Other Names for 250 MCM THHN THWN-2 Copper Building Wire:

250 MCM Copper wire, 250 MCM building cable, 250 MCM hook up wire, 250 MCM conduit wire, 250 MCM nylon wire, 250 MCM construction cable, 250 MCM thermoplastic-insulated copper wire, 250 MCM THHN-PVC tray cable, 250 MCM "spaghetti" wire.

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 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 cable is rated at 600 V.

Features:

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, such as direct burial. The jacket is color-coded in accordance with ICEA Method 4.
