Specification

300 MCM XHHW-2 Copper Building Wire: 

Allowable Ampacity in 300 MCM XHHW-2 Copper Building Wire in Duct: 240

Also Known As:

300 XHHW-2 Copper Building Wire, 300 XHHW Cable, 300 XHHW Service Wire, 300 XHHW Copper Wire.

Applications:

XHHW is a multi-purpose electrical wire with cross-linked high heat water-resistant insulation. The most common applications include raceways for branch circuit wiring, conduits, services, and feeders. It is also used as a building wire. XHHW is suitable for industrial applications due to its toughness and excellent resistance to chemicals. The electrical wire  is suitable for temperatures up to 90°C, with a voltage rating of 600 volts.

Construction:

Conductor:

The cable has an annealed bare copper conductor (solid or concentrically stranded). The conductor has excellent electrical conductivity and excellent resistance to moisture. The conductor also has excellent resistance to compression, pressure, and heat.

Insulation:

The cable is insulated with a cross-linked polyethylene jacket (XLPE) that serves as a protective armor to the conductors. It is flame-retardant and resistant to abrasion, corrosion, moisture, dryness, chemicals, and heat.
