Reverse Polarity Protection - VE3WI Dave - 2023-03-03
Since our modern rigs usually require DC power, there is always the risk that we'll connect positive to negative, maybe releasing some of that magic smoke. Anderson Powerpoles are popular, but are not polarized and will happily connect red to black if you make a mistake. There is a standard Powerpole arrangement, e.g.

but this can't completely prevent human error. One major transceiver manufacturer deliberately installs Powerpoles in reverse of the standard arrangement, to influence buyers to use their supplied power cable.
I found an article on how you can prevent reverse polarity damage by adding circuit component(s). Both simple and not-so-simple designs are given. The article was written by John KC9ON who also has a small online store: 3rd Planet Solar/KC9ON, https://kc9on.com/
I attached his article. Good reading.
