Refer to the category markings on your probe assemblies as well as on the add-on accessories (like detachable Caps or Alligator Clips), if any, for applicable rating changes. Quality marine wire, as specified by ABYC standards, will always be stranded rather than solid, and always tin-plated copper. 65 x 10-8 Ω m (0.
