8 AWG THHN/THWN-2 – Dependable Capacity for Large Branch Circuits and Equipment Feeders
This 8 AWG THHN/THWN-2 copper building wire is designed for circuits that draw more current than smaller gauges can safely carry. It is commonly used for large branch circuits, equipment connections, and feeders in commercial and industrial settings. The pure copper conductor ensures efficient power delivery. PVC insulation with a nylon jacket provides protection against abrasion and moisture. UL83 certified with a 600V rating. The THWN-2 rating allows installation in wet or damp locations. Stranded construction is recommended for conduit runs with bends. Solid is acceptable for shorter, straight installations.

FAQ

 

What is the ampacity of 8 AWG at 75°C?
Approximately 50A at 75°C termination temperature. Always check the termination rating before final sizing.
Does 8 AWG require special bending tools?
Hand bending is possible but requires effort. Use a bender for sharp 90-degree bends to prevent kinking.
Is 8 AWG available in stranded and solid?
Yes. Stranded is more common for longer runs, but solid is available for shorter installations.
Can 8 AWG be used for outdoor equipment connections?
Yes, provided it is rated THWN-2 and installed in appropriate conduit suitable for outdoor conditions.
