Before I fabricate my own, does anyone know where mini, model boat sized bus bars ready made might be available?

I give up, what's a bus bars?

It looks like this:



It is for attaching circuits.

In France Legrand make a push in connector for house wiring junctions. Available in several sizes and for joining 3 or 5 wires. If the wire is not rigid it should be soldered to enable it to be pushed in. Connectors work well - and disconnect when you want. Very compact, as long as you don't want a fixed set of terminals as in your photo.

Possibly something similar from car accessory shops, but those I've seen are a one way trip.

Radio Shack doesn't have something like this?

Flabum: that is a terminal strip. Terminal blocks are the same. I have those. I need a bus bar. But thanks!

Tug Guy: rat shack does not show anything on their website. They have basically dropped out of the electronic parts market anyway.

expat: I will check out Legrand. Thanks for the lead.

Kmot,
Try Hosfelt.com They have barrier blocks that work very well. I have used them in various sizes and use crimp ring connectors to fasten the wires to the contacts on the blocks.

Kmot,
there are jumpers to make a continous bar for as many contacts as desired

Kmot I totally don't understand how these are used in a model boat. Would you enlighten someone less knowledgeable? I thought a terminal strip was the same thing?

go to an ele ctrical shop and buy units that are fitted in consumer units and joint boxes .
nb,, a busdar is a connection like a flat bar made of copper or silver that has vorios drilled holes in it of 2 or more sizes as insulation use apiece of non conductive material .rigid plastic etc .

He is looking for something that is sub-miniature which is hard to find. I have not found anything like what he wants on the web, the part I posted is small and I figured he could just solder a piece of wire across the terminals, but obviously, he wants something more professional looking. All the bus bars I have found use # 8 or bigger screws, bet he wants something with # 4 screws. It can easily be made with a length of eigth inch brass bar fom the hobby shop and a small tap.

Perhaps he is wiring lights?

Okay fella's, I had to make my own. Spent the afternoon doing it which I would rather have worked on something else.

I initially purchased Terminal Strips/Blocks and nearly had hooked it up to my equipment before it dawned on me what a disaster that would have been! I realized, fortunately, that what I needed was bus bars and so did not apply power and fry my electronics! [X(]

The reason I am using a bus bar is so I can power it up with the battery and then plug the various electronics into it. That makes it easy to remove electronics when necessary. Attached pictures show the bus bars. I made them from oak wood, aluminum sheet, stainless steel screws, and plain steel nuts. I had to meaure, cut, drill, radius, sand, etc. So now you know why I wanted some store bought versions.

In the pics you can see my electronics as they will be layed out in the boat. The open connectors shown, will be connected to a battery source and the JJC sound module.

Thanks for all the leads!

I know I am dense but I still don't understand the difference between a bus bar and a terminal strip.

Tug

Flabum

wow, that looks like a busy boat.....what is it?

Flabum

come to think of it, I thought you wanted something smaller. West Marine has a brass one with #10 screws similar to the size you built. The one you built looks superb.....very professional.

West Marine? Is that r/c boats or full size?

This is a Midwest USCG 47' Lifeboat.

Wow!! Those would have been perfect!! [X(]

I saved it in my bookmarks. Thanks!

Tug Guy.

Terminal strips will do the same thing. with 1 side using jumpers going in and out of each terminal.

The Euro type strips have complete plastic insulation over all the metal terminal parts to prevent shorts.

2 strips are normally used. There are also fused terminal strips.

It comes down to what your eyes like better.

cyclops2, please show me how you can use jumpers on the terminal strip in the photo above.

Tug Guy

Thank you for keeping from thinking I was going crazy. Your description is how I used them on a very large Puffer. It confused me as how the bus bar was any different from the terminal strip with jumpers. I am too old to be confused this badly.

I'm having trouble visualizing this. Could someone show a drawing or post a pic?

Tug Guy

Kmot maybe this will help. Look for the 8 position jumper. There is also a 5 position jumper.
