2/0 AWG THHN THWN-2 Stranded Copper Building Wire

Allowable Ampacity:

• 145 Amps for General Applications (60°C)

• 175 Amps in Wet Locations (75°C)

• 195 Amps in Dry Locations (90°C) (for derating purposes only).

Description

2/0 AWG THHN/THWN-2 stranded copper wire is rated for THHN (thermoplastic high heat-resistant nylon, dry) and THWN-2 (wet) applications. The “W” indicates water resistance, making it suitable for damp or wet environments when installed in conduit. It supports up to 600 volts and operates at temperatures up to 90°C. The flame-retardant PVC jacket resists sunlight, moisture, and chemicals, ensuring durability even in harsh conditions. Commonly used for high-capacity circuits, subpanels, and industrial wiring, this wire is available in lengths of 25 ft, 50 ft, 100 ft, 250 ft, and 500 ft, as well as by the foot for custom lengths.

What are the Applications of 2/0 AWG THHN Wire?

• Serves as a service entrance wire in medium to large residential buildings, delivering up to 175 amps from the utility connection to the main panel.

• Provides power through main feeder wires to large subpanels and distribution panels.

• Powers heavy-duty machinery and equipment in industrial and commercial environments.

• Supports large commercial and industrial systems, including motors, generators, and other high-current applications.

• Suitable for underground installations when run in conduit, protecting it from moisture and external damage.

• Ensures efficient power distribution across large facilities, campuses, and industrial plants.

Application:

• Type THHN or THWN-2* conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code2.
• When used as Type THHN, conductor is suitable for use in dry locations at temperatures not to exceed 90°C.
• When used as Type THWN-2*, conductor is suitable for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C when exposed to oil or coolant. 
• When used as Type MTW, conductor is suitable for use in wet locations or when exposed to oil or coolant at temperatures not to exceed 60°C or dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 75°C conductor temperature per NFPA 79).
• Conductor temperatures not to exceed 105°C in dry locations when rated AWM and used as appliance wiring material. Voltage for all applications is 600 volts.
