DCC Wiring question

Robert Bryce

Question:  DCC wiring.  Can I bundle wires 1  2  3  and  4 into the same wire run as long as they are all twisted.

If you are asking about the wiring of occupancy detection sections, the answer depends on the length of the run. It is better to place the detectors out by the track sections being detected to minimize possible capacitance of twisted wiring pairs or other pick-up interference that might cause an empty track section to be falsely claimed as being occupied. If distances are relatively short, say less than 10 feet,the chance of interference is rather small. So yes... you can run multiple feeders of twisted wiring pairs along the same path with minimum interference.
