TEMCo 10 AWG Solar Cable 100 ft - Made in USA, Direct Burial

In this review of the TEMCo 10 AWG solar cable, the bottom line is simple: it is a solid choice for DIY solar installs and small to medium PV runs where durability and pure copper conductors matter most. The reviewer found the 100 ft spool useful for array-to-combiner and panel-to-inverter runs and appreciates that the cable is made in the USA and meets UL 4703. For anyone who needs a reliable, direct burial rated PV wire with clear electrical ratings, this cable delivers dependable performance without unnecessary frills.

Key Features

• Made in the USA: Built to domestic manufacturing standards, the cable gives buyers confidence in consistent quality and traceability.
• 19-strand pure copper: The multi-strand conductor provides reliable conductivity and enough flexibility for routing around panels and conduits.
• 600 VDC, 50 amp rating: These electrical ratings make the wire suitable for most residential and small commercial PV circuits without overspecifying the run.
• XLPE insulation: The insulation is rated for direct burial and a wide temperature range, protecting the conductor in outdoor and underground installations.
• Durable dimensions: With a nominal outside diameter of 0.230 in and roughly 17.54 ft per pound, the physical size is manageable for typical solar cable terminations and connectors.

Who It's For

The TEMCo 10 AWG solar cable is aimed at homeowners, installers, and hobbyists wiring residential or small commercial solar arrays who want a US-made, UL-certified PV wire for outdoor runs and burial. It is particularly well suited for those who value a pure copper conductor for conductivity and long-term reliability.

Those who need extremely high flexibility for very tight bends, micro-run wiring inside enclosures, or specialty thin-profile cable should consider alternate wire types designed for that purpose, but for standard rooftop, ground-mounted, and combiner connections this cable is a practical choice.

Pros & Cons

Pros

• Made in the USA construction provides consistent build quality and manufacturing standards.
• Pure copper, 19-strand conductor ensures good conductivity and reasonable flexibility for installation.
• Direct burial rated XLPE insulation and a wide temperature range improve long-term outdoor performance.

Cons

• Not the most flexible PV wire available; users reported it can be stiff compared with thinner stranded options.

Our Verdict

The TEMCo 10 AWG solar cable is a practical, value-oriented choice for standard PV runs where a UL 4703-certified, direct burial, pure copper conductor is required. It is best for homeowners and small installers who want a dependable 100 ft spool made in the USA; those needing ultra-flexible cable for tight spaces should weigh that trade-off.

Frequently Asked Questions

Is this cable suitable for underground burial?
Yes. The XLPE insulation and direct burial rating mean it can be buried without additional conduit in typical PV installations.

Can this wire handle inverter connections?
With a 600 VDC and 50 amp rating, it is suitable for many residential inverter and combiner applications within those limits.

Is the conductor copper or copper-clad aluminum?
The conductor is 19-strand pure copper; there is no CCA used in this product.
