In my caravan I currently have an option to switch of my 12 volt battery. I also have a Victron Phoenix 350/12 inverter which has remote on/off functionality. I would like to make use of my existing outlet to be able to switch the inverter on/off remotely from within hand reach, while currently one switch in the outlet is not used. Could I do the setup as in the picture? Thus combine the 12 volt and 5 volt (neutral) wire?
Hope you can help.
