Sj Cord sjo12/4blkstr300vmr Sjo 12/4 Cord 300V

Product Description

The SJ CORD sjo12/4blkstr300vmr is a 12 AWG 4-conductor SJO-rated stranded copper cord supplied on a master reel in black jacket rated for 300 volts. SJO designation indicates an oil-resistant outer jacket suitable for use in industrial and commercial environments where petroleum exposure is a factor. The stranded copper construction improves flexibility compared to solid conductors, making this cord well suited for portable equipment, power leads, and service drop applications. Electricians and maintenance technicians working in manufacturing, HVAC mechanical rooms, and commercial facilities commonly specify SJO cord for demanding portable wiring runs.

This master reel format is intended for bulk installation use where contractors or supply houses cut cord to length as needed. The 12 AWG 4-conductor configuration supports equipment loads requiring a dedicated ground or neutral alongside two current-carrying conductors. Typical applications include power feeds for portable motors, heavy-duty extension assemblies, and wiring of movable machinery in settings where cord flexibility and oil resistance are required by code or site conditions.

Key Features

• SJO-rated oil-resistant outer jacket for industrial and commercial use
• 12 AWG stranded copper conductors for flexibility and current capacity
• 4-conductor configuration supports ground, neutral, and two hot conductors
• 300-volt rating suitable for standard single-phase and low-voltage three-phase portable equipment
• Master reel packaging allows bulk cut-to-length use on the job
• Black jacket for general-purpose identification and UV resistance in indoor applications

Compatibility

Designed as an OEM-style replacement and general-use SJO flexible cord for portable electrical equipment and power assemblies requiring 12 AWG 4-conductor 300-volt rated cable.

Installation Notes

Installation of flexible cord assemblies should be performed by a licensed electrician in accordance with applicable NEC articles governing flexible cords and cables. De-energize all circuits before terminating or splicing cord ends. Verify that connected equipment ratings do not exceed the cord voltage and ampacity ratings. Cord should not be used as a substitute for fixed wiring or routed through walls, conduit, or concealed spaces unless the installation method is explicitly permitted by the authority having jurisdiction.
