1/0 THHN wire, a commonly used building wire, falls in the “one aught” gauge category within the American Wire Gauge (AWG) system, making it ideal for high-current applications. 1 0 ga thhn wire features durable thermoplastic insulation and a protective nylon sheath, offering excellent heat resistance and protection against environmental factors. Rated for 600 volts, number 1 0 thhn wire is a staple in both residential and commercial electrical circuits, including in outlets and switches. Available in various colors for easy circuit identification, 1 0 awg thhn wire suited for use in conduits and cable trays in a range of environments, though not for direct burial. Adherence to UL and NEC standards ensures its safety and quality.

FAQ

What is 1/0 THHN wire typically used for?

1/0 THHN wire is commonly used for branch circuits, feeders, and service conductors in commercial and industrial electrical systems where higher current capacity is required.

What does “1/0” mean in 1/0 THHN wire?

“1/0” (one-aught) indicates the conductor size, which is larger than AWG 1 and designed for higher ampacity applications.

Can 1/0 THHN wire be used in wet locations?

Yes, when the conductor is dual-rated THHN/THWN-2, it is permitted for use in wet locations, as commonly supplied in the market.
