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

Photovoltaic Cable LLC offers UL4703-certified 10 AWG Copper PV Wire rated at 2,000 Volts — the most widely specified size for residential and commercial solar installations across the USA. Available in Black and Red, in four reel lengths: 500, 1,000, 2,500, and 5,000 feet. All inventory ships same day from our three U.S. fulfillment centers.

Why 10 AWG is the most popular size

10 AWG strikes the ideal balance between current capacity and handling ease for most residential string configurations. It carries up to 30A continuous DC current, fits standard MC4 connectors, and routes easily through conduit and raceways. Whether wiring a 10-panel rooftop system or a mid-size ground-mount array, 10 AWG 2000V is the go-to specification for solar installers nationwide.
