100FT 12/4 SJOOW 300V Wire 12 AWG 4 Conductor - Heavy Duty Cable

In this review of the 100FT 12/4 SJOOW 300V Wire the bottom line is straightforward: this heavy duty 12 AWG 4 conductor cable is aimed at technicians and maintenance teams who need a flexible, rugged portable power cord that performs in extreme conditions. The reviewer found the cord especially useful where oil, water, and temperature resilience matters, and the stranded oxygen free copper conductors deliver reliable conductivity over the full 100 ft length. If you need a long run of portable power cable for industrial motor leads, machinery circuits, or data center temporary feeds, this cable stands out for durability and flexibility.

Key Features

• Service, Oil and Water Resistant: The SJOOW jacket tolerates exposure to oils and wet environments so it holds up on shop floors and outdoor sites.
• Wide Temperature Range: Rated for -40C to 90C, the cord remains flexible in cold and stable in high heat, reducing the chance of cracking or stiffness on job sites.
• Stranded Oxygen Free Copper: The stranded pure copper conductors increase conductivity and help the cable carry current efficiently for motor and power circuits.
• 4 Conductor 12 AWG Construction: Four 12 gauge conductors with 67 strands per conductor provide a balance of flexibility and ampacity for portable equipment use.
• Durable Yet Flexible Diameter: The cord's approximately 12.1 mm outer diameter gives robust insulation while remaining easy to route and install.
• Easy to Cut and Install: The cable is straightforward to terminate and dress, which speeds installation of temporary power runs and control circuits.

Who It's For

This cable is best for industrial electricians, rental house technicians, and facilities teams in power generation, mining, oil and gas, marine operations, and data center maintenance who need a 100 ft portable power cable that resists oil, water, and temperature extremes. It is a practical choice for powering portable tools, lighting fixtures, motor leads, and temporary machinery circuits where flexibility and durability matter.

Those who should look elsewhere include installers who require a dedicated grounding conductor in the same jacket (this is not a 4+1 ground cable) or projects requiring higher voltage ratings than 300V. For household branch-circuit wiring or fixed in-wall installations, choose cables listed for building wiring instead.

Pros & Cons

Pros

• Durable SJOOW jacket resists oil and water and functions across a broad temperature range.
• Stranded OFC conductors with 67 strands each provide good conductivity and flexibility for portable runs.
• 100 ft length covers long temporary feeds without splices, useful for motors and site equipment.

Cons

• Does not include an extra ground conductor; it is a 4-conductor cable without a dedicated ground wire.

Specifications

Our Verdict

The 100FT 12/4 SJOOW 300V cable is a sensible, value-focused pick for professionals who need a rugged, flexible 12 AWG 4 conductor portable power cord that holds up to oil, water, and temperature extremes. It is recommended for temporary power, motor leads, and industrial maintenance where a dedicated ground conductor is not required inside the same jacket.

Frequently Asked Questions

Does this cable include a ground conductor?
No. This is a 4-conductor cable and does not include an additional ground conductor; confirm your grounding needs before purchase.

Is the cable suitable for outdoor use?
Yes. The SJOOW jacket is service, oil, and water resistant and rated for -40C to 90C, making it suitable for many outdoor and harsh-environment applications.

Can this cable be used for motor leads?
Yes. The stranded 12 AWG OFC conductors and 300V rating make it appropriate for portable motor leads and similar machinery circuits.
