I'm looking for a general consensus on the joining of two stranded wires...I've been doing electrical work for a good couple of years. I started a new job and in the last month I've found three people that believe that you should twist the wires (with your Klein's) prior to making a wire nut joint. I'm personally appalled!!!!!! I believe I've been well trained and I was always told your Klein's should never touch the copper prior to joining the joint. What's your thoughts???
