How to use an ELECTRICIANS' TORQUE SCREWDRIVER: PLUS Tips to look after one! : Wiha TorqueVario.
Переглядів 34,742
День томуSetting the correct torque for an electrical connection is essential for today's electrical installations. With more electronics and miniaturised circuit protection devices appearing, tightening to the wrong torque setting can lead to expensive and possibly dangerous mistakes.
A torque screwdriver is an essential piece of an electricians kit. In this video, we show you how to use an electrician's insulated torque screwdriver. We'll be using the Wiha TorqueVario-S VDE electric to demonstrate. We also share some top tips to help ensure a long tool life and trouble-free tightening of electrical terminals.

I'm so glad you covered the different kits you can get. I've been meaning to pick up a torque screwdriver but was a bit lost as to which set was right for me
@FNUKSTER1366 2 роки тому
When finishing with the torque screwdriver always unwind to minimum torque, saves stretching spring + keeps it more accurate
@tonymartin3780 2 роки тому
Hi Mat if you don’t mind me saying you don’t need to unwind back to 0.0 >>> it designed to stay where you set it , it’s most important that you don’t unwind more than the 0.8 or 1.0 Nm marker >>>> over wind by the 5.0 Nm >>>>> marker hope this helps.
@ianstanley5157 2 роки тому
Quick tips ... The little wiggle of the wire between the loosening on the terminal and the final torque. A dot with a sharpie at each terminal as soon as you have done the final torque, that way you never miss a terminal and the person after you can see straight away that you pay attention to detail. Lastly the mirror to make sure the wire is inside the terminal, another common problem.

I recently decided to replace all my screwdrivers and was trying to decide between Wera and Wiha. I did a lot of research to weigh up all the features and benefits. In the end I chose Wiha. The Wiha torque screw driver and SlimVario system had a major contribution to my final decision. I'm now embracing Wiha tools with no regrets. Very happy customer 👍 Thanks for your videos, guys. Mike.

Another interesting vlog guys . I’m in the partly a believer camp due to my frustration with modern poor quality cheap as you can make terminals especially main switches and some cables being poorly made work hardened not annealed copper bar in pvc labelled as cable . I do have that very screwdriver kit and found some cables did NOT grip the conductors in a satisfactory manner . As I have mentioned before you need to wiggle the heavy cables in order to rearrange the round conductors in a square connector😏

if by mistake I have a screw tightened to 1 NM and i use this tool with a lower setting like 0.8 NM to loosen the screw the tool will click and won't allow me to turn. does this damage the accuracy of the tool ? and can you use the Vario S VDE bit holder with standard Vario S (non VDE) handle?
@eric72 2 роки тому
Something to try. Put a suitable adaptor in an impact driver to fit a 10mm socket. Use this to tighten a nut and bolt. Then loosen the nut and bolt with a spanner. This will demonstrate just how much an impact driver will tighten things.

@billsbasementworkshop1902 2 роки тому
Hi, Thanks for another great video. Just two questions. 1 Why don't manufacturers use standard settings across every RCD, MCB, RCBO,SPD's etc. It would make life easier If the BS7671 made recomended seting mandatory for manufacturers.? 2 If you do not reccomend the use of the torque screwdriver being used as a conventional screwdriver, Why do they supply them with conventional bits?
@efixx 2 роки тому
Hi Bill, 1 - manufacturers use different layouts and screw sizes and terminals- hence different torque settings. 2- You still need the correct bit to apply the final torque to the screws. The bits here are interchangeable between screwdrivers and the torque setting screwdriver.
@asp217 2 роки тому
Please explain why more torque is required to loosen a screw. I have broken a few SL/PZ bits on Lewden boards and been in discussion with Tony Martin from Wiha regarding this. He mentioned that the driver is to be perpendicular to the screw (which I always do).
@efixx 2 роки тому
Generally less torque is required to loosen a screw compared to tightening. It’s a bit like pushing a car up a hill. Bits often snap (particularly slotted pozi) due to to quality of the screws - we’ll do a video about this.

True I had the draper one and it was ok, draper could have used better colours, always looked a bit fisher price to me, I got rid of it and got the wiha, only because I had a speede and a multi bit driver all of which took the vario bits, so made sense to switch

@seandempsey7351 2 роки тому
I completed Joe’s CPD on torque screwdriver and torque settings , i now have a better understanding of the impedance of them and as such my opinion has changed a bit , but I still disagree with you saying the required torque settings or the manufacturers required torque settings , in BS7671 it states two key words ,1) good workmanship and manufacturers instructions, it does not state required or manufacturers requirement at any point , it is simply a recommendation. I am now of the opinion that if you have a torque screwdriver then use it if you don’t have one then get one and use it. It’s no hardship , so yes I am happy to say I have one now and I do use it when needed.👍

Watch out for the range. The one in the video starts at 1 Nm which is already too high for some screw terminals. 2.5mm spacing ones are around 0.4Nm torque

That check box should have been made as a go/no-go box to make it truly useful and worth the money: At a fixed 2.8Nm it only tells you your driver is working on that sweet spot. Instead have a low and high setting (1.5 & 3.2 for instance) and it shows that the driver is correct across a _range_ not coincidentally correct at only one value (2.8=2.8 but 2.6=2.7, 2.4=2.6, etc.)

@G1ZQCArtwork 7 місяців тому
55 years, never used one, never will. You can "feel" when there is enough compression under the screws. I worry that the new generation of fitters will rely on these tools, only to find out later the wires have burned due to not being tight enough. On the other hand, only a fool would over tighten past the feel level. Call me old School, but I have NEVER had a fail using the old trusted method of feel, and instinct.

@Marcel_Germann 2 роки тому
@@acelectricalsecurity If you change your wheels you should tighten the bolts to the specified torque. And you should repeat that tightening process a second time after driving between 50 and 100km with the vehicle. And when replacing a board you actually tighten so many screws, to check the others isn't that big of a deal. And you personally can ensure that every connection was fine when you installed the board.
@acelectricalsecurity 2 роки тому
@@Marcel_Germann that's not really my point, my point is, if the bolts are correctly tightened then there's no need for anyone to touch them, and yes I know it's a few bolts and we all do them, but really we don't need to, I knew the transportation thing would be mentioned, that's why I pointed out a vehicle as an example, and take the wheel thing out the equation, every bolt or nut on a vehicle will have a torque setting which nobody checks on a daily basis before they jump in and drive off.

@arcadia1701e 2 роки тому
This bugs me. You harp on about following torque settings as per manufacture. Yet everything you did invalidates those torques. You are doubling over wires, the manufacturer tells you not too. Those ratings are for one single conductor stripped to the correct length and inserted. NOT a doubled over wire....
@efixx 2 роки тому
Doubled over wires do not cause any issue with the torque settings.
@alancooper7018 2 роки тому
I will say again, are we asking the wrong question, should we be asking are the manufacturers torque settings too well defined! A range of tightnesses would be adequate for a particular application! Where is the science that shows a particular torque setting for a particular application is correct! How much research are manufacturers conducting to justify their torque setting specifications!
