Perfect to make extension cords
Size: 20FT, Style: 16AWG-3C
I have several portable tungsten work lights on stands. They product a high level of light which is great for work in a place without adequate lighting. I can move the lights around and get the best lighting. The problem is that they have short cords. This wire, the 16AWG (with the addition of a plug and a receptacle) will solve that problem. The outer jacket is rugged enough to handle daily use and it is light enough that it is not a bother to carry several to the work site. With a rating of 13.1 amps it maybe a little light to use as a replacement cord for power tools, but this wire does come in several other sizes including 14AWG which should work on most tools.

nice 3 strand 16 gauge wire
Size: 20FT, Style: 16AWG-3C, Size: 20FT, Style: 16AWG-3C
This review is for a 20 foot sample of 3 stranded 16 gauge wire. 300V capacity. Using a multimeter, I got a resistance reading of 0.2 ohms across each of the three strands (at roughly 68 degrees Farenheit). Specs say 26 strands of 0.254 mm Tinned copper wire are inside each cable. Good flexibility in the covering.
