The annoying thing with the Wera Torque driver is it comes in at least 3 variations:
7440 VDE 0.3 - 1.2 Nm
7441 VDE 1.2 - 3.0 Nm
7442 VDE 1.7 - 3.5 Nm
Now many RCBO's currently are 1.2nm on the out going side and 2.5nm on the bus bar, yet main switches can be up to 3.5nm so you either need 2 different Torque driver handles or to swap consumer unit brands you install.
I have a lot of Wera stuff these days and they're good tools and kits, yet the Torque driver handle really lets it down considering some manufactures are going from 1.0 - 5.0 Nm - Wiha/Draper for example.
Good information.
Fantastic piece of kit. Great overview mate. Love the 'slight technical hitch' :D
Ha ha thanks!
That was my favourite bit! 😂🤣😂
i was going to get this until i did as you have and checked the hager site, and noticed the setting for a main switch is 3.6, and the highest setting you can get on a wera torque screwdriver is 3.5 on one of their models, which is crazy when others make them from 0.1 up to 5.0
Nice kit ,however if you have the money get the Wiha Electrical screwdriver as it includes a 4mm hex needs for commercial Eaton boards.
Although the wrenches don’t go high enough.
But Meter tails can be pulled out when done to recommend torque settings.
Nice one , I've got the Wera maintenance kit that comes with all the bits + a socket set and uses the same size bits as your kit , I bought a Wera T driver on its own for about £ 50 and all the various sizes of driver heads fit plus sometimes you need to torque up small nuts in some C/U s and the Wera adapter will also fit the T driver , doing it this way is a lot cheaper + less kit to carry around with you......👍
Nice yeah I’ve seen those they look good
I find my experience is enough to tell me if I am over tightening on a terminal. I was talking with my assessor today about all the latest 18th edition changes and how much is manufacter led. Tools, AFDD's, SPD.s, metal cable clips etc etc. The people who write the regs are being influenced by the people who sell all the gear and of course sell us the new books. If the IET was all about safety then the regs book would be available as a free download. Too many vested interests in an industry that is more interested in making momey out of hard working sparks than improving the quality of workmanship and ensuring a decent living.
I know what you mean about the regs books, it’s a killer to have to pay £80+ for a book that you know you will have to throw away in a couple of years time
@@artisanelectrics don't throw them away... They are useful for doing periodic testing of older installations to see if they were up to code from install date.
As an apprentice I paid £20 for the 16th edition because it was a knock off version. The guy made a small fortune selling those to us. Car boot full at lunch by end it was empty and he had probably made £400
Please return it to 0Nm after use. There is a spring inside and as you increase the torque it stretches the spring. If you leave the spring stretches it can weaken the spring and give you incorrect torque settings.
Great tip thanks!
Noted- cheers!
Looks like I'll be getting a new set. Wish i knew this year's ago, been using it since.
Just about to say the same thing and then read this.
Sweet set of screwdrivers there
Yeah!
The one you recommended it goes up to 3nm,and Schneider mcb anything above 25A need to be set to 3.5nm.
Wera 7444 cover that range
Second does it need to be different settings for CPC and neutral bar?if yes where do you get that information please?
Great video
£100 ish for that? Extremely good price if so! Ive paid over that for one or two non-torque VDE sets from Wera! I’m not a professional but have been making up KNX panels etc (as well as other small jobs around the home) and have been meaning to get a torque driver for a while. One little job (I know many would do without a torque but not a great idea) coming up so I had better get the driver stand-alone in preparation!
Good job
Thanks!
I have a wera raft form kompakt vde set but not torque and I wonder are the blades inter changeable?
I’ve always just tightened enough to personally know it’s physically tight and isn’t going to come out, do I need to get a torque kit, tips and advice welcome
Great vid ,would be interesting to see if the tip fits an Eaton mr30 pod
I will let you know when I find out! It’s pretty thin so should do!
You should only go one click. Every click represents over torquing - technically the first one is over torqued but there's no practical way to avoid that. I previously worked in mechanical engineering and had a meeting with a torque wrench manufacturer and that was what they said.
Thanks, great tip! So happy to have a female viewer! Stats show my audience being 98% male and I was hoping to change that somehow.
@@artisanelectrics Haha! I think it's a reflection of the industry - I actually work predominantly in temporary electrics and stage lighting rather than install work; but whenever I go on a course, I'm used to being the only lady there!
Well you’re very welcome! Thanks for watching!
YES! Otherwise I guess you are using it as an impact driver...
I agree with you.
I've put off buying one of these for a while, I've been using a cheaper but uninsulated small torque wrench and taking care (with power off) but delayed it no longer. The need for such a tool is clear if only to prove the correct torque was applied - no such tool, then they couldn't have been torqued up correctly. Two questions: 1. There is a requirement to have the wrench calibrated, when, cost and need? 2. Do I need to fall off my chair every time I tighten a live terminal ;)
Ha ha great comments glad you went for it! Chair falling is essential!
What torque setting does Wera screwdriver go to
Nice bit of kit, was looking at getting one myself, they look so cheaply made though?..calibration?, if NICEIC etc don't ask to see proof of cal, whats the point really?.. I like to do things right like you, but sometimes we make a rod for our own backs. Tighten it as good as you can, I have always done this and without failures. Even if you torque the terminal to the manufacturers spec, a few years down the line that terminal can come loose due to frequency in the mains supply (yes it happens), or someone coming in after you to add some other circuit.. where will it all end?.. Great video, thanks for the unboxing, showing how to use it, and the "technical hitch"..I almost fell off my chair laughing :-) I think the screws need torquing up ha ha.. Just ordered one thanks :-)
Awesome thanks for your comments!
How do these torques drivers differentiate between correct torque and a badly formed thread or screw?
They don't but nobody likes to talk about that problem and the resultant loose connections.
That's a good range of torque settings but I really can't see the value in carrying around all those different driver heads - reality is you will only ever use the PZ2 one.
Yeah I know what you mean but they are useful as normal screwdrivers even if the Torque is not needed
Nice vid - quick question, I'm just about to buy one of these but looking at your video it says 'single cable >1.5mm (i.e the tails) in the switch disconnector (isolator)' should be 3.6NM how do you achieve this when the screwdriver only goes to 3.0NM ? I'm new to these screwdrivers so hopefully something simple I've missed ...
Get the Armeg Set here, they go up to 5nm amzn.to/38IiazH
@@artisanelectrics nice one !!
Don't quote me on this but I think the torque settings are listed on the labels sheet you get with a new consumer unit. Some manufacturers even provide that information within the board, such as on the busbar shield.
All Hager boards come with the torque settings within the instruction/installation
6:00 for the adjustment
Can be a bit iffy on tails, tighten it to a click (at manufacturer specified nm) but you can pull them out so easily after! You end up having to tighten it to a click, wiggle the tails back and forth to re-arrange the strands then tighten to a click again & repeat until wiggling stops making a difference!
But like you've said in the comments yourself, better off doing it by the book. At least that way your arse is covered
Interesting point thanks!
Great job and video, would you recommend any books I could buy as a trainee electrician, for my level 2&3 diploma electrician course this September ???
Have you got this one? amzn.to/2WcV7cf not read it myself but looks good.
Artisan Electrics haven’t brought any books yet, as I don’t start collage until September but this one look interested, is it similar to this one Electrician's Guide to the Building Regulations (Electrical Regulations): Amazon.co.uk: The Institution of Engineering and Technology: 9781785614682: Books

Great video! It is necessary to prepare this kind of insulated manual screwdriver. Not long ago, I bought this kind of insulated screwdriver of the renhotecic brand. During normal use, it is very safe. Everyone can prepare one if needed.
is there a calibration certificate issued with this ?
So how much different is the 'correct' torque compared to what you have been doing all your life?
Interesting question! I will have to do a test!
So when you used the Wera, did it click before or after the point you would have stopped normally? My money is on before.
Yeah usually before I would say
how do you torque the isolator when the screwdriver only goes to 3Nm ???
Then you need a higher torque screwdriver
@@artisanelectrics which one would you recomend that will cover the higher torque setting or covers the full range needed
@@andrewlougher-harris5492
The Wiha VDE torque screwdriver goes up to 5Nm. It is about twice the cost if the Wera one though and more of a faff to adjust (you need the special tool supplied). It does have the advantage that the bits are slim profile (the insulation does not increase the thickness of the bit meaning that recessed screws are no problem).
@@stuartarnold9444 thanks , been watching some how too on y-tube and there seems to be some important setting marks missing eg 1,7 and 2.3Nm it is putting me off pulling the trigger,
Can you use Bundy10 for discount?... Asking for a friend
i dont know why people would give you are hard time for not using a torque wrench, maybe its a london thing because they have so many fires from limp wristed electricians there, after all it was the london fire brigade that pushed for metal consumer units, i guess its not called the big smoke for no reason, ha ha, joking aside, you know when a terminal is tight, its like everything, a few years ago no one would have give a crap, now all of a sudden everyone is using a torque wrench, yeah right. Its all down to rushing about and not taking care while doing the job.
There is some wisdom in what you say, but over tightening can be one of the biggest problems, it’s not just that it’s tight enough. I say best to do things over the top than under.
@@artisanelectrics your right about over tightening, but when you have been doing the job for a long time, you know how tight things should be. What could happen is people will torque things up, and think job done, however especially with meter tails, they will come loose, they do need to be really tight, probably more than the torque setting.
3nm is not a lot surly it's only for people who haven't a clue and over tighten stuff or will they need calibrated evey other week to be precise.
great videos, but your audio levels are soooo low
Thanks I didn’t realise
Audio is fine.
Where are foot lbs
imagine if a painter and decorator had to fork out for all the tools a sparks does ?? how much would they be charging for a room to be painted ?? i mean if instead of the thirty quids worth of brushes and rollers and that sad little bit of glass paper they carry around cost a couple of grand ?? yet people whinge about the cost of a rewire but happily pay a few grand for a hundred quids worth or paint !!!
Ha ha good point!
the audio on this was near as dam useless, you failed to say at the end of using the torque driver to return it to zero, so in essence less than half the job done!
Pity no video only audio
I know my opinion on them
A
I use a battery screwdriver...when the motor stops it’s tight lol
Which battery screwdriver do you use?
Another gimmick in my eyes. I’ve survived so far without one ?
We are already required to install equipment to manufacturers specifications, by not torque tightening the screws, you are effectively not installing to manufacturers specifications.
Regulation 134.1.1
You hit the nail on the head there
Lets just say that in industrial circles where equipment costing tens of thousands of pounds is manufactured and installed as part of multi million pound contracts, torque screwdrivers are not widely used.
Interesting... I’ve worked on huge three phase boards in the Netherlands and Torque Screwdriver was a requirement
Armeg better
I’ve got both now. Armeg video coming soon
@@artisanelectrics Great. I'd like to see that used on C/box to show how the Torque works 🤔. Love the channel AE
cant hear a word he's mumbling
Get your ears checked out.
Are you advertising Amazon to buy from them because on eBay you can get it cheaper
