Low-Voltage Extension Cord (12V–48V)

Built-tough low-voltage extension cords with NEMA plugs and receptacles, rated for 12V–48V DC applications. Rugged SOOW/SJEOW jackets, copper conductors, and secure connectors. Available in popular gauges and lengths.

Low voltage doesn’t mean light-duty. These NEMA-style low-voltage cords are engineered for 12V–48V systems that demand reliability in harsh conditions. Whether you’re powering LED work lights, low-voltage pumps, or DC equipment, these cords are jobsite-tough and built to last.

Each cord is constructed from high-strand copper conductors for minimal voltage drop, wrapped in a SOOW or SJEOW jacket that resists oil, water, abrasion, and UV exposure. Unlike generic cords, these are built to take abuse on construction sites, shipyards, and industrial plants.

Fitted with standard NEMA straight-blade or locking plugs, these cords make it easy to connect to low-voltage power sources without adapters or special connectors. With lengths up to 100 ft and gauges from 16 AWG to 10 AWG, they deliver reliable performance where lighter cords fail.

These aren’t hobby cables — they’re field-ready power cords for real industrial work.

1. What are these cords used for?

They’re designed for low-voltage equipment including LED lighting, pumps, RV systems, and DC tools that require rugged NEMA-style cords.

2. What voltage range do they support?

They’re built for 12V to 48V DC systems. Always confirm your equipment’s voltage before use.

3. Why use NEMA plugs for low-voltage?

NEMA connectors are familiar, rugged, and secure. They make it easy to connect low-voltage gear without special adapters.

4. What gauges are available?

Options range from 16 AWG (light-duty) to 10 AWG (heavier loads). Larger gauges are available for higher current runs.

5. What lengths are available?

Cords are offered from 10 ft up to 100 ft. 25 and 50 ft are the most common jobsite lengths.

6. Can these cords be used outdoors?

Yes. SOOW and SJEOW jackets are weather, oil, and UV resistant, built for rugged outdoor use.

7. What’s the difference between straight-blade and locking plugs?

Straight-blade plugs are standard household-style. Locking (L-series) plugs twist into place, preventing accidental disconnects.

8. Are these cords UL/CSA certified?

Yes — all cords use UL/CSA certified components for safety and compliance.

9. Do these cords work with inverters or RVs?

Yes. They’re frequently used in RV, marine, and inverter setups where low-voltage DC power is required.

10. Are these cords made in the USA?

Yes — assembled in the USA with heavy-duty materials for industrial reliability.
