The following pix show three different techniques for installing wirenuts.

All pix use 2 #12 AWG Solid Conductors from NM-B Cable, the contrasting black and white colors to illustrate the twisting.

The first two pix show the connection made by pretwisting and trimming the conductors, then installing the wirenut hand tight.





The second pair of pix shows using no pretwisting, but using the Ideal WireNut wrench.





The last pair shows the technique of using Wingnuts tightened hand tight, and no pretwisting.





All wirenuts were removed to show the quality of the connection, and the number of twists in the conductors.

Any comments?
