I recently used a heavy guage cable (#8 stranded, I believe) between the K3 and PS in a portable operation. The extra stiffness of the cable caused a strain that fractured the plastic shell on the positive Power Pole connector in the K3. So, I agree that some sort of strain relief is in order if larger/stiffer cable is used. Perhaps the pig-tail mention earlier is a reasonable approach.
Fortunately, I was able to replace the Power Pole plastic shells without disassembling the K3. It required: 1) removing both the positive and negative shells using a small tool to lift the metal connector blades inside, 2) mating a new pair of connector, 3) scraping off a small protusion on the positive connector to allow the assembly to fit in the rear panel opening, and 4) sliding the assembly over the connector blades. Perhaps this will help if someone else encounters this problem.
