Unconditional Satisfaction GuaranteeNo Shipping Fees Above 302 Months to Decide. Returns Simplified.The definitive standard for 200-amp residential services and high-capacity industrial feedersengineered with dual-rated THHN/THWN-2 insulation and a friction-reducing nylon jacket for maximum reliability in 600V applications.
The 2/0 copper building wire is a high-performance conductor engineered for maximum power delivery. It is the primary choice for 175-amp to 200-amp residential services, large commercial rooftop HVAC units, and industrial switchgear. Our stranded construction is essential at this gauge, providing the necessary flexibility to navigate 2-inch or 2.5-inch conduit bends and land securely in high-torque mechanical lugs.
Dual Rated (THHN/THWN-2): Engineered for dry locations up to 90C (THHN) and wet locations (THWN-2), providing maximum versatility for indoor and outdoor conduits.
Tough PVC/Nylon Jacket: The high-heat and moisture-resistant PVC insulation is protected by a tough, friction-reducing Nylon outer sheath, making for easier pulls through tight bends.
High-Conductivity Copper: Manufactured with soft-annealed stranded copper to provide maximum flexibility and superior electrical conductivity for branch circuits and feeders.
Oil & Gasoline Resistant: The specialized jacket is designed to resist chemical degradation, making it ideal for industrial environments and service station wiring.
200-Amp Residential Services: The standard conductor for 200A main service entrances in single-family homes (per NEC 310.12).
175-Amp Commercial Feeders: Used for high-output commercial distribution to heavy machinery or sub-panels.
Large Standby Generators: Connecting industrial-grade standby generators (30kW+) to automatic transfer switches.
Industrial Battery Storage: Primary feeders for utility-scale battery backups and UPS systems.
Large Commercial EV Hubs: Providing the backbone power for multiple high-speed DC fast chargers.
