TEMCo 10 AWG Solar Cable 150 ft - Made in USA PV Wire

In this review the TEMCo 10 AWG PV solar cable earns its place for installers and DIYers who need a straightforward, rugged conductor for photovoltaic systems. The single biggest reason to buy is that it is a Made in the USA, 19-strand pure copper PV wire that meets UL 4703 and is direct burial rated, which makes it a reliable, code-friendly choice for array runs and outdoor wiring. The review focuses on real-world handling, electrical ratings, and the build quality that matters during installation.

Key Features

• Made in the USA: Manufactured domestically to consistent quality standards so buyers get a traceable PV cable for solar installations.
• 19-strand pure copper: The stranded copper conductor delivers reliable conductivity and enough flexibility to route through trays and conduit without using CCA.
• 600 VDC, 50 amps rating: Electrical ratings suit many residential and small commercial PV circuits when sized correctly.
• XLPE insulation: Cross-linked polyethylene resists heat, UV, chemicals, and abrasion for long-term outdoor exposure.
• Direct burial rated: Can be run above ground, in conduit, or buried without additional inner conduit protection where local code allows.
• Physical dimensions: Nominal outside diameter of 0.230 in and about 17.54 ft per pound, providing a tangible sense of heft during installation.

Who It's For

This cable is best for solar installers, electricians, and serious DIY homeowners who prioritize a pure copper conductor and a UL 4703 certified PV wire that can be buried or run outdoors. It suits typical residential arrays and many small commercial applications where a 10 AWG conductor and 600 VDC rating are sufficient.

Those needing ultra-flexible, lightweight wire for tight bends or very long DC runs should look at alternative gauge or stranded constructions; likewise projects requiring higher ampacity or voltages must specify a larger gauge or different cable type.

Pros & Cons

Pros

• American-made construction and UL 4703 compliance provide confidence in safety and traceability.
• Stranded pure copper offers dependable conductivity and practical flexibility for routing.
• XLPE insulation and direct burial rating mean it handles outdoor exposure and underground runs without extra protection.
• Clear electrical ratings (600 VDC, 50 A) simplify system planning for typical PV circuits.

Cons

• Not the most flexible 10 AWG cable; some users report it is semi-stiff and can tangle when uncoiled.
• Thicker gauge and weight may be cumbersome on very long runs compared with lighter alternatives.

Frequently Asked Questions

Is this cable suitable for underground burial?
Yes. The wire is direct burial rated and may be buried without additional inner conduit where local code permits.

Can it be used for 600 V systems?
Yes. The cable is rated to 600 VDC, so it is appropriate for many PV system configurations within that voltage limit.

How flexible is the 10 AWG TEMCo wire?
It is semi-flexible due to the 19-strand construction and pure copper; easier to route than solid wire but not as supple as finer-stranded alternatives.
