My students we just today complaining about the access to wires on the panel mount breakers. The lug idea with separators might be a fix. It definitely needs to be done differently. In class We added another inverter to our package and trying to install another 175A breaker was a pain. We have a few other DC breakers in there already. The whole cabinet is basically inaccessible.
