I am running the 15A current through 1.5 mm² copper wires, connected with the Wago 221-413 connector. I measure different temperatures: internal and external of Wago, wire temperatures. The room temperature is 25 ° С. I have shown a graph of the temperature increase. Guys, what do you think about this video format? Would you like to see the next full tests without acceleration?
Why? Do you think wago 221 would be certified for use (or even manufacture) within EU and bear the CE mark if it couldn't withstand nominal current loads?
@@stazeII And I don't get it why, because the commonly used wire nuts are such a pain to use correctly, and also if you have to change the wiring, all your cables are messed up.... Especially DIY people should use Wago as IMHO they are easier to change and easier to use correctly.... Now I sit back and wait for the hate comments of the wire nut fanboys....
@ cause we’re stupidly stubborn sometimes. Cause “I had to use wire nuts, so should these damn kids”. And yeah, would think properly using wago (easy) is better than a poorly used wire nut.
@@stazeII yeah, cos they fear that the springs clamping force would be the culprit of their shacks burning down :) but horribly twisted solid core wire with a cone spring will be safer :D
@rolandrohde Of course, you can use 1.5 mm² for sockets. In this case, the load on the cable must not exceed the allowable limit, and it should be protected by an appropriate circuit breaker.
This model of connector is rated to work in ambient temperatures (85c) that exceed the operating temperature of most standard PVC cables (75c). They are rated to carry fully current continuously under such ambient temperatures and will rise to 105c. The specs are published by Wago in their datasheets. The insulation on standard PVC wiring will have failed at 105c with a very high probability of push-through. Even wiring that permits 90c will be on fire before the connectors show signs of distress.
Thank you, your channel is fantastic, love you videos really useful, will definitely be requiring my apprentice to watch all your videos as they brilliantly illustrate the regulations. It would be really interesting to see some other cables being tested low smoke, h07 ,silicone sy, ny,fp200 ,in there 3,4 and 5 core configuration. And if you are interested in doing requests at the moment I'm very curious to know what happens to the temperature of cables when expanding foam is used to Bury oval thinking in walls , I was going to do that myself if your fancy doing it for me I won't complain:-)
@joeatkin6600 Thank you, my friend! I’m doing this because I want to better understand electrical and physical processes. It’s really nice to hear that you’ll be showing these videos to your apprentice. I have to admit, every new format or genre takes time because I’ll also be doing it for the first time! I need to take care of the materials, script, and filming. I also start with trial tests to evaluate how accurately I can convey the information. Sometimes challenges arise that require solutions or additional expenses. You’ve sparked a few new ideas, and I’m already working on some of them!
I recently wired up a brewery lots and lots of adult sized circuits, , all the cabling was either as per the regulations or oversized, and I was genuinely surprised but when the place is going full Tilt how warm some of the cable trays get. It's all 90 degree cabling so I'm quite happy with it, but even an old hand like myself was genuinely surprised
I will conduct tests at different currents to better understand the temperatures the contacts heat up to. Yes, it’s likely that Wago can handle 32A (it won’t melt, but it will heat up significantly). In my opinion, most electricians use it with currents of 10-20A and want to be sure that the heating temperature will be negligible.
Thank you for the comment. In the left video, the sensor is connected inside the Wago and touches the contact plate. The temperature there indeed reached 42-43 degrees. However, the external temperature of the plastic (what the thermal imager measures) is lower - around 36 degrees! That is, the difference between the internal and external temperatures in these conditions is about 7 degrees.
Some people eh you give them all the data all the proof and yet they shun away and keep making inferior connections. I find it funny how half of european electrical installations are solely build with Wagos yet you see no complaints. The other half is old installations that predate Wagos.
@alouisschafer7212 I service equipment that can be up 50-60 years old, I've seen failed plastics (though modern ones are better in general), even good plastics in bad conditions deteriorate, and can lose tension in case, that is why I won't trust any of these for kw+ loads, they just make no sense to me whatsoever for someone who wants a quick install and doesn't care what happens in 3, 5 or 8 years, sure, these are awesome
I think you've done a good job of presenting multiple relevant data points under clear and well-defined test conditions. However, I really don't see what the point is to doing this sort of test for WAGOs this late in the game. There are already many, many (many) other videos out there where people have already shown the same thing over and over again. You're not really contributing anything new to the discussion. Since you're showing the temperature of the wires, it would have been good to actually tell us exactly what gauge of wire you're using. Also, an in-circuit ammeter is usually a bit more precise and reliable than the clamp kind (though probably not a big deal for this particular test). In any case, I think it is worth noting here (as with many others I've seen) that the temperature of the WAGO was basically the same (or less) than the _temperature of the wires_ the whole time. The reasonable conclusion is the wiring can take the current, the connector can take it too.
Thank you for the detailed comment. I do the tests primarily to reduce debates about the heating of different connections under various conditions. Of course, for this I will need to conduct many tests. This is one of the main focuses of my channel. Regarding the ammeter - my test setup includes a more accurate one. I look first at the main ammeter, current clamps are for duplication. Yes, under these conditions the wire and clamp performed well. In the first comment, I mentioned that the wire is 1.5 mm².

ac or dc how many volts
You should do 2 more tests on 2.5 wire and 4 wire and see if you get the same temps with 16 amperes.
@kevin_huber_at alternative current
"Will Wago 221-4 withstand 15 amps?" - Given they are rated for 30 amps, I would certainly hope so.
Thanks for the comment) I also hope that they can withstand 30A)
given that youtube has video evidence of them running 100 A, they surely will....
Why? Do you think wago 221 would be certified for use (or even manufacture) within EU and bear the CE mark if it couldn't withstand nominal current loads?
At least in US, there is an annoying distrust of wago’s. Glad to see stuff like this.
Not everyone trusts certificates. Besides, it is interesting to know how different parameters affect heating.

In household 1.5sqr mm is for lightning. I wonder how 2.5sqr mm would look like. The copper would suck quite more heat out of the connection.
I agree. Wago-221-4 can also connect 2.5 and 4mm2. The heating should be significantly lower!
Not so sure about the use in households...as far as I can tell, pretty much everything in our relatively new (2009) house is based on 1.5mm2.
@rolandrohde Of course, you can use 1.5 mm² for sockets. In this case, the load on the cable must not exceed the allowable limit, and it should be protected by an appropriate circuit breaker.
@@ElectroTest_1 well yeah...circuit breakers are all 16A here.
@rolandrohde According to the European standard, this is acceptable but on the edge. In addition, it is necessary to consider the specific situation.
This model of connector is rated to work in ambient temperatures (85c) that exceed the operating temperature of most standard PVC cables (75c). They are rated to carry fully current continuously under such ambient temperatures and will rise to 105c. The specs are published by Wago in their datasheets. The insulation on standard PVC wiring will have failed at 105c with a very high probability of push-through. Even wiring that permits 90c will be on fire before the connectors show signs of distress.
Thanks for specification data and your opinion! I would like to test the connection at higher temperatures.

Excellent!
Thank you! It inspires me!
Since these wagos are rated for 32A and 450V why did you not test those? That would have been a much more meaningful test.

and now the same Test with an old 1 Screw Luster Terminal and some 1.5mm Copper Wires .. just für Fun
Thanks, good idea!
Wow. 20 degrees above ambient. You've really rocked the scientific community with your autoranging Temu imager.

In the US, 15A fuses are common; in Europe, 16A are common. In England even 32A but the plugs have fuses.
The volts don't matter.
Thanks for comment!
tell that to poor ohm's law.
still wouldn't use this for anything permanent above couple amps
