Specification

4/0 THHN THWN-2 Stranded Copper Building Wire

THHN THWN-2 Copper Building Wire Allowable Ampacity in Duct: 260

Application:

THHN stands for thermoplastic high heat-resistant nylon. Known for versatility and durability, it is the most common type of building cable. The double marking THHN /THWN-2 indicates that the electrical wire is suitable for wet and dry conditions equally (The letter "W" means that it is water-safe). Additionally, the cable is resistant to corrosion, excessive dryness, and the impact of chemicals. The building wire is rated 90 degrees Celsius in both wet and dry locations. The electrical wire
is rated at 600 V.

    FAQ's

    What are the particular applications of 4/0 AWG THHN?
    • As large service entrance wires in large property
    • As main feeder wires to major subpanels and distribution panels
    • In large-scale HVAC systems
    • In heavy-duty industrial machinery
    • In underground installations in conduit if double-ranked as THWN
    • For power distribution in large factories and multi-building residential complexes.
    What does THHN stand for?

    THHN stands for "Thermoplastic High Heat-resistant Nylon-coated."

    What is THHN Wire suitable for?

    THHN wire is suitable for electrical conduits, indoor and outdoor use (as long as ranked THWN), building wire across industries, and control circuits.

    Can THHN Be Direct Buried?

    THHN does not have an appropriate rating for direct burial because of its construction, but THHN/THWN-2 with a double rating can.

    Does THHN Have to Be in Conduit?

    Yes, THHN has to be installed in conduit at all times as per NEC. The only exception to this rule is when THHN is installed in control panels. 

    Is THHN Rated for Wet Locations?

    THHN is rated for dry locations, while THWN is rated for wet locations.

    Can THHN Be Used in Underground Conduit?

    The wire used for the underground conduit should have a THWN-2 rating for wet locations.

    Can You Run THHN in Walls?

    You can run THHN wire in walls within conduit or raceway, but NM-B wire is generally a more popular option for indoor wiring.

    Can you use THHN wire for automotive?

    Using THHN wire for automotive applications is not recommended.

    Is THHN wire waterproof?

    THHN/THWN is not waterproof. While it is suited for wet or damp environments, it cannot be directly submerged into water.
