Electricans, I still run DC on my layout. I see handheld throttles that seem to use telephone cable to connect to the layout. I use two handheld throttles I built years ago from schematics. One is a small DC throttle with about 13 volts input and the other is a SCR throttle with about 24 volts input (12v. output). I run only one engine per throttle. I would like to have plugin connectors on the other side of the layout so I can follow the trains better. Is telephone cable big enough to carry the current to and from the throttles and use as a connector or do I need something bigger? Thanks for any help you offer.
