Southwire 04189 Tri-source Extension Cord 12/3 Sjtw 100 Ft

Product Description

The SOUTHWIRE 04189 is a 100-foot, 12/3 SJTW Tri-Source extension cord with a three-way lighted power block at the outlet end. Designed for job-site and trade use, it delivers distributed power across multiple outlets from a single cord run. The 12 AWG, 3-conductor construction handles demanding loads, while the SJTW-rated vinyl jacket resists moisture, abrasion, and UV exposure for reliable outdoor and indoor service. Reinforced blades reduce the risk of bending or breakage during repeated plug-and-unplug cycles, and a heavy-duty strain relief at the outlet block protects internal connections and extends service life.

The 04189 is suited for construction sites, HVAC service calls, electrical rough-in work, and any application requiring power distribution from a single circuit drop. At 100 feet, it gives tradespeople the reach needed to work across large floor plates or equipment rooms without additional cord sets. The lighted end provides quick visual confirmation that the circuit is live before connecting tools or equipment.

Key Features

• Three-way Tri-Source power block with lighted end for circuit confirmation
• 12/3 SJTW construction rated for wet, outdoor, and UV-exposed environments
• Reinforced blades resist bending and breakage under repeated use
• Heavy-duty strain relief at outlet block protects conductor terminations
• 100-foot length reduces the need for additional extension cord sets on large job sites

Compatibility

Designed as a general-purpose 12/3 SJTW extension cord compatible with standard 15-amp and 20-amp (with appropriate adapter) grounded outlets and power tools commonly used in electrical, HVAC, and construction trades.

Installation Notes

Licensed electricians and general tradespeople install and use extension cords of this type in accordance with NEC Article 400 guidelines for flexible cords and cables. Always verify the connected load does not exceed the cord's current-carrying capacity before use. Inspect the jacket, blades, and strain relief before each use and remove from service if damage is found. Do not use as a permanent wiring substitute.
