You do not need to run dedicated wires since the TT is already wired for 12vdc. The Converter is actually a Large 12vdc power supply, it will convert 120 ac to 12 vdc when you are plugged into shore power or running a generator. It also may have a 12 vdc battery charger as part of it. In the case of my TT, I just flip the circuit breaker off since the Solar Charger keeps my batteries topped off, and in the evening I have enough Battery to operate the TT. In my case if boondocking, I will still need propane to operate the refrigerator, forget about AC’s unless I want to operate the generator. However we are good with TV, hot showers, a little bit of microwave etc.
