The spec sheet for the Anderson PowerPole Family shows an average 2-5
lbf for mating/unmating force for a single connector. But frankly, I
didn't understand their use of the terms High Force and Low Force
wire/PCB. Nevertheless, a pair should be 4-10 lbf.

I measured a dozen of the APP pairs in my shack and came up with 64 ozf
average for a pair using a fish scale. The highest was 66, the lowest
was 60 oz. That's an average of 4 lbf for a pair so it's in the ballpark
of expectations.
I don't have a problem with accidental separation, but sometimes the
wire clutter behind the rigs gets a little dense with time and if I have
to pull a rig out, my fumbling behind the rig can dislodge something.
I set up all my non-APP rigs with a small dongle about 3 inches long
that terminates in a an APP pair at one end and whatever the rig needs
at the other. Then I made up two sizes of extensions with APP pairs on
both ends. So every piece of 12 volt equipment in the shack terminates
in an APP dongle that can plug into my standard APP extensions to reach
the two RigRunners at the rear edge of the operating desk. No more
accidental disconnects except right at the non-APP rigs where the radial
power connectors are. Those I can easily find and reconnect if they happen.
Some day I'm going to get brave enough to convert the K1 and K2s to
panel mounted APPs like the KPA100 but that day isn't here yet.
The only time I've had problems with APPs is with really thick wire.
What happens is moving the rig against two thick wires puts lateral
forces on the APP pair and it eventually wiggles free. The answer is to
properly size the wire for the rig. You don't need 75 amp connectors on
a K2/100 or K3/100.

10 Lbs? Ive used APP for years and I am quite satisfied the whole
shack is done that way. however Ive never had one set strong enough
that I think could dangle the weight of the K3 let alone a full
10lbs what am I doing wrong?

Jack,
The most common cause for that condition is that the connector blades
have not been inserted into the APP body far enough.
Look at the end of the connector assembly - if you can see the tip of
the spring finger under the contact blade, then the blade has not
been fully seated - give it a push with a small screwdriver and it
should snap into place.
A properly constructed APP connector takes about 10 pounds of force
to remove it.

Hi
Just finished building the basic K3 (sub rx and 100w PA awaiting
installation).
Total build time was about 10 leisurely hours spread over a week.
Throughout the entire build I have only found one small issue which
I find remarkable! Hats off to Elecraft.
Anyway, my issue is the Anderson power connector doesn't firmly
latch onto the connector on the rig. It fits on and powers the rig
but pulls off very easily. Have I installed it incorrectly maybe?
