I do it all the time, in the process of powering HF/SSB radios onboard.
It's important to bring the main power from the house batteries up to near the radio
. I use AWG6 or AWG4 cables
, with fuses
located near the battery
bank, up to a small 2-position terminal strip near the radio
. The terminal strip looks like this: 2 Circuit - PN 2402 - Blue Sea Systems
The large cables
from the battery
connect to the terminal strip with properly crimped ring terminals, which I cover with adhesive
heat shrink tubing. The ring terminals have #10 holes in them to fit the terminal strip screws. Sometimes the terminals are too wide, and it's necessary to file them a bit so they fit properly.
Then, I bring the short power cord from the radio to the terminal strip. Usually it's AWG10 wire. I use adhesive
heat shrink ring terminals on these, again with #10 holes to fit the terminal strip.
Simple. And, it makes a very good connection which can be opened and inspected as required.
