Windjabbers Posted May 19, 2020 Share Posted May 19, 2020 Sorry, really basic question here, I need to join 8 wires to one on a common return in to a CDU Capacitor Discharge Unit. What's the name of the 'thing' that I can uses to do this. Can't search for something when I don't know what its called, if you see what I mean!

Crosland Posted May 19, 2020 Share Posted May 19, 2020 Soldering iron. Henley block (all terminals are common). Screw terminal block (fit one or two returns per terminal and run a common wire between each terminal). Crimps of various sorts. 1 1 Link to post Share on other sites More sharing options...
RMweb Gold sjp23480 Posted May 19, 2020 RMweb Gold Share Posted May 19, 2020 or you can use an earth terminal block, pretty cheap from Screwfix or similar: 1 1 3 Link to post Share on other sites More sharing options...
Windjabbers Posted May 19, 2020 Author Share Posted May 19, 2020 Thanks for the quick replies - now I know what these things are called I can have a look at the. Am thinking that the earth terminal blocks is all I need. Best Wishes David Link to post Share on other sites More sharing options...

Thanks David I've moved to Wago connectors - see Ebay for plenty of choices. You need either the 221 or 222 version. They're cheap and you can connect wires to them without soldering or using a screwdriver - big advantage if you're working under the baseboard. If the wires are all of the same gauge, you can put two wires into each slot, so a 5-way would be fine for 8 wires. I use double-sided sticky tabs to fix to underside of the baseboard.

cliff park Posted May 19, 2020 Share Posted May 19, 2020 The best thing about screw terminals is the ability to remove (or add) individual wires. You may think that's unnecessary, but sod's law says you will, one day. 1 5 Link to post Share on other sites More sharing options...

RMweb Gold RFS Posted May 19, 2020 RMweb Gold Share Posted May 19, 2020 Further to my post regarding Wago connectors. I simply bought a box of 60 for use around the layout. A set like this can be had for just under £10 from a variety of Ebay sellers. They also show up on an Ebay search for "wire nuts" for perhaps they're the latest incarnation .... 1 Link to post Share on other sites More sharing options...
RMweb Gold ITG Posted May 19, 2020 RMweb Gold Share Posted May 19, 2020 I too like the Wago connectors, but also these on amazon, with ready made slot-in links for combining several https://www.amazon.co.uk/JJDD-Position-Pre-Insulated-Industrial-Instrumentation/dp/B07S3L9KVQ/ref=sr_1_2?crid=2PV0X7GMKFY4T&dchild=1&keywords=jjdd&qid=1589899070&s=diy&sprefix=Jjdd%2Cdiy%2C146&sr=1-2 1 Link to post Share on other sites More sharing options...
WIMorrison Posted May 19, 2020 Share Posted May 19, 2020 @itg Those are for connecting terminal strips not for connecting WAGO connectors (which I must admit have never heard of being referred to as Wire Nuts) 1 Link to post Share on other sites More sharing options...

The first time I tried to change a light fitting over here I looked at the wire nuts provided and wondered where the screw terminal connectors had got to Last time I swapped out an old fluorescent light fixture I binned the wire nuts and used two way Wago connectors instead.

RMweb Gold ITG Posted May 19, 2020 RMweb Gold Share Posted May 19, 2020 WIM, yes, I don’t use the two types of connectors (Wago and terminal strips) together. Just two different options for different circumstances. 1 Link to post Share on other sites More sharing options...

Tricky Dicky Posted May 20, 2020 Share Posted May 20, 2020 (edited) +1 for Wago connectors, they are far superior to Scotch Lok which are often recommended for quick screwless connections. Wagos will happily connect a wide range of wire from 4mm sq. down to 7/0.2. I can attest to the latter having tested to destruction, I pulled the wire apart before the Wago let go. Do go for the the genuine ones as there are a lot of clones on the market and their properties could be suspect.

WIMorrison Posted May 20, 2020 Share Posted May 20, 2020 ScotchLok and Wago connectors have very different use cases and are not replacements for each other. 2 Link to post Share on other sites More sharing options...

Please explain how? You can make exactly the same kind of connection with the appropriate Wago as you can with a ScotchLok with the advantage that a Wago can cope with a greater range of wire sizes. The only circumstance I can see a ScotchLok would be better was if your wiring was strung out like guitar strings. Richard Link to post Share on other sites More sharing options...
WIMorrison Posted May 20, 2020 Share Posted May 20, 2020 ScotchLoks are IDCs for splicing into wires without breaking the wire, whereas with Wago need you to split the wire which you cannot do in a loom or cable bundle. They are complementary to each other, not subsidies for each other 1 Link to post Share on other sites More sharing options...

I think Scothlok got a bad reputation through being used by "grease monkeys" on car electrical systems. They work well when used correctly, i.e., correct sized connector matched to the wire.
