TEMCo Industrial 10 AWG Solar PV Wire 100 ft Red — 19-Strand Bare Copper, XLPE Direct-Burial

TEMCo 10 AWG Solar PV Wire is a 100-foot reel of 19-strand bare copper PV cable with XLPE insulation, UL 4703 certification, and direct-burial rating, made in the USA for solar and DC power applications.

This 10 AWG red photovoltaic (PV) wire is engineered for rooftop and ground-mounted solar arrays, charge controllers, battery banks, and other 600 VDC-rated DC systems. Constructed from 19-strand pure copper (not copper-clad aluminum), the conductor delivers consistent conductivity and the flexibility installers expect when routing cable through trays, conduit, and junctions. The cross-linked polyethylene (XLPE) jacket resists sunlight, moisture, and temperature swings from -40°C to 90°C, making it suitable for exposed and direct-burial installations where long-term durability matters.

Why choose TEMCo 10 AWG PV wire for a solar installation?

This wire balances ampacity, flexibility, and durability for many small- to medium-scale DC runs. With a 50-amp rating at 600 VDC and 19-strand construction, it minimizes voltage drop while remaining easier to handle than solid conductors.

• Pure bare copper conductor — no CCA (copper-clad aluminum) to ensure consistent conductivity.
• 600 VDC rating — suitable for many PV array and battery connections within code limits.
• 50 A ampacity under specified conditions — appropriate for common 10 AWG DC loads.
• Flexible 19-strand design — easier routing and reliable terminations at lugs and MC4 connectors.

How does this wire hold up outdoors and underground?

The XLPE insulation and UL 4703 certification mean the cable is designed specifically for photovoltaic use, including exposure to sunlight and burial when installed per local codes. Temperature and environmental specs make it a dependable choice across varied climates.

• XLPE jacket resists UV, moisture, and chemicals encountered in outdoor placements.
• Direct-burial rated — can be used in underground runs when installed according to local regulations.
• Operational temperature range from -40°C to 90°C for hot summers and cold winters.
• Manufactured in the USA to consistent quality standards and traceability.

What are the electrical and physical specifications I should plan around?

Knowing ampacity, voltage rating, and physical size helps with conduit fill, clamp selection, and voltage-drop calculations. TEMCo supplies clear specs so installers can design safe, code-compliant systems.

• Conductor: 19-strand pure copper, nominal outside diameter 0.230 in.
• Length: 100 feet per reel; weight and handling based on 17.54 feet per pound.
• Ratings: 600 VDC and 50 amps; temperature range -40°C to 90°C.
• Certification: Meets UL 4703 PV wire standard for photovoltaic applications.

How do I install and terminate TEMCo 10 AWG PV wire safely?

Follow manufacturer guidance and local electrical codes for DC circuits. Proper stripping, crimping, and use of PV-rated connectors or lugs prevent overheating and ensure long-lasting joints.

• Strip only the required insulation length and use PV-compatible crimp lugs or MC4 connectors.
• Ensure torque values on terminal blocks and lugs match manufacturer specs to avoid loose joints.
• Avoid sharp bends and kinking; maintain bend radius per code and product data.
• Use appropriate conduit, cable ties, and UV-resistant fasteners for exposed runs.

Who this is for: Installers, EPC contractors, and DIY homeowners planning small to medium photovoltaic systems, battery-based off-grid setups, or DC distribution runs who need a 10 AWG cable with reliable conductivity, weather resistance, and UL PV certification. The TEMCo 100 ft red reel is ideal when you require a durable, American-made conductor for visible positive feed lines, color-coded array wiring, or replacement spools matched to existing equipment.
