TEMCo 10 AWG Solar Cable 80 ft Red - Made in USA Industrial

In this review the TEMCo 10 AWG PV solar cable is examined for homeowners, installers, and DIY solar enthusiasts who need a reliable, direct burial rated conductor. The bottom line: this cable is worth considering when pure copper construction, the ability to handle 600 VDC, and broad temperature tolerance matter most. Our review finds the standout reason to buy is the 19-strand pure copper conductor and XLPE insulation that together provide durable outdoor performance without the compromises of copper-clad alternatives.

Key Features

• Made in the USA: Manufactured domestically to US quality standards for consistent material and assembly control.
• 19-Strand Pure Copper: Solid copper strands give reliable conductivity and semi-flexible handling for easier routing in arrays and conduit.
• Electrical Ratings: Rated 600 VDC and 50 amps, suitable for many residential and small commercial PV circuits.
• XLPE Insulation: Cross-linked polyethylene resists heat, UV, chemicals, and abrasion for long-term outdoor exposure.
• Direct Burial Rated: Can be used above ground, in conduit, or buried without additional jacket, simplifying installations.
• Temperature Range: Operates from -40C to 90C so it tolerates cold starts and hot, sunny rooftop conditions.

Who It's For

The TEMCo 10 AWG cable is best for solar installers, hobbyists, and property owners building small to mid-size PV systems who prefer American-made materials and want the conductivity of pure copper. It's a practical choice when a 600 VDC rated, direct burial capable conductor is needed for runs between panels, combiner boxes, and inverters.

Those who need ultra-high flexibility for repeated movement or extremely tight bends may prefer a different stranded construction designed for maximum pliability. Also, buyers requiring very thin or specialty-jacketed PV wire should look at purpose-built alternatives.

Pros & Cons

Pros

• Pure copper 19-strand conductor for dependable conductivity and longevity.
• XLPE insulation provides strong resistance to UV, heat, and chemicals for outdoor use.
• Direct burial rating and 600 VDC capability simplify many installation scenarios.
• American manufacture offers traceability and quality peace of mind.

Cons

• The cable is semi-flexible rather than highly flexible, which some users describe as somewhat stiff when uncoiling long lengths.
• Heavier gauge and tight coiling can lead to tangles on first use if not carefully handled.

Specifications

Our Verdict

The TEMCo 10 AWG solar cable is a sensible, value-oriented choice for residential and light commercial PV work. Its pure copper conductor, UL 4703 compliance, and robust XLPE jacket make it a durable option for direct burial or conduit use, and it represents good value for those prioritizing longevity and American manufacture over maximum flexibility.

Frequently Asked Questions

Is this cable safe for burial?
Yes, the cable is direct burial rated and designed for underground installation without additional protection when used per local code.

Can I use this for inverter input wiring?
The 600 VDC and 50 amp rating suit many PV runs; confirm system voltage and ampacity needs before using this 10 AWG cable for inverter inputs.

How flexible is the wire?
The 19-strand copper gives semi-flexible handling; it is not ultra-flexible and may feel stiff on long, tightly coiled lengths.
