Overloading Cable Connectors, Electrician

[@leonblittle226]

The connector block compared to the others did well, but it's a big lump of metal which just goes to show they aren't bad if installed correctly with some care. Everything took more than double the rated load before it started to go wrong which is comforting to know.

[@andyroberts3675]

Manufacturers will always give themselves so much room in the ratings charts, much like supermarket use by dates, they go well over to cover themselves

i wont think is a good thing to have the cable be the most likely point of ignition. if the connector would have failed at its rating with out a spark now that would have stopped the chance of a fire. after all the circuit is now broken.

[@Thermalions]

@@highkicker11 I'm no Sparky, but I'd have thought failing without risk of spark isn't part of the design requirements of these sort of connectors. Isn't that what the fuses are supposed to do (assuming they haven't been bypassed)?

Judging by the amount of current that the cable can take and the connectors, I feel safer when using them as they can take considerably more than their rating factor. It just goes to show, as long as you have the correct sized breaker the installation should remain safe..... Assuming correct installation and to regs of course.

It was good to see that all the connection method held above the rated specifications. For this to happen in the real world the overcurrent protection would have to fail. Wago failing might not be a bad problem at failure point as it opened the circuit whereas all others would have kept generating more heat. Nice video glad you kept staying safety precautions.

Presumably these are all performing well above the rated current due to the very favourable conditions here: open air in a cold unit.

To be honest, I expected the 'chocbloc' connector to do well, if a good initial connection was made, it's when incorrectly connected they suffer. Examples like overtightned screws and threads stripped so connection tension is lost etc.

You have to take into account that you are using a lower voltage but high amperage, also that the welder will be using a DC direct current not AC alternating current , so you are testing these connectors not directly in how they would be used in peoples homes, you should also have a proven amp meter in the circuit and not just trust the welder dial .

[@rebel4466]

The problems in installations usually come from bad jobs or connections that have been worked on. The connector block is great if you seat everything correctly once and tighten it down with the appropriate amount of pressure. Even better if you use ferrules. But if you work on the connection or don't use ferrules and only clamp down certain strands while others are either loose or damaged, things can get funny fast. If you take care and do everything correct, you don't have to worry about all the options. Question is which is the most likely to be used in a wrong way? That's where the Wago shines in my opinion. You can disconnect and reconnect pretty much as often as you want and you won't get a damaged cable, while being able to see through the thing to make sure the connector is well seated.

[@Dan-vw6sf]

Surely the wago failing in this scenario is a good thing if it interrupts the current and prevents fire?

[@Interknetz]

With my computer and 2 monitors, plugged into an extension, no issues. Wild part which will most likely trigger you, I plug a portable AC into an extension that is plugged into the extension my computer is plugged into. However, I have checked during the summer when both are on (and I don't run the AC full speed given my room is small), and no issues with heat. I probably ought to check what amps all these things use next time summer rolls around...

[@izools]

This was an awesoe segment dude, thank you. There's probably a discussion to be had about DC amps from a welder vs AC amp,s from a ring main, continuous current vs RMS current, and the effect the difference has on current handling of a given cable... but we'll leave that for another day... Or for JW :) What is enlightening is that the oldest type of interconnect (screw-down block connector / chock block) had both the best current handling and the best mechanical integrity of all the types of interconnect. Do you think this will change how you join cables in future? Wago are easy to install... but you've just proen they're the least reliable in a fault condition...

[@b96m13]

[@christianclark1354]

If the insulation has melted off the entire cable then I think we can forgive the Wago... In this case it acted as a fuse and turned off the 2.5mm house-sized heating element 🤣 I once bought 2x "refurbished" stage lights from eBay which both contained undersized old style block-connectors that were extremely hot and actually melting the outside plastic of the device and was severely burning inside!... so, it's not a case of "block connector is better than a wago" it's a case of using the correct tool for the job. If either is not-rated for the amount of current it's a fire waiting to happen. In some ways the Wago is actually less dangerous in the hands of an idiot because it always applies the correct torque (screw-down connectors can be under or over tightened), and as they just look a bit flimsier so people don't just put them in without stopping and reading the rating which is printed on them, unlike most terminal blocks.

[@markhutton6824]

So you tested why beyond he specifications on the wire and the connectors are was surprised they failed. Not sure how this is a test of anything. I have WAGOs in my ceiling lights, most of my electrical requirements in my shed. I start the platform drill powered my basic three core cable and the joints are WAGO and never a smell. When I start up my grinding discs there is no issue with the electrics. Because the WAGO I use ae rated to 30AMP... an electrical oven is 30AMP... as long as you aren't using WAGO for the mains electric coming into the house then what its the issue?

What is the gauge of the conductor (at 4:04 you said rated for 34 amps)? At 30 amp the gauge of the conductor should be 10awg. 50 amps should be on a 8awg, etc. As you go higher in current, the conductor's gauge should also be larger width (smaller gauge number). Likely the heat of the conductor is transferring to the connectors. If the experiment is not valid, which may be the case, then it may mislead others. Also, yes the Wago if it is 221-412 is UL rated for 32 amps.

[@benjaminw762]

I've always wondered, what's the fundamental issue with extension leads in to extension lead? I get it overseas, it's easy to overload a socket. But in the UK each extension will have a fuse in the plug right? So even with multiple extension leads plugged in to each other you shouldn't be able to exceed 13amps for all plugged in devices... Wouldn't the fuse in the first extension would blow first? Am I missing something?

[@speedmytube]

You're right about 13A fuse in total but that is still quite a lot of current and plenty to start a fire (240V * 13A = 3000W = 3000 Joules of energy every second - a match head has about 1000 joules of energy for comparison so three matches every second!). The more connections, the more likelihood that one will be a loose connection that can overheat. Remember that all the connections are in series so the total resistance is the sum of each individual connection's resistance. Also, the more extension leads, the more voltage drop from the cable too.

My concern with Wago type connectors is how they will perform over time, I understand and have seen screw terminals that become loose over time, I know the test was very extreme, but interesting to see how the choc block did.

[@fajnbrambor1856]

Sorry for late reply. You see, unlike screw in terminal/block, Wago uses spring loaded metal strip. That means, when you close the lever, it will put pressure onto the metal strip, which subsequently firmly grips the wire (in my personal testing, it grips really well and it is pretty much impossible for the wire to come out without big external force). The advantage of this is, that this mechanism cannot get loose unless the lever is opened or the case undergoes catastrophic failure. As you saw in the video, Wago easily withstands over 100 A and started failing at 130 A. It started to fail at 6.5 times the rated current. So unless someone is trying to put these connectors where they are not supposed to go, you can be pretty much sure, that this connector might, and most likely will, outlive you.

I was amazed to see how all those day-today connectors we use are under-rated by the manufacturers, but I've found that it's the opposite when it comes to 13A plugs and FCUs.

Fused spurs are usually unnecessary for fixed loads, so I always avoid specifying them when regulations say they can be omitted.

Wago 221s are 32a? Plus what torque do you have in the block connector screws. 😂

How did your own wall socket do? Could’ve opened that and had a look and shit a thermal at it?

Clamp meter for actual Amps, and take a voltage readings to work out the power. W=I*V 👍

So which would be best to extend the ring tails inside a CU? I was thinking Spliceline?

[@amblernectar]

Depending on the cable size and current draw, a WAGO 221 upto 2.5mm and a WAGO 773-173 from 2.5mm upto 6mm work out well.

Great work as always. Thanks for the awesome content stay safe and take care

See why I think connector block is better than a connector that’s relying on sprung tension like a wago. Always said I’d rather be making the connection by lightly twisting cable cores then over both screws of the connector block into the same side.

40.2k subscribers when I watched this - congratulations. The wago has the least copper in it, so not surprising that it was the first to fail. I wonder if the connection pressure of the wago was also affected by the heat. That looks like an inverter style welder, so as per below, would be interesting to see a true RMS clamp meter reading the current to see how it compares to the readout on the welder.
