Ask PYS: Power

Terry, on May 29, 2013 asked:

What do you think about this 50 AMP/125V shore power cable? I cut the end off to fit a smart plug but I cannot find any copper cable. Is this junk?

Totally junk. Unfortunately many manufacturers of AC shoreside molded cable are fabricated with untinned wire. As such, their service life is shortened. I'd certainly recommend replacing the cable and getting a new one without the corrosion.
