PowerPoles s way to prevent from plugging them in wrong

[Elecraft mailing list]

I few day ago someone had posted how the plugged in the power cord wrong (moved over 1 position)
on his K3 and wound up damaging the connector when the shorted the + Supply to the Neg PowerPole.


Note: It's a good Idea to fuse the power cord so that the fuse will blow if this happens.

A simple preventative measure to prevent the cord from being plugged in the wrong way would
be  to simply stick a stick on rubber foot on each side so that the plug will not go in if it's moved
over by one position.


When I build my distribution boxes I recess the PowerPoles. This physically protects
the PowerPole as well as protecting from the possibility of plugging the cable in wrong.

Heck,  it is an even better plan to just turn off the power supply
before making any such connection,  whether it is a computer, radio, or
accessory.

But, shoot, this could happen to anyone in a hurry or in a moment's
distraction.  My most frequent connectivity faux pas is to confuse the
little computer mic plug with the earphone plug, and wonder why I don't
hear anything...    ;-)


It took a huge dose of humility for a guy with his
credentials to tell us that story.

Just MY take.   Happy trails!
