Hi everyone. Any pointers when installing a 3 way manual transfer switch as part of my solar setup for our 50A 390 what guage wire I should be using on the switch. 10AWG works well but 6AWG does not.

Thoughts?

6 AWG is pretty standard for 50A service. I think I saw this posted on Facebook as well and I agree with one response that use of THHN wire to be helpful for this use. Be sure to used "stranded" THHN.

I ordered some of this to do some coach wiring for an upcoming project.
