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. Great vid Batman, love the science side, also big thumbs up to John Ward.

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.

The Wago failing like that is a good thing it acted as a fuse and possibly saved the house burning down. It still survived WAY over it's rated current and unlike the terminal block which seemingly was better hasn't screws to get loose over time. Long term old style terminal blocks are far more of a liability.

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.

@westinthewest 3 жыл бұрын

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. I've seen many of those suffer with continuous heavy loads which they should have been fine with. Fused spurs are usually unnecessary for fixed loads, so I always avoid specifying them when regulations say they can be omitted.

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 . But does show the dangers of what happens when loading is not taken into account on any electrical circuits. Keep up the vlogs Nick

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...

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.

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.
