Next step is to make a removable panel for the circuit breakers. I made a list of all the breakers I needed and figured out the optimum spacing, both horizontal and vertical, so they would fit inside the real estate I had available on the panel. I made a scale drawing on graph paper, then made a template out of a manila file folder. I also tried to group them by function. For example the bottom row is only the avionics and will be powered through the avionics relay I bought through Steinair.
