Splicing 6+ Wires

Question

My project contains a 12V parallel circuit and multiple switches. What is the preferred way to splice 6+ 12AWG wires together. My first thought was using butt connectors with 3 on each side, but at 12AWG not sure I'll have enough room with standard connectors.

Is there a Wago connector that suits your requirements? – Andrew Morton May 20 '21 at 21:28 — Andrew Morton, May 20 '21 at 21:28

When I was wiring up +12V & GND wiring for some low voltage circuits I used connectors like these with very good results.

These work well with either solid or stranded conductors in a range of sizes from 24 AWG to 12 AWG. They are rated for circuits up to 20A.

These come in sizes of 2, 3, and 5 common connections. If you need more than 5 connections you just have to jumper two connectors together with a short wire. With two 5 position units jumpered together you would achieve ability to connect 8 additional wires together.

Just be careful with the levers. They snap down with a surprising amount of force, and it can sting! – Hearth May 21 '21 at 03:26
Never had the hard snap experience but maybe with 12 awh solid wire. – Michael Karas May 21 '21 at 04:06
@Hearth The new design (as shown in the image) is much easier on the finger tips, in my limited experience. – Andrew Morton May 21 '21 at 22:52
The new design parts as pictured are the ones I have used and the levers operate with ease. – Michael Karas May 21 '21 at 23:06

Butt connectors can work but you just need to make sure that you match your wires' combined cross-sectional area to the connector. We have a circuit that requires 12 16AWG power and 12 16AWG ground connections to be spliced together and connected to a single 6AWG wire for each branch. We use 6AWG butt connectors that are sized appropriately. For 6 12AWG wires, you're in 4AWG territory so the crimper might be prohibitively priced.
