[Elecraft] bad choice: Anderson PowePole connectors

[Leigh L Klotz, Jr.]

Just to elaborate on Sandy's point about 24v for those who don't know, 
you can assemble a pair of APP connectors with one rotated 90 degrees, 
or with them aligned vertically instead of horizontally, and they won't 
fit with the standard 12v ham/ARES configuration, insuring safety.

I don't know if anyone has a standard 24v configuration, but even if 
not, just making your 24v cable up differently means you can't do this.

The one thing you *can* do with APP is offset one from the other and 
plug only the red of one into the black of the other, and if there is 
some other ground path, you can lose.  If the 12vdc pairing used had 
used a 90 degree rotation this would be a lot harder to do, as you would 
have to have the cables rotated *and* colors wrong when you plug them in 
to cause his failure.  As it is, colors wrong and offset by nearly 3/8 
inch is a pretty good indicator, but it can happen in the dark.
