Re: Jmri interface
Not sure what you mean by interface wire.
There are 3 classes or wires found in a layout.
1) Low Voltage Control/Communication Cables
2) Low voltage DCC Track or DC/AC cables that distribute layout power.
3) High Voltage 120V/220V AC power cables.
In general it is bad to mix Class 1 with Class 2. There is no hazardous power involved. The only problem with mixing them is noise and communication problems.
You can bundle Class 1 cables in a loose group of its own and you can bundle Class 2 cable in a loose group of its own..
You cannot bundle a Class 3 cable with Class 2 or a Class 3. When it comes to high voltage AC outlet power, I would not wrap it that cable with anything else. The AC cable is a hazardous cable and should be protected from accidental contact with tools or anything else that one might use in wiring up a layout. It should be run all by itself away from all other cables and given some mechanical protection thoughts as to its installation.
