The Model Rail Power Bus bar Kit includes a 10m length of Black 32/0.2mm cable, 10 cable tidy clips, & 10 quick connect clips.
The cable is capable of carrying 10 Amps. The Bus bar wiring is designed to provide the maximum amount of current to a specific point in the track, so the more spurs you have the less likely you are to get voltage drop. The wires (Positive & Negative) can be twisted together to reduce the amount of interference you get, some people think this does not work, so try it out. The ideal solution is to have a 'ring main' so the far end comes back and is joined to themselves as close to the power source as possible.
