Wiring Layout So It Can Be Disassembled...?
« on: June 05, 2016, 09:52:32 PM »

I've been planning my future layout so it can be disassembled and moved if necessary. For example, I will have a 10' x 30" shelf that I want to be in 5' x 30" sections. Of course, I got to thinking about making the wiring underneath sectional too. Would it be some sort of crime to make my 14 gauge bus wires under the shelf, for example, into two 5' sections joined by terminal strips every 5' so I can unscrew them if I need to move the layout?

I originally planned to have the layout electrified by 50' of continuous bus wire. Then someone suggested I make the bus 25' long, connecting to power supply via terminal strip then another 25' of bus wire connected to the same terminal strip.

Sorry I'm so ignorant.


Hmm... that's okay, Kiz.
We're used to it...


Two scientists create a teleportation ray, and they try it out on a cricket. They put the cricket on one of the two teleportation pads in the room, and they turn the ray on.
The cricket jumps across the room onto the other pad.
"It works! It works!"

Every wire joint at a terminal strip introduces a tiny bit of resistance and also becomes an additional point of possible failure.  But if you are careful, that should not be a problem.  After all, there are some large NTRAK module layouts aou there which use DCC and have connectors on the bus every 4 feet.

Maybe before you plan your electrical bus installation you might want to post a rough diagram of your layout to get opinions on how to best approach the wiring of the layout's sections.

I'm also confused on the size. It will be a shelf layout which is 10 feet deep and 30 feet long. divided into two 5 x 30 feet sections?  That's huge for movable sections!

@peteski he said 5 feet by 30"

Science isn't about why, it's about why not. Why is so much of our science dangerous? Why not marry safe science if you love it so much? In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired! Not you, test subject, you're doing fine.

If you're simply planning for the eventuality that the layout might be moved. Why not just add a little slack to the wiring, then if the move happens you can snip the wires at the section joints and add in connectors or Terminal Strips or simply rejoin the wires with a lineman's splice, solder it and cover the joint with shrink tubing.

Or instead of terminal strips, use Molex multi-pin connectors in however many pins you need to connect wiring across sections.

Our N-Trak layout has a large yard that has 12 tracks and spans three 6' modules.  To supply power to all the yard tracks on each module, we used two sets of 12-pin molex connectors for each section, plus similar connectors to connect the yard control panel to the center module.  This yard is now about 20 years old, and we've never had an electrical failure, even though it gets stored between shows in an enclosed trailer parked in a cornfield with outdoor temps that range from 100 in the summer to zero (or below) in the winter.   Using Molex connectors takes some planning and soldering (you have to solder the wires to the pins, then insert them into the connector in the right order to match the male to the female connectors), but they have proven foolproof in our club environment, which is hardly ideal.

I had the same design challenge when I started working on the Windsor St layout.

I ended up going with terminal strips, but only where they made sense block wise. Because it's all screws, when it needs to move, I can just unscrew them.

But, at the same time, I wouldn't go overboard and waste time, money and effort adding extra terminal blocks or plugs (even though Molex or Power Poles would do the job) for what would be a one time event. Just include some extra slack in the wires like Ryan suggests and cross that bridge when you come to it.

Yes, Ryan makes an excellent point. If the possibility of the move is not a certain, there really is no need for adding connectors or terminals now. Just leave some slack on the wires where the bench-work sections meet, and if they end up being moved you can then cut the wires and then reconnect them after the move (using one of many available methods).

I have been using Anderson Powerpole connectors for my DCC and Accessory buses.

You can get them in different colors, and you can stack them to effectively make a 2 or 4 or whatever position connector.  The stacking options also let you build a keying system into your connections.

I just bought some of these from home depot and there awesome I'm using them for a 12 v. lighting buss.
Just strip,insert and connect, very fast. they only go in one way so there stupid proof.
  i found link cause it's faster than taking a picture.

The electrical bus only has one "s" (just like the road vehicle).  "Buss" is a brand of electric fuses from Copper industries (or a kiss), or simply a typo. . .  :D
