The wire nut meltdowns in my transfer switch, IMO were due to stranded wire pigtails being wire nutted to solid copper romex wire. When tighten down on the stranded wire wrapped around the solid wire, the wire nut cuts thru the strands, making a loose connection and less current capacity. I removed the pigtails, connected the romex directly to the switch lugs with a needle nose pliers made round eye. If I had used the stranded pigtail, I would have wet it out with solder first to make it more solid. Much easier though, to remove the pig tails.
