I've fabricated a copper bus bar to feed 12 volts to all of my toggle switches on the right side of the IP. This accomplishes two things. 1) Reduced wire count - I only need to run one 12 volt wire from my master bus to the toggle switch bus. 2) Additional strength for the toggle switches - since they now have an anchor at both the front and back of the switch. You can see that I have expansion capability of two more toggle switches if needed in the future. You can also see the hole I have prepared to accept the 12 volt feed wire. Well, I just realized that my bus bar idea will not work with the fuse block that I purchased. Too bad - I really liked the idea.
