Although I've featured Wago terminals and their clones in the past, I've never really explored the internal mechanism in detail.

I have now.  And the clone was actually surprisingly good.

Reassembling the clone was easy, but the Wago did not go together again, as it has lots of loose and very stiff spring contacts that all need hooked under a common strip simultaneously.

Inside a Wago connector and a clone

Wago terminals are here to stay. They have a long history, make easy, good connections and avoid issues with over or under tightened terminal screws. They are fast and easy to use, and there are dedicated purpose junction boxes designed specifically for them. In this video I took a real Wago connector apart and a generic clone in fetching pink. I gave up on trying to put the Wago connector back together again. It clearly requires some sort of factory jig to clamp the springs in position as the contacts are inserted into the housing. The clone was a different story. It went back together easily with a very refined approach and single spring strip. Both connectors have tinned copper busbar plates that the wires are clamped against by spring steel grips. It's inevitable that roque products will creep onto the market at some point with lower quality contacts, so for safety reasons for professional electrical work I recommend only using genuine Wago terminals bought from a local high profile supplier. For personal technical projects the generic imports may be a useful alternative.

Alas poor Wago, I knew him well. Send in the clones! Where are the clones? Nevermind, they're here.

I have started using Wagos here in Texas. I find them easier to use than wire nuts and less likely to cause a wire failure, especially if the box is crowded. I have used clones on bench projects too and have had good luck with them.

Wagos are cleared with local inspectors? I'd hate to invest in a bunch of them to rewire a house and have it fail because the inspector doesn't believe the kitty bitty pieces of Lego can work as well as a tried and true wire nut.

I would check your local codes but electricians are using them here in Houston. The only resistance might be that they cost a tad more.

Wire nuts were banned in the UK decades ago. They had a reputation for cracking. John Ward did a video where he overloaded a Wago until it melted. IIRC it needed triple-digit amps for some minutes.

American here - I discovered Wago connectors a year or two ago and I'll never go back to wire nuts again!

I bought some Chinesium copies off Amazon last July (I got conned by the Advert which said 100 pcs for £9.99- they've altered it a bit so you can see the real cost/ unit now) But.. they are not bad, they seem very robust, hold the wire well and have been in use ever since without a problem. Here is the link so you can judge for yourself : https://www.amazon.co.uk/gp/product/B091FLD6LV/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

Quicker to wire as even the lever version you can just push the normal single stranded wires in. I know the wire nuts are quick but still Wago faster.

Even the wiring regulations favor the wago as if you use screw blocks you need regular inspection as the screws can work loose! I have seen wago cut wires which have mechanical movement so always provide strain relief. If you look at the wago boxes they have strain relief and to cover yourself on the regulations to not to inspect the connection regularly you have to use connections in a wago box!!!

That WAGO mechanism looks like a cam type of lever. They both kind of have a cam lever style, don't ya think?

Do the clones have test points like the Wagos?
