Southwire 04188 Tri-source Extension Cord 12/3 Sjtw 50 Ft

Product Description

The SOUTHWIRE 04188 is a 50-foot, 12/3 SJTW tri-source extension cord designed for heavy-duty power distribution on job sites and in temporary power applications. The cord terminates in a three-way lighted power block, giving trades a compact way to split a single circuit into multiple outlets without adding a separate power strip or distribution box. The 12 AWG conductors handle the current demands common in tool-heavy environments, while the SJTW-rated vinyl jacket resists moisture, abrasion, and UV exposure for outdoor and semi-sheltered use. Reinforced blades reduce the risk of bending or breakage during repeated connect-disconnect cycles.

This cord is suited for residential construction, commercial remodeling, and industrial service work where temporary power distribution is needed at a single drop location. Electricians, general contractors, and field service technicians reach for this type of cord when running temporary power to multiple tools or work lights from a single receptacle. The 50-foot length provides enough reach to serve multiple workstations from a single circuit, reducing the number of individual cords routed back to a panel or generator.

Key Features

• Tri-source three-way power block with lighted end for outlet confirmation
• 12/3 SJTW rating suitable for outdoor and wet-location temporary use
• Vinyl jacket resists moisture, abrasion, and prolonged sunlight exposure
• Reinforced blades help prevent bending or breaking under repeated use
• Heavy-duty strain relief at cord connections for extended service life
• 50-foot length supports multi-tool setups from a single circuit drop

Compatibility

Designed as a standard 12/3 SJTW multi-outlet extension cord suitable for use with 120-volt tools, work lights, and portable equipment requiring temporary power distribution on job sites.

Installation Notes

Installation and use should comply with applicable NEC requirements for temporary wiring, including ampacity limits for the connected load. Inspect the cord and blades before each use and do not operate with damaged insulation or bent blades. Do not exceed the ampacity rating of the 12 AWG conductors when distributing load across the three outlets. Keep the cord uncoiled during use to prevent heat buildup and avoid running the cord under foot traffic, through doorways, or over sharp edges.
