Jerry makes a good point. The AC ampacity of wires is not solely sufficient for DC, and is imperfect at longer lengths for AC drops. Consider the voltage is rising and falling at the frequency of the AC potential, while the DC is heating the wire continuously while in use.

I have noticed Kenwood is more generous with their size of cables than some manufacturers. Most hams probably at some point have to custom make their cables for mobile or home applications, so I simply am advocating a conservative cable sizing for ham transceivers.
