6 AWG XHHW-2 Stranded Copper Building Wire

6 AWG XHHW-2 Stranded Copper Building Wire

Description:

Copper SIMpull XHHW-2/RW90 conductors are primarily used in conduit, cable trays, or other recognized raceways for services, feeders, and branch circuit wiring, as specified in the National Electrical Code (NEC). These conductors are rated for wet and dry locations, with a maximum operating temperature of 90°C. The voltage rating is 600V or 1000V for all sizes. This cable is designed for easier installation without the need for pulling lubricant. RW90 is suitable for open wiring and use in raceways (except cable troughs and ventilated flexible cableways) in wet or dry locations, as per the Canadian Electrical Code. Conductor sizes 8 AWG and larger are rated for 600V or 1000V single conductor copper with XLPE insulation and SIMpull technology for easier pulling.

Common Uses of 6 AWG Copper XHHW-2 Wire

• 65A branch circuits in commercial and industrial buildings (75°C rating)
• 75A feeder wiring in raceways and conduit where 90°C ampacity is permitted
• Main power feeders in commercial, industrial, and residential service panels
• Motor leads for large equipment requiring 600V-rated copper conductors
• HVAC system wiring for high-power air conditioning units
• Backup generator connections for emergency power supply
• Cable tray wiring where NEC allows XHHW-2 conductors
• 60A circuits for 48A Level 2 EV chargers
• 60A feeders to garage, workshop, and pool equipment subpanels
• 50A and 60A circuits for hot tubs, spas, and electric furnace heat strips
• Underground conduit runs to detached garages and outbuildings

6 AWG XHHW-2 Copper Data Center Applications

In data centers, 6 AWG copper XHHW-2 is pulled in conduit and flexible metal conduit for rack branch circuits. NEC 210.19 sizes these circuits at 125% of the continuous load, and the 90°C rating gives headroom when many circuits share one raceway.

• 60A, 208V three-phase circuits to high-density racks with IEC 60309 or CS8365 receptacles, about 17.3 kW at 80% loading

• 60A, 415V three-phase rack circuits, about 34.5 kW at 80% loading

• Feeds to in-row cooling units

• Whips from remote power panels, in flexible metal conduit under raised floors (NEC 645.5(E))
