Exactly as Expected and On Time

Its always sketchy ordering from a website you have no experience in, especially when they are 20% cheaper than competitors. However, I ordered 440ft of 1awg copper wire and could not be happier with the quality and speed. I was also impressed that I was able to get multiple colors of wire for the same cost. (Usually everything other than black is more expensive!) Will buy again!

Product Information

Specification

1 THHN THWN-2 Stranded Copper Building Wire

THHN THWN-2 Copper Building Wire Allowable Ampacity in Duct: 150 Amps

Also Known As:

1  thhn, 1 awg thwn 2, 1 awg thhn, 1 stranded thhn, 1 gauge stranded wire, 1 copper wire, 1 awg stranded copper wire, 1 awg Copper wire, 1 awg building cable, 1 awg conduit wire, 1 awg nylon wire, 1 awg construction cable, 1 awg thermoplastic-insulated copper wire, 1 awg THHN-PVC tray cable.

 1 THHN THWN-2 Applications:

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.

THHN Applications include:

  • Building Wiring: This encompasses everything from lighting circuits to outlets in homes, commercial buildings, and industrial facilities.
  • Conduit and Cable Trays: THHN is designed to be pulled through conduit, making it ideal for structured wiring systems in commercial and industrial settings. It's also commonly used in cable trays in industrial facilities.
  • Control Systems: THHN can be used for wiring control circuits, including those for machinery, HVAC systems, and other building automation components.
  • Machine Tool Wire: In manufacturing and industrial environments, THHN is commonly used to wire machine tools and equipment.
  • Large Appliances: THHN wires can be used for connections inside large appliances like ovens, ranges, and HVAC units.
  • Motor Connections: For connecting motors in both residential and commercial settings
  • Feeders and Branch Circuits: In electrical distribution systems, THHN wires can serve as both feeders (which extend from service panels to subpanels or major appliances) and branch circuits (which extend from panels to outlets, lights, or individual appliances).
  • Service Entrance: While specific SE cables exist for this purpose, THHN wires can also be used for service entrances when appropriately configured and protected.

Particular 1 THHN Application Are:

  • Large Residential Feeders: For upscale homes with high electrical demand.
  • Commercial Building Feeders: Distributing power in commercial buildings.
  • Industrial Equipment: Supplying power to large industrial machines that demand substantial current.

 1 THHN THWN-2  Construction:

Conductor:

THHN THWN-2 conductors are constructed of annealed soft copper that follows ASTM B3 and ASTM B8 standards. 

Insulation:

The cable is insulated with a thermoset plastic jacket (PVC) that is flame-retardant, sunlight-resistant, lead-free, strong, and stable. Without being too bulky, it ensures that the cable can be used in harsh conditions. The jacket is color-coded in accordance with ICEA Method 4.

 1 THHN THWN-2 Standards:

  • ICEA S-73-532
  • UL 1277 (Resistant to flame, moisture, and sunlight)
  • UL 1581, UL 83, UL 163 , UL 758
  • A-A59544
  • ASTM B3 and B8 conductor
  • ANSI/NFPA 70 for Safe Electrical Design and Installation

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.
