual wet/dry rating.

Buyers rate this wire highly, with 4.8 out of 5 from 49 ratings. Owners mainly praise the easy pulling and the quality of the copper and insulation.
This is 6 AWG stranded copper building wire with XHHW-2/RW90 insulation. It is used in conduit, cable trays, and other recognized raceways for services, feeders, and branch circuit wiring, as specified in the National Electrical Code (NEC). RW90 is suitable for open wiring and for use in raceways in wet or dry locations under the Canadian Electrical Code, except cable troughs and ventilated flexible cableways.
The conductor is Class B compressed stranded bare copper. The insulation is cross-linked polyethylene (XLPE) with SIMpull technology, which makes the wire easier to pull without pulling lubricant. The insulation is silicone-free, abrasion-resistant, high-heat, and moisture-resistant.
Typical uses include 65A branch circuits and 75A feeders, motor leads, HVAC wiring, backup generator connections, and 60A circuits for 48A Level 2 EV chargers. It is also used for subpanel feeders, hot tubs, spas, electric furnace heat strips, and underground conduit runs to outbuildings. In data centers, it is pulled in conduit and flexible metal conduit for rack branch circuits and feeds to in-row cooling units.
