SPT-2 Wire features a thicker insulation than SPT-1 Wire at .045” thick. As a result, SPT-2 also has a higher maximum amp rating, and is able to handle more power.Because of its thicker insulation, SPT-2 cord is often recommended for lower temperatures where the insulation may get brittle and crack. However, the thinner insulation on SPT-1 wire tends to be more pliable, so some professional installers believe that SPT-1 is actually better for cold weather.
