The pertinent factors here (apart from price) are speed and pressure/tension. Even if screw connections can be made quicker than constant pressure connectors (which only some people could do), constant pressure is the important safety (re fire and repairs) factor that makes them the far better connectors to use. All we need now though is enough people to buy this range, or other manufacturers to compete with MK, so the price drops.
Prices will come down
Anything that helps with time and potentially reducing the risk of arthritis is a win win
The thought that you think less of me because I run my contracting business using a hand cart, wear clogs a flat cap and donkey jacket, still use bakelite electrical gear, VIR cable where possible and the loverly BS 3036 fuses. Remember electricity is the future one day every house will have it
😂😂😂
".. those people that go to work on a horse" 🤣🤣👏
🤣👍🏻
If the terminals work like the Wago 221 you don't even need to open the levers to get the wires in. Did someone test if that works? And I had a laughter at the "sausage finger" expression, we got that too in the German language (Wurstfinger) meaning exactly the same thing.
Yes we tested it - you can’t push the conductors in. wurstfinger we’ll be using that - Thanks Marcel 😄
Ah men about time defo the way forward 👍
Trial run on just a double socket & only being available for now at a certain place to buy is without doubt going to have tiny push back Wondering how levers will work in a single socket, FCU & any light switch We’ll have to wait and see
Im all for these upgrades to sockets and fuseboards. Dont like MK but hopefully all manufacturers do this
When using screws, you should double over the CPC’s. Which equates to more time…….time not spent when using the maintenance free socket terminals. Some may even double the Live and neutral cores!
i saw someone reviewing the same socket on like a electricians facebook group, many people said "ah its for low voltage" little did they know this was made by MK !
I would like to see a plastic U piece just before the lever terminals.. About a few mm from the lever terminal. Push the conductor in, then any stress from cables behind is put on the U piece, _not_ the terminal itself. Similar to having a cable clamp, but no screw involved and no pressure clamping of the conductor.
Good for us DIY'e as well (cue the stream of hate...boo...hiss!!!). It's not about speed but quality of connection for me, no more doubling over and knowing how much to screw down etc.
Let's face it you wouldn't be going at that speed day in day out. But the push fit system is quicker regardless of what people may say. I have said for a long time it should be in fuse boards, that way it will stop the idiots causing board fires. Imagine giving those electricians that are negative about these sockets, a brace and bit for drilling joists, a Rawl tool for masonry and the good old Yankee screwdriver with slotted screws, I wonder what their reaction would be then 😂
We've got hold of some Wago terminals which handle 125A !
@@efixx wow 👍
@@acelectricalsecurity You say idiots causing fuse board fires, I went to another job yet again yesterday where the meter installer hadn't even screwed the tails in from the fuse head. When the customer was under the stairs getting a gas reading they knocked the cable out. Considering they seem to average about a days worth of training I think meters should have these connections before consumer units. Thankfully no one died but it's becoming a little concerning how common it is to find faults with the metering equipment caused by rushed installs.
@@effervescence5664 yeah that's true, I have had several installations where they had a new meter prior to when i get there, and have put my tester on the installation to see it going bannas, then I find they have got the polarity wrong. But the society we live in, everyone has to be fast tracked, quicker is better, lost count of the amount of jobs I go to, where the customer asks how long it will take, I tell them, then they say the other guy was going to do it faster, so I say get him.
Many of the consumer unit fires I've seen have been at the busbar where its made little to no connection for years with the often client reporting an intermittent fault on the circuit before the smell of fish and then the obvious fire 🔥 even I've missed the busbar screw. Defo a place to triple check!
Amazing that it's taken so long for this development, but why are there only three levers on the earth? Surely a faceplate on a ring with a spur and a metal back box will need four levers on the CPC...?
current MK logic plus sockets have a single cpc terminal - terminate all the cpc conductors into the backbox and a flylead to the socket faceplate.
Metal backboxes with one solid lug need to be used. Or looping the CPC into the earth terminal on the backbox - *without cutting the CPC conductor.*
Gotta be the way forward. I mean, would you rather jam 3 wires into 1terminal or 1 wire into 1 terminal 3 times. One thing I'm thinking though, especially with consumer units and the need to remove conductors for testing: At what point does the factory torque weaken and how is it checked?
Good question - we'll explore this with wago.
Pretty certain they are good for many many many opens and closes, not had seen issues with wagos losing clamp
@@efixx Wago have told me they are checking with MK regarding force gauge pressure tests to ensure they match up with their own connectors labeled as their own. Hopefully they are just as good.
@@s.kxx1956 based on what evidence?
@@ascot4000 yes it’s a whole bunch of things that matter material quality, tensile strength, geometry you mentioned and here there maybe compromises in term of having sufficient good geometry to keep things in place but still allowing air to circulate to reduce thermal wear over time. I wanna know from the manufacturer that these tests have been done and they have the results to prove it. We have UL listing here in the states which helps to differentiate better tested and capable products than those that have not gone through that process. Making them safer and appropriate to use in the right situations our standards refer to use of products with this kind of laboratory/engineering testing, separate from manufacturers own tests.
Desperate for scolmore to put this into the click range 🤞🏻
It’s been in the updated BS1363-2 since 2018! No one has rushed this through!
How are back box fly leads accommodated when spurring of the ring using these sockets.
Exactly. It seems an extra CPC terminal should have been included for that purpose. 🤔
Just fold the Cpc from the spur and use the back box terminal.
@@efixx Can't they provide an extra lever connection workrounds tend to take the gloss off a new product.
@@efixx That'll work. It's still an oversight though. 😁 Mischief is my middle name! 😋
@@efixx that is super naff in my opinion, looks poor and its gonna be the first place the cable breaks when removing and replacing faceplates
great video guys, its a lie if someones quicker on screwed terminals! If you can answer a question a bit off topic but does anyone know where the rule of not running flex more than 3 meters in a house came about? looked into it and cant find a reason as to why you're not allowed to, but seems too be a myth many electricians go by... cheers guys.
You can use flex for fixed installations so we think the 3m is a myth.
I like the idea of them as specially for two day and five day corse junkies, but I prefer the screws, I don’t need to rush , when you rush you loos concentration and make mistakes and that’s when you end up killing someone if not you’re self. As for over tightening the screws and damaging the conductors? Isn’t true, I have always tightened the screws till they stop and have never never broken or damaged a conductor , . Isn’t that the reason we double the ends over to give the screws something to bite onto and insure a tight connection secondly conductors can be pulled out of wago s David Savery did it in one of his videos . So I think the argument about loose connections is dead. But would I install those sockets ? Yes if that’s what the client wants and they buy them there self . Great video guy’s as always 👍❤️⚡️
It’s not just about speed it’s about reliability and safety of the made connection both at installation and over time-say 20 years. From a cost perspective v time saved - on a new installation or a full rewire it is highly likely to be cost effective on a socket replacement not so much.
Any plans for a metal clad version?
I’ve emailed MK and asked. They said they are waiting to see how much appeal it has first before extending it to other ranges.
I knew about these months AGO but didn't want to tell you about them. I'm not into spoiling the surprise. Anyway I digress, did you receive those Plain Tickets?
Can you change the tickets 🎫 we’ll be doing the trip via our friend in the Caribbean 😄
They have had these on commando sockets from rexel for ages
It's the screw makers I feel sorry for.
A very useful product analysis. However, I've seen on other channels that this might encourage 'Joe Homebase' even more to have a go at replacing sockets etc. Do you think that this is also a 'safer' option for those who would be looking to do this?
We have a DIY guide from 1949 which gives instructions on how to change a socket. This product is what electricians have been asking for. Improved reliability of connections and faster.
@@efixx and until at least the 1980s, consumers in the UK were expected to mount plugs on every appliance they bought. Is replacing a socket - not extending a circuit, not doing fancy intermediate switching, just replacing a socket - really any more complex than that? *really*?
Imagine a push fit consumer unit 🤔
They look quite deep so will squash conductors in the backbox if used a std 25mm ko box.
OK - I went back and looked deeper - I found them in SF. Five for £30, that is 50% more than the screwed Logic Plus but I bet if they start to sell then the price will drop and the screwed terminals will be reduced and stocked just for the die-hards who never admit progress is a good idea. It's strange because you'd think they would have less free time, having to feed their horses and muck out the stable when they return from work.
Prices?
Link in description to Screwfix - exclusive to them atm
Speede II exists.
we know - kzhead.info/sun/eKqhfatuZJWDqWg/bejne.html divides the efixx team
Trying to make off connections as fast as possible. Unbelievable as it’s probably the most important part of what you do .
It’s to prove a point not a mantra for a real installation.
Fair comment , just winced when I saw non doubled cables being terminated into the screw terminals , shocked by how many new installations I’ve come across where this seems to be the norm , hats off to MK although the price might deter people .
None of them are testing to see if the wires are stuck, by pulling on them a little.
all about the speed in this race
Replacing 1 socket not worth it... 600 flats quids in
This termination system solves a problem that doesn't actually exist. Termination of outlets is a small part of the job compared to everything else.
Electricians have been asking for screw-less terminals for ages. In the rest of Europe they’ve had them for decades.
@@efixx I don't think the intention is to solve a problem, rather to make an improvement, which these do imho. Where the levered terminals would be of benefit is in a ceiling rose, especially if it were somehow designed to line up with the screw holes and fit inside of pendant lights that are sold with a simple three terminal block. Again, imho😊
@@efixx efixx will have to send Gaz over to foreign parts to bring some samples back so we can see what we are missing out on I bet our version is much superior to those made on the continent
"Solves a problem that doesn't exist" That's why Wago connectors have all but replaced screw terminal blocks in other applications?
@@efixx I can see the case for wagos. We fit thousands of them each year. But with these, you aren't covering the extra cost of the outlet vs the labor to install. My situation may be different here in Australia - our labor rates are HIGH and the materials costs are probably double what you are paying for. Basically - the labor cost saving is moot by the materials cost going up. You are literally saving pennies, by paying pounds.
So you saved 80 seconds over 5 sockets, or 16 seconds per socket. Even at £90 per hour that is still only a saving of 40p per socket. It's pretty hard to justify these on time saved for installs under good conditions. And justifying them on quality of connections is awkward because it's only double sockets, any real install will contain other accessories, so you can't offer the customer a fully screwless install. Where I could see these being a boon is for installs under adverse conditions, sockets in difficult locations, existing wires that are too short etc.
in my opinion this is compleatly useless.
Why is that?
