Southwire so4/3blkstr600vmr Soow 4/3 Flexible Cord

Product Description

The SOUTHWIRE so4/3blkstr600vmr is a SOOW-rated 4/3 flexible power cord built for demanding electrical service applications. It carries three conductors — black, white, and green — in a black outer jacket rated at 600 volts. The conductors are stranded copper, which provides the flexibility needed for portable tools, generators, temporary power distribution, and industrial equipment connections. This cord is sold cut to length, making it suitable for custom runs where a fixed-length product would not meet jobsite requirements. Licensed electricians and industrial maintenance technicians are the primary installers of this type of flexible cord assembly.

SOOW flexible cord is a standard choice for portable and semi-portable electrical equipment in commercial and industrial environments. The 4 AWG conductor size handles higher-amperage loads, and the three-conductor configuration supports hot, neutral, and ground wiring for grounded equipment. Typical applications include temporary power drops on construction sites, portable compressors, welding equipment feeders, and stage or event power distribution. The oil-resistant and weather-resistant outer jacket of SOOW-rated cord makes it appropriate for both indoor and outdoor use.

Key Features

• SOOW-rated jacket: oil-resistant and weather-resistant for indoor and outdoor use
• 4 AWG stranded copper conductors for flexibility and high-amperage capacity
• Three-conductor configuration: black, white, and green
• 600-volt rating suitable for commercial and industrial power applications
• Black outer jacket for easy identification and UV resistance
• Cut-to-length format for custom run sizing on the job

Compatibility

Designed as a general-purpose SOOW flexible power cord for use with portable and semi-portable electrical equipment requiring a grounded 4/3 conductor configuration at 600 volts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 400, which governs the use of flexible cords and cables. Disconnect and lock out all power sources before terminating or splicing flexible cord. Stranded copper conductors require appropriate ferrules or terminals rated for stranded wire to ensure a secure connection. Do not use flexible cord as a substitute for permanent building wiring.
