- Product Details
80mm² THHN wire is a high performance wire for building and industrial use. It is capable of carrying high currents and is suitable for high load electrical systems. THHN copper wire is made of high-quality thermoplastic insulation covered with a layer of heat-resistant nylon, which is designed to provide excellent electrical performance, as well as stability in high-temperature environments. The insulation is able to withstand prolonged high temperatures of 90°C (in dry environments) and maintains good performance in humid environments up to 75°C.

FAQ
What is the ampacity rating of 80mm² THHN?
At 90°C (standard THHN rating), 80mm² wire is typically rated for approx. 230 to 240 Amps in free air, and derated to around 200 to 215 Amps in conduit (depending on specific local codes like PEC)
Can 80mm² THHN be used in cable trays?
Yes. At this large gauge, 80mm² THHN is typically marked "For CT Use" (Cable Tray). This allows it to be laid in industrial ladder trays without a conduit, provided it is supported and spaced correctly according to code.
How do I terminate 80mm² wire to a breaker?
You must use Compression (Crimp) Lugs or heavy-duty Mechanical (Set-screw) Lugs. The wire is too thick to fit directly into standard molded case circuit breaker clamps unless the breaker is specifically frame-sized for 200A+ lugs.
