[Elecraft] K3 PowerPole connector

[john at kk9a.com]

This is good advice. I have installed Powerpole plugs without the  
crimper however the crimper is a nice tool to have. You can purchase  
custom cables already made from Powerwerx of you don't wish to make  
them.  The 30 amp plug is adequate however the 45 amp plug will allow  
using a larger conductor. To minimize voltage drop you should use a  
very large cable, I use 8 awg when my power supply is set up on the  
floor.

Are you replacing the connector that plugs into the K3 or are you

If the part that is built into the K3, I would strongly suggest  
getting the part direct from Elecraft.  These have to be securely  
mounted within the radio.

If the part that connects, note the following:

PowerPole connectors come in sizes according to the current amperage  
required for the particular circuit.

Anderson PowerPoles consist both of the red and black housing and the  
crimp connectors for the wires.

The housing size used in the K3 is the standard size that will fit  
both 15, 30 and 45 amp crimp connectors.   You choose the connector  
that fits the particular wire size.   30 amp capacity circuits are  
adequate to power the K3 and should be used.

Unless you purchase pre-assembled connectors you will also need a  
crimp tool to crimp the connectors to the wires.   There is also a  
small learning curve on how to crimp and insert the crimped wires into  
the housings.

I would get the parts you need from a company such as Powerwerx.  They  
can help with any connections.

I am looking to replace the powerpole connector on my K3.  Am I  
correct that these 30 amp ones on fleabay are the ones I need?  Thanks  
for any help!  Lee
