I am installing the radio in my ASII project. The original builder had, what I consider, an incorrect supply circuit. This is the second time I have seen this. I rebuilt a Kitfox that had supply from the power buss to each switch, then to a breaker, and then to a component, radio, lights, etc. Now, wiring in my ASII radio the original builder installed power form the buss to an "Avionics" switch, then to a sub buss, and then to Klixon breakers for each avionics component. The breakers were also being used as switches for those avionics components.
My question is why would someone, actually 2 out of 3 of the planes I have rebuilt, chose to add the breakers after the power switch? It doesn't make sense to me to leave the switches and, now with the ASII, a sub power buss, unprotected.
Am I missing something with aviation electrical circuitry fundamentals. The quality level of everything else in both the Kitfox and this ASII project is exceptionally high.
