Look at your own diagram, three wires running parallel to each other fro several metres. There is capacity between them. One wire is permanently connected to Live 230 volts AC. Therefore the other wires will have 230 volts induced onto them.Thats obvious but both ends are floating in thin air, voltage has been induced on line, no capacitance theory in my mind!
dont wanna argue over the matter, people trying to show how clever they are/or not!
Not trying to be clever. just offering knowledge gained from 40 years working in electronic design to help you.
