While I chose not to (over) design my layout, there are some aspects that simply have to have a structured and logical approach to simplify troubleshooting for the longer term. These need to be in place to allow me to add to and grow the layout in the future. This post focuses on the wiring standard for all layouts that I build going forward.
After watching the current work being done over at Everard Junction with the wiring of the new section of his layout (+ Link) one of the things I noticed was the colour code in use. I feel that in the future he’ll find that there’ll be more stress and confusion in the future when tracing and troubleshooting.
As a former telephone technician colour codes are very important to me. As a result I’ve written a module / baseboard wiring standard. If you are not worried about troubleshooting your wiring in the future you can ignore this post now. Each module / baseboard will have a dual wiring BUS. One BUS will power the Locomotives and DCC accessories (the DCC BUS) while the other will power the DC accessories and other non-DCC devices (the DC BUS).
You might be wondering why I’d have non DCC accessories. Think for a moment of LED lighting. LED Lighting is 12V DC so lighting the module / baseboard is made easier using the 12 volt BUS. Additionally internal building lights, signalling and repeater panel lights that do not use DCC to operate can be powered off this BUS. Finally there is no extra effort required to wire these up later; its wired into the module / baseboard from the get-go. There’s no extra work to get DC powered items wired up beyond setting up dropper wires to the DC BUS.
There’s a download!
The wiring standard for the boards and modules is a work in progress. You are welcome to download version 1. Please keep in mind it is not in the public domain. You may use it for personal use only. Any commercial applications of the document should be run by me first.
I don’t claim that this is the standard your should be using; it works for me and that’s all I care about.
