Today I started running the wires between the breakers and the switches. For marking I am just using yellow shrink-tube and an industrial sharpie. We will see how it holds up over time.
After running quite a few wires I realized that using the bottom of the panel wasn't going to work as well as I would like. I decided to add a separate support for the wires. Using some J-stringer I had laying around I made a dedicated run for the wires. I will pretty up the wiring once I have all thr wires routed.
