Main Bus Wiring - Thread from Digitrax List


Blair
 

Hello, All

This came up on the Digitrax list.  I thought this might be of interest, and certainly more on-topic, here.  For those who don't wish to solder every connection on the layout, it's often necessary to choose a connector, or connector system.  Recently, I've become aware of the "lever-nut" connector systems.  I believe they were pioneered by Wago, but there's lots of options out there now.  Here's a few, from AliExpress.

The following are links to AliExpress web pages; sometimes, you have to select a product variant to see exactly what I'm referring to. You may have to cut and paste carefully into your browser.

This one looks even better - one in one out, four taps:

They also have these products, which solve the tap problem for two-wire busses simultaneously; best I could find was two in, two out, plus two taps each:

(at that link, select colour option VSE2-4 or VSE2-6)

And, here's a very nice option which includes mounting ears:

And choose colour "MULTI" - it was fourth option from the left.  I have no idea how hard it is for you to access these products in the USA.

These products have specifications that I think are "optimistic", but since they rate them at 32A 250VAC, I figure my 3A booster runs at 15Vpp should be okay.

Usually, different handle colours denote separate circuits, so I would expect, for example, colour 2-2 would be a simple inline splice for 2 bus wires, whereas six orange handles, whether arranged in 2 sets of 3, or one set of 6, would be all one circuit.
