Sj Cord sjo12/4blkstr300v250s 12 Awg 4C 300V Portable Cord 250 Ft

Product Description

The SJ CORD sjo12/4blkstr300v250s is a light-duty portable cord built to SJOW and SJO standards, supplying reliable electrical connectivity in demanding field and job-site environments. This cord features 12 AWG copper conductors with a 65-strand configuration for flexibility, four conductors total, and a 300-volt rating. The EPDM rubber insulation provides strong resistance to oils, water, and abrasion, making it well suited for outdoor and industrial portable power applications. Licensed electricians and electrical contractors are the primary installers of this product, typically for portable equipment hookups, temporary power runs, and extension assemblies.

This portable cord is appropriate for light-duty use in residential, commercial, and light industrial settings where a flexible, weather-resistant power supply conductor is required. The SJOW designation indicates suitability for outdoor use with oil-resistant jacket properties, and the SJO designation covers indoor and outdoor applications under standard portable cord guidelines. The 250-foot coil length supports longer runs without splicing, and the black jacket is standard for general-purpose portable cord installations.

Key Features

• 12 AWG stranded copper conductors with 65-strand flexibility for repeated bending and coiling
• EPDM rubber insulation rated for oil, water, and abrasion resistance
• 300-volt rating suitable for light-duty portable power applications
• Four-conductor configuration supports grounded equipment and multi-wire loads
• Temperature range of -40 to 90 degrees C for cold-weather outdoor use
• 250-foot coil length reduces the need for spliced runs on longer jobs

Compatibility

Designed as an SJOW and SJO type light-duty portable cord for use with portable tools, temporary power assemblies, and flexible wiring applications requiring a 12 AWG 4-conductor 300-volt rated cord.

Installation Notes

Installation and termination of portable cord should be performed by a licensed electrician in accordance with NEC Article 400 guidelines for flexible cords and cables. De-energize all circuits before connecting or terminating the cord. Avoid sharp bends, pinch points, and contact with surfaces that exceed the cord temperature rating. Inspect the jacket and insulation for damage before placing the cord into service.
