K3 PowerPole connector

[Lee Trout]

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

Are you replacing the connector that plugs into the K3 or are you replacing the part built in to the K3?

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.

Lee,

Unless you can be assured that they are genuine Anderson PowerPoles, I
would hesitate to buy them.  Buy real ones and save yourself buyers
remorse from inadequate contact area and the resulting voltage drop with
higher current.

If they do not have a "A" embossed on the tip of the housing, they are
not genuine.

73,

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.

#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.

I use #8 stranded THHN and the larger pins, but cut enough strands of
the #8 that it fits in the pins.

I use #10 all copper which just fits the 30 amp if you twist them really neatly. It takes several tries to where no strands get away.
We might warn folks about the copper clad aluminum that’s going around if you don’t read carefully.

I suggest using automotive primary wire, #10 AWG for power cables.   It
is stranded with much finer / smaller wire than THHN and is much more
flexible than THHN.    It does correctly fit the 30 amp PowerPole
connectors thus no splicing is needed or as suggested.

I also recommend not only correctly crimping the PowerPole pins but
carefully flow solder into the sleeves.   Likewise on the other end, the
correct size ring terminal should be used, crimped and soldered, for the
power supply connections.

The transceiver power should come direct from the power supply, thus
avoiding any DC distribution panels.

Bob, K4TAX
