It really depends on your definition of "Chinese manufacturing". Sometimes it's just a subcontractor making product for a different company with high standards. It could even be a Chinese division of a company like WAGO. Or it could be a company competing only on the lowest price, which might take a ton of shortcuts to meet that lowest price. Or possibly a Chinese company that tries to meet high standards. There's been a certain amount of ridicule of "Chinesium" or products that seem to be based on the absolutely cheapest manufacturing and support. I think we've seen some of that her with parts that aren't finished nicely. The (likely) solid copper bus bars aren't anything like the tinned copper bus bars that WAGO or Ideal use. You can look through a lot of the ad copy or instructions and see various amounts of spelling and/or grammatical errors in English. They might slap on a CE label, which only means the manufacturer claims that it meets European safety standards.

The multi way ones are useful in lighting circuits and industrial control applications....but I would only purchase them from an electrical wholesalers for the exact reasons Mr Ward describes

Yeah, I got some for quick hobby project use, too. Usually 3 or 5 volts and temporary patching together. Usually 3 individual wires to 3 individual wires or 2 to 2. Sometimes in place of alligator clips, that sort of thing. I've found them very useful. Never used them for line voltage or permanent installations.

Red blue is a common standard for line/neutral in France and several other countries China seems to use yellow/green/red for phase black/blue for neutral and greenyellow for CPC

And we will all find a use to connect two pairs of wires, 3 wires and even 4 wires together 5:28 I don't know what planet JW lives in to not find any application for a wire-joining terminal block/strip DOH.

@@johncoops6897 I think JW still twists wires together then tapes up with insulation tape!

It’s a liability issue if you are a professional. I wouldn’t hesitate to use them myself but I understand JW’s position.

You do not think from an engineering point of view. Items size,shape,materials, are all calculated and is for a reason.China isnt on the same page with really anything but making money let alone our electrical codes.

I wouldn't use them on a customer's property and would not use them on my own therefore. It is my sincere belief that China deviates from material integrity with the purpose of undermining every society in their quest for dominance. I don't trust anything out of China. ( From 40 years experience in the building industry )

I disagree. Wire nuts can be horrible, but if they are good quality and the right type, they can be very good. In my experience, a properly made splice with a wire nut is more reliable than a Wago lever nut. The only problem is that in order to use a wire nut, you have to twist the wires together first, which can break old wiring that has become brittle. I use Wago connectors for temporary connections, old wires (to avoid breaking), and situations where it is difficult to use a wire nut. Wago connectors have the advantage of being easier to connect and disconnect, but wire nuts, if used properly, are more reliable.

@@skyem5250 These old hands are beginning to struggle with wire nuts when there are more than two wires; I use them for #12 and bigger wire. Where I really enjoy the Wagos is in installing Shelly, Sonoff, and other IOT devices in boxes. But I limit those to 2 or 3 amps max, so #16 or 18 is even possible.

@@johncrunk8038 I don't trust cheap IoT devices, so I wouldn't want to have them installed in such a way that I can't easily unplug them if something goes wrong. Also, if you have a 20A circuit using 12AWG wire, you have to use 12 throughout. The only time I can think of where you can splice different gauge wires is if one is permanently attached to a device (for example, a dimmer with 16AWG wires). I'm 90% sure that's an NEC rule, but sometimes NYS adds additional rules. Also, in addition to being of questionable quality, almost none of those cheap IoT devices are compliant. They make tools specially for twisting wires and putting a wire nut on. I don't know how good they are, but you may want to do some research about those if you do a lot of electrical work.

@@skyem5250 Dude. Wire nuts suck. Imagine having to turn off power everytime you need to change an existing connection.

SCWfan06 you think we turn off power here all the time ha ha ha ha ha ha

I like it when he said "you don't want to get blamed for it" with a stoic face. I was laughing hard.

The current test would be nice. I think these might be suitable for mobile home 12VDC installations, as the spring contact seems to be sturdy. Would the Author of the channel like to give a comment on that kind of use?

@@eelipiirola5132 I came to this video from another video where he did test the current. not much different from a wirenut. they are all made from plastic and bits of metal.

He has another video for that. The Made in China burned first.

Sure, but at that current both connectors were destroyed (~5 or 6 times the rated current). I'd call them equivalent based on that test. I'd only definitively call one better than the other if that test were repeated a number of times and gave a consistent result one way or the other.

Wagos suck ass! Lol

@@appleejack That wasn't my question...

Really, stupid video. If you are gonna criticise a product you should point out the fault. Just because they are made in china doesn’t necessarily mean they are bad. Although, most of electrical items are indeed made in china. Next time you test something get the original ones too and then come to the right conclusion. Not just your opinion because opinions are like a...... we all have one. Thanks

@@mixologist4hire Well i wouldn't put it that strongly. I simply suggested a comparison with the Wago's - where they are made didn't enter into my argument! Lots of factories produce top quality and "ecomony quality" on the same line.

Peter Jones I appreciate the fact that you have taken your time doing this video and in my experience using wagos and so called wago clones I can only see little difference between them apart from price. To compare something you need to have both items then you can give a professional opinion on the findings. Thank you anyway!

I'm a year late to the party but I have an observation. The genuine Wagos are approved for use in the US, Canada, and the UK, as opposed to the Chinese knockoffs that aren't. The knock offs are CQC approved; Chinese Quality Control. I use Wago all the time. I love them.

Got another one for you! Chinglish, it's what the instructions are written in, 🤣

if your dealing with soviet made stuff stalinium may also be a good piece of vocabulary

Check out AvE over on the Boltr channel. He's the guy that has us all saying it.

Away from the comparative safety of standards and regulations you find twin and earth cable in all kinds of colours and worse still the conductors are steel flash coated with copper! So yes that copper looking conductor might not be what it appears to be - chinesium as JW would say!

Not really any use for home audio / speakers because you don't need to terminate those. The audio device already has output terminals and the speakers already have input terminals....

I only ever use them in low voltage, low current applications with a 10 or 20 amp fuse protecting them.

They're probably just as fine in higher current. The problem is not actually quality but liability or here lack of.

So I have discovered recently while working on some rather poor imported machinery. Spent nearly $5000NZD putting right some of the more obvious errors and omissions. And there will be more yet. Not the smartest purchase that customer has made. The welding of the steel has to be seen to be believed.

@@johnsimpson8263 In my opinion it is not very smart to use green as a colour for a line conductor. Could be confused with the green/yellow striped for the PE. The european colour code is designed that way that even colour blind people can distinguish between the different colours: -L1: brown -L2: black -L3: gray -N: blue -PE: green/yellow striped

@Indosarnia - they are certainly too dangerous for people who cannot spell properly.

I think Wago make a box specifically for moving a consumer unit

I'd leave it to the professionals! You obviously don't know what you're doing

As far as I'm aware there have been no recorded failures of genuine wago connectors as long as they have been installed correctly

The problem is the strength required to open the levers.

Springs are steel, the other strip isn't attracted to a magnet so could be copper, or plated copper for the silver coloured one.

@@jwflame Thank you, interesting to calculate cross section of the conductive part, what do think. Looking forward to smoke and burn episode 👿.

@@jwflame I'd be worried about corrosion resistance. The springs *could* be cold-formed stainless steel (which becomes attracted to magnets after cold working) but probably aren't. The conducting strip *could* be copper but could be something prone to corrosion with a very thin plating of copper that is porous. They *could* be fine. But if they'd been designed conscientiously they'd have had sensible colour codes on the levers. So probably whatever crap they could get away with. Which means eventually the springs will corrode until they snap, or the copper plating will lift off. Then again, if they're Chinese Wire Connectors maybe they work really well with Chinese Wire. That thin, shoddy, copper-plated non-stainless steel crap. It's possible. But unlikely.

@@bdf2718 my guess is that the main conductor is Copper plated Aluminium like most Chinese wire seems to be these days

@Indosarnia - I find myself cringing at his naivety.

You're right Phil, WAGO do have manufacturing plants in China. These are most likely either reverse engineered, or simply from the same factory. The springs are strong, they grip the cable well. The contacts are copper. The insulation resists over 15 times the rated voltage. I couldn't understand the issue with the colour of the levers - I thought it was to show that they're wired straight through more than anything else, especially as no two countries seem to have the same colour coding anyway. They don't look too bad to me...

JW sees absolutely no need for connectors that can join two wires together. 5:28 I have no idea what else you'd use wire connectors for, but he thinks he's the expert so that's that.

It said "4KV" on these ones, did your 1 kV failed ones have any sort of separation rating shown on them?

No, but the new 2 holes ones are so small (2273-202), there wouldn't be much point anyway.

Extending a ring as-in Goatse ???

Wire nuts are theoretically suitable for use. However no electrician in the UK will use such things, as they are inferior to pretty much every other type of connector. The main problem with wire nuts is that they twist and mangle the ends of the wires, which makes subsequent alterations, additions and testing far more difficult.

@@jwflame Nonsense. Ideal wing nuts are far superior to these wagos. They are industrial strength compared to quick and easy. You can hang from an ideal connector.

The other good thing is that the Chinese will print any brand you want on there. So, if you want "Wago" written on there, no problemo!

Of course. It's not really all *THAT* difficult to work out, surely?
