[QUOTE="Brian jojade, post: 205140, member: 211"] The survey respondent that said they just tin the ends of the wire before using the screw connection should be advised that it is a BAD idea to tin wires that are going to be used in a mechanical connection. While it can make it easier to assemble the cable, a tinned wire will eventually loosen over time and fail. When you fully tin a multistrand wire fully, the solder wicks between the strands of copper and forms a solid block, part of whose volume is metallic solder. When you clamp the solder and copper bundle you tighten the screw or clamp against the solder block, and in time the solder metal "creeps" under the compressive forces and the join loses tension. The wire can then either pull out or cause a high resistance connection with heating. [/QUOTE]
