8 AWG PV Wire 2000V UL4703 | Copper Solar Cable | Made in USA

8 AWG PV Wire 2000V UL4703 — Made in USA | In Stock | Ships Same Day

Photovoltaic Cable LLC offers UL4703-certified 8 AWG Copper PV Wire rated at 2,000 Volts — the preferred size for string-to-combiner connections, medium and long DC runs, and commercial rooftop installations where higher current capacity is required. Available in Black and Red, in 500 ft and 2,500 ft reels. All inventory ships same day from our three U.S. fulfillment centers.

Why choose 8 AWG over 10 AWG

8 AWG carries up to 40A continuous DC current — significantly more than 10 AWG — making it the right choice when your string current exceeds 30A, when runs exceed 100 ft, or when you need to minimize voltage drop in longer DC feeder runs. It is also commonly specified for combiner box to inverter connections in commercial and ground-mount systems. Use our Voltage Loss Calculator to determine if 8 AWG is the right gauge for your project.

Frequently asked questions

When should I use 8 AWG instead of 10 AWG?
Use 8 AWG when your string current exceeds 30A, when your DC run exceeds 100 ft, or when your voltage drop calculation requires a larger conductor. Our Voltage Loss Calculator will confirm the right gauge for your project.

Is this wire rated for direct burial?
Yes. UL4703-listed PV wire is rated for direct burial, conduit, and free-air installation per NEC Article 690 guidelines.
