I'm confused regarding the wiring of my layout.
I'm using an EcoS and Traincontroller with my layout and I'm asking for opinions as to which wire to use. Firstly, the wire from the EcoS to the layout. I was suggested to use 0.75mm stranded copper wire from the EcoS to a central point where I can distribute the power to different parts of the layout. Again, from the central point to the layout, I'm using the same wire.
Secondly, I'm connecting to the C Track to an s88 unit for occupancy detection, and the wire I'm using here is 0.5mm stranded copper wire.
Is this wire suitable or is there better wire to use?
Another question on wire - is it better to use thicker wire if in doubt as this gives better conductivity than a thinner wire?
Regards

Take it easy . . . . or any other way you can get it !!!!

Greg The thicker the wire, the less voltage drop you get over longer distances due to the thinner wire having a higher resistance. This makes it necessary to have a thick enough cable for your bus and enough feeder tracks so that the trains gets the required voltage to operate (particularly in the case on compact c-sine which were rather voltage sensitive prior to the SDS update) I am using 0.5mm solid core for my S88 detection, they are short runs and won't be a problem so I wouldn't worry. I am using 16 gauge for my bus cabling, which is overkill, but its cheap and easy - figure 8 audio cable is perfect and readily available. |

Hi! Originally Posted by: Drongo Another question on wire - is it better to use thicker wire if in doubt as this gives better conductivity than a thinner wire? Yes. The voltage drop grows proportionally with the current and the length. You reduce the voltage drop by half if you double the diameter of the wires. So there is no "One size fits all". A small Xmas tree layout with just one loco has a low current and short distances and thin cables will do. And don't forget the "²". You probably ask about 0.75 mm². 0.75 mm² should be sufficient - even for the 6 A of the new ECoS 2.1. For very large layouts with very long cables, thicker cables may be required to keep the overload detection operational. |

Yes, the "squared" was missing from my message as I didn't know how to do it from the keyboard - perhaps another question (and off topic). Again, thanks for the help. Regards Greg |
