I have watched the Lionel's (Mike Reagan) Video on buss wiring several times. The assumptions I have made are:
The Buss wire(s) is a Red wire and a Black wire at least 16 gauge. The red wire is connected to the middle rail and the black wire to the outside rail. The addition loops are connected via a red wire jumper from the track to the red buss wire.
The Black and red wires are connected to the power source (my case a Lionel 180 brick).
If you have more than one loop, the black wire needs only to be connected to one loop but can be connected to all if desired.
What do you do with the other ends of the buss wire(s)? Per the video, you leave them unconnected to anything. Do you need to have a cap of some sort on the bare ends?
Thanks
