[Elecraft] K3 PowerPole connector

[Don Wilhelm]

#10 or #8 wire will need the 45 amp contact blades.

However, if the purpose is to minimize voltage drop, there is no need to 
use the larger connector - construct the power pole with #12 wire about 
3 inches long.  Then splice onto that with #10 or #8 wire for the rest 
of the run to your power supply.
