Thanks for options info.
How about using your last feeder connection along the buss line ?
Would it be okay to " dead end " the wire inside the IDC connector.
Just cut the wires off and hold them mechanically in place....Really,the electrons won't escape. :-)
Adding a wire nut to each wire will help ensure that nothing elsetouches it. It could also end at a terminal strip for future expansion
of your empire.
Better yet, the end of the bus run is the ideal place to add an R/Cbus terminator. So put ae point terminal strip there and use the
center terminal for the R & C tiepoint.
