Arrived on a spool. Measured 25 feet as advertised. I expected it could be a little short but it was perfect. Good quality. Review: Great value & ease of installing into 1/2 inch conduit (EMT) - Pros: Great value, much less expensive than buying from the big box home improvement stores. My roll of # 12/3 Gage had a generous couple of feet extra which is a plus. Cons: The copper conductors felt a bit small on my Klein wire strippers for the #12 Gauge slot, so I decided to measure the copper wires. The outside diameter of all the conductors were 0.0028" under size at 0.078', (specs 0.0808') using both a Starrett micrometer & vernier calibers. Don't know if I had a bad roll. Since this installation was for much lower wattage circuit, it was not an issue. YMMV. Overall a very good buy. ## Features - 12 AWG commercial wiring for outlets, switches and other loads - #12 THHN comes stranded/solid with variety of colors and lengths - 12/3-Gauge THHN wire contains copper (CU) conductors - THHN is rated for 600-Volt ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6WLRW9W | | Brand | Southwire | | Brand Name | Southwire | | Color | Green,White | | Colour | Green,White | | Customer Reviews | 4.8 out of 5 stars 141 Reviews | | Gauge | 12 | | Global Trade Identification Number | 00032886703249 | | Included Components | 25 ft. 12/3 Black/White/Green Solid CU THHN Tri-Wire | | Manufacturer | Southwire | | Material | Copper | | Material Type | Copper | | Model | 59318203 | | Number Of Wires | 3 | | Number of Items | 1 | | Number of Packs | 1 | | Number of cable strands | 3 | | Part Number | 59318203 | | Strands | 3 | | UPC | 032886703249 | | Unit Count | 1 Count | | Voltage | 600 Volts | ## Product Details - **Brand:** Southwire - **Colour:** Green, White - **Gauge:** 12 - **Material:** Copper - **Number of cable strands:** Multi-Strand ## Images ![25 ft. 12/3 Black/White/Green Solid CU THHN Tri-Wire - Image 1](https://m.media-amazon.com/images/I/51V6jkcvJWL.jpg) ![25 ft. 12/3 Black/White/Green Solid CU THHN Tri-Wire - Image 2](https://m.media-amazon.com/images/I/71bYFSL6xSL.jpg) ![25 ft. 12/3 Black/White/Green Solid CU THHN Tri-Wire - Image 3](https://m.media-amazon.com/images/I/71gEGqn45zL.jpg) ![25 ft. 12/3 Black/White/Green Solid CU THHN Tri-Wire - Image 4](https://m.media-amazon.com/images/I/71-YxhJ1SbL.jpg) ![25 ft. 12/3 Black/White/Green Solid CU THHN Tri-Wire - Image 5](https://m.media-amazon.com/images/I/81-vnaaWkqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 25 feet *by Y***E on 12 July 2026* Great deal on wire.
