When I re-wired my rig for lithium power in the passthrough, I did not feel comfortable having an unprotected circuit inside the rig to the break away switch. On the TT in its original configuration, the break away is wired directly to the battery outside the rig. I inquired for the acceptable method and found that a direct connection has to be made but a breaker can be used on this circuit as long as no other components are connected to that circuit.
My break away is also wired through the main switch where I struggled with this initially. I was considering a frame mounted break away kit with aux battery and charger where the charger function could be protected via a breaker. I finally just left the break away switch configured through the main switch at the docking station and protected that circuit with a dedicated breaker. We travel with the fridge on and also need the switch on to operate the tongue jack so there is no possible way to forget to close the switch for the break away function during travel. My main switch was also replaced with a Sierra marine switch with a much stronger detent to be sure it stays closed during travel. This configuration is a compromise but one I am comfortable with.
