Not going to get into pro-cons of PP but I have encountered issues
trying to use No.10 zip cord from Powerwerx. Not a fault of the wire
but insulation size is too big for many connectors. Wire is great
from them - just wish shipping was cheaper.
So I ended up using a short piece of No. 12 installed in the
connector and splicing the No.12 to the No.10 wire. You can use
yellow butt splices which crimp or do as I prefer, which is doing a
soldered lap junction covered with heat shrink.
Voltage drop in a couple inches of the smaller gauge wire is
insignificant (probably unmeasurable) but make life easier when
assembling high-current power cords.
BTW the old four pin mic connector remains my power connector of
choice. The are cheap and do not separate as they have threaded
collar. Use male pins in the panel receptacle and female pins in the
plug. I found a source of them from MCM Electronics. That is what I
installed as Power/PTT connector on my 2M80 2m linear amps. Supplied
with 4-foot of No.10 red/black zip to reduce voltage drop when drawing 15 amps.
My fancy-dancy plastic power connector failed on my DEMI transverter
so I installed a 4-pin mic jack and plug. Unit is working great,
again. Original socket melted under current load for the 50w
transverter. DEMI now uses something different with no issues seen
by me with those. The units using the black connector dated from 2010-11.

Subject: Re: [Elecraft] K3 and Power Poles
On the topic of Power Pole connectors, I have a crimper that if I
remember correctly I bought from West Mountain Radio. It looks pretty
similar to the one sold by Powerwerx. I have had very little success
crimping the #10 zip cord sold by Powerwerx. Am I missing something?
