As a licensed avionics engineer, I watch your videos with interest. In the aviation industry, where a torque loading is specified, it has always been a requirement that the torque wrench or screwdriver is within the calibration date AND checked for the specified torque loading using an Acratork rig (or equivalent) when securing the fastener. It makes sense for hard materials but when securing malleable materials, such as bare conductors, the torque figure might be "within specified limits" right up until the point where the material has all of its properties damaged to a critically dangerous point. It would be good to see if conductors are materially damaged from the lowest to highest specified torque loading figures specified.
Brought one of the wiha torque drivers as had the rest of the kit , use it every time on boards , come across no end of boards where it’s been over tightened and twisted the terminal out of place (prob by impact or battery driver )
I’m suprised to see that there isn’t already torque settings for sockets and switches, however I’ve just seen the new screwless sockets which could be the future. Exciting
It'll be interesting to see if manufacturers will require accessories to be done up to specific torque values. I suspect it will happen in time. We'll see!
I use one frequently, a whia one in fact. And just recently I torqued up a neutral bar on a brand new Hager board, (setting set to the exact setting as per MI’s, and it broke the bar in 2. And no, it wasn’t done up past torque to start with just nipped then torqued. Possibly just a faulty bar yes, but still, frustrating
Should we also use a torque screwdriver on terminals in all socket and lighting final circuits? Or can we use the "manufacturers instructions" clause to omit this?
I've managed to snap the end off a torque screwdriver blade tightening a crabtree Rcbo live/line terminal as I used one of the thinner blades because of the insulation stopping the end reaching the terminal screw as they are further in. Luckily local wholesalers just swapped it for a new blade
The problem is that some folk think "oh the driver has clicked, its torqued up". NO it fecking isn't! Give it a pull, 9/10 it will be loose. Torque it, leave it, tug it and repeat. Strands flatten out and become loose. Better option is to flatten strands out before putting in terminal. But what do I know, see present wife for further details
My biggest issue is I have a Draper brand torque screwdriver. I am working in a 630A 3 Phase Main cubical with Eaton MCCB's of various sizes which terminal is a Hexagonal screw to tighten the connections. Draper torque screwdriver set does not include a hexagonal attachment and having contacted Draper, they do not do a hexagonal attachment and gave me no solution to get the right torque setting. Do I really need to go out and buy another torque driver well over £100 or do I use my experience and tighten them by hand? This is the real world and manufacturers dont give a damn it seems.
To be fair, a torque screwdriver likely won't give you enough torque to tighten up an MCCB to manufacturers specifications. Most screwdrivers will give you 5nm tops and an MCCB will often be above that. You'd probably be better investing in a torque wrench if you do a lot of industrial work. Then you can buy any sort of generic attachment with a 1/2" drive to suit the breaker you're working on.
So realistically, if we don't use a torque screwdriver ( yes, I do, checked twice normally) and the manufacturer recommended its use, you should declare this in the departures from BS7671 in any cert you issue?? Or would that be too far?
Connections in a board should be torqued down at the point for where most circuits should experience the highest load, except for those circuits that supply an invididual piece of equipment for example. Not that almost all DIY'ers will care. So should say a cooker plate having a high powered single fixed load, with the power equal at both ends, have torque settings specificed by a manufacturer to prevent under/over tightening etc, as most people fall in the mantra of more torques = more betterer?
You raise an interesting point here, it'll be interesting to see if manufacturers start specifying torque values for accessories other than consumer units etc. We'll see!
What are the problems with over torquing? I've seen plenty of issues with under torqued connections over the years but if its done up firm are there any problems?
I hope we do not get to the point of needing to torque accessories in the future, not because I don't agree with the practice but I hope we see screw less terminals on all accessories in the near future negating the need to torque anything. I have no clue why we have not seen this change happen already in the main stream just as MF junction boxes with their relevant connectors seem to have been adopted by many. Also it has been shown screwed terminals can come come loose over time due to various factors where as many screw less alternatives do not exhibit the same behaviour. I wonder if we will ever see a totally screw less consumer unit in the future?
I’ve said about screwless accessories for years. It would work on socket outlets well allowing three cables for Spurs from a ring with 2.5-4.0mm cables. The problem I see is certain accessories like a three plate pendant with possibly no room to expand from. I know three plating at the light is kinda being phased out in new builds but still needed for retro fit and personally I like to see a permanent live at light and neutral at switches for smart. Isolators for cookers and showers would be great screwless as we see so many burnt out due to loose connections
Common variables, such as wire type (single strand or multi). Quality of wire.? (or the screws themselves). In the 55 or so years I have been tightening screws, so they don't get hot, or damage the wire, I have never used such a device. I would need to check tightness with a normal screwdriver afterwards, so what use would a torque driver be.?
@@efixx Indeed, but, what if the calibration was way out, and you didn't realise.? Do you just blindly carry on and not go back to the previous installation, where the torque settings are now wrong, or do you use years of experience to tighten them properly with a standard driver in the first place.?
A torque screwdriver doesn't do the work for you. Once you've getting to the point where it's going to release, it feels identical to doing it with a fixed screwdriver. I suppose the concern is new electricians who have zero clue what the required torque feels like and blindly follow what their equipment says without also applying a little common sense. Torque screwdrivers would absolutely not be the first place that happens though!
You could argue that "take account of" doesn't mean the same as "follow to the absolute letter" . Oxford defines it a "consider (something) along with other factors before reaching a decision." and merriam-webster "to give attention or consideration to (something)"
So let's imagine something goes wrong and you have a warranty claim or worse a fire - how does the argument for ignoring the manufacturer's instructions stack up?
@@efixx Read it again "taking account of" doesn't mean ignoring. If the regulations mean "follow the manufacturers instructions to the letter" then they need to say that but they don't. But also there's the practical aspect of how would anyone ever prove the screws weren't done up to the correct torque and hasn't been interfered with since?
@@mfx1 Instructions say tighten cover screws to 1.7nM to ensure a waterproof seal, in your own judgement, decide not to follow this and over tighten the seal. Three months later product fails due to moisture ingress through the over-tightened seal. Who's liable for the problem? Some instructions are black and white.
Great video as always Joe.

Not really, setting terminals to the correct torque has been around for ages in industrial installations, particularly with big MCCBs. It's becoming increasingly important in domestic consumer units now.
All commerical and industrial sites have preventive maintenance schedules. And apart of the schedule electrical integrity inspections, with visual checks, torque/tightness checks (should tightened to ~80% of torque rating so you do not fatigue with over tightening) and current draw measurements, voltage imbalances, and maybe dialetric integrity tests. Nothing is set it and forget it.

They can give a false sense of security. Having your torque screwdriver click and just assuming all is good is worse practice than using a fixed screwdriver and giving it all a good check over to ensure tightness. Ideally you'd probably use both. Fixed driver to get everything to a "it's not loose" torque and allow the conductors to do their initial movement, then go back over and torque everything up to the required spec. I imagine that if all electricians suddenly switched to torque drivers tomorrow there would be more loose connections than there are today.
My two pennies worth, if an accident happens and you end up in court being prosecuted , and you were asked did you torque up the screws in the CU , according to the manufacturer instructions , pulling out you torque screwdriver in court can save your bacon. .

In my opinion the torque settings applied should be evidenced on the relevant electrical certificate as prove of compliance with manufacturers instructions. Just owning the tool is not enough.
Just trying to make the job more difficult with all this shit so all the consumer units that haven’t been done are all dangerous I don’t think so More and more regulations if it’s not broke don’t fix it
