How to Set Up and Use a Torque Screwdriver for all the Connections in a Consumer Unit (Fuse Box)
Student training aid for how to set up and use an electricians torque screwdriver to correctly reconnect conductors into a consumer unit (fuse board or fuse box). Video includes a full demonstration of how to set up a Wiha torque screwdriver correctly and using a slotted pozi head number 1 and number 2. The demonstration includes the tightening of all connections within a domestic consumers unit (fuse box). It is important to return all the screws in a consumer unit to the manufactures correct torque setting.

Lads the videos are awesome as always bought this kit myself. Was using the wera torx driver but found out there range of values from 0.3 to 3.5nm is split across 3 separate drivers, the robbers, the wiha will do 0.8 to 5nm singly and also a far better tool to use and feel. Only caveat is adjusting the torque setting is fiddly compared to the wera. Two similar priced tools but the wiha tops off. Just thought I'd throw my 10pence in for the viewers. Steveo sparks.
Just had a look at consumer unit world And it say for wylex CU wylex RCBO torque setting is 2.8nm and main switch/RCD is 3.2nm So if I am not mistaken the CU and breakers as well as the mains switch in your video are wylex so joe has under tightened the terminals as he only set the screwdriver to 2.3 nm . Fantastic video guy’s as always .👍👍👍❤️
Excellent demo. The Armeg set is also excellent.
Another lovely well explained video lads 👍
Another brilliant video Gaz guys. Love the look of these
Thanks as always Gaz 👍
Nice one chaps, very interesting and informative. 👍
Great job. I have 3 of these torques screwdrivers
Always amazing videos and always some help. Got a prep day for college on March 2nd Feb, and we will be asked to wire a 1 way lighting circuit. Any chance you could do an informative video and what we should do?
I am a culprit of using the @AVE method of saying ...'click' as the screwdriver turns. Need to invest in one of these as have had to return after a couple of weeks to ensure nothing is lose.
DIM Tips I think the AVE method would be better, this is a waste of money it doesn't have all the commonly used torque settings (so doing 1.7 could be 1.5 who knows) and needs calibrating realistically every time it's used if it's dropped banged etc it could be knocked out of calibration.
When storing the torque screwdriver do you need to release the tension on it first? i.e turn it all the way back to 0
its not required with the wiha
Hi, Is the torque settinhg the same for all circuit breakers.or neutral and cpc leads? or does the torque setting used ony apply to the CU wich you used the driver on?
is it OK to undo the terminals using the Torque screwdriver ? when i was at college doing training, albeit motor vehicle, we was taught and told you should not use the torque wrench or torque screwdriver for removal, only for tightening ? so was that just rubbish, or should you really not use a torque device for removal ? just curious that is all.
Do you guys not use affiliate links to products? Good for you and saves me time googling how much this kit is. I already have one but I’m just curious lol. Love the slotted pozzi driver.
Hi. Sorry about that. We don’t have any sponsors so we can use a wide range of kit from different manufacturers. We are just a couple of college tutors but thanks for commenting and watching Gaz 👍.
GSH Electrical sponsors are a bit different. Check out Amazon affiliate program, let’s you link to the products you are discussing and make a little commission in the process. You can say what you like/dislike about the product at the end if you want to, but not absolutely necessary. As industry professionals, your opinions are invaluable, as these videos prove.
I work in metering for British gas and we have just got the wiha torque screwdriver, it's set at 2.8 NM and can't be adjusted by us, we use it on cutout, meter, henley/Lucy blocks and isolator screws, we need it calibrated every so often, that's not been established yet, is that one you use need calibration?
Hi. From memory this type of torque screwdriver requires calibration every 5000 turns (start counting) or every year. Thanks for commenting and watching Gaz 👍
GSH Electrical where would you even get a screwdriver calibrated ?
Is this an installation certification requirement yet or just good practice? Great video BTW.
Yes, if you want to cover your behind in case a fire breaks out later.
👍🏻
had the manufacturers of consumer units made their insulated boards to the British standard, rather than just putting a sticker on it saying it complied with the British standard, i doubt if we would have metal boards or the topic of using torque screwdrivers. As usual its cheaper and easier to deal with the possible symptoms rather than the cause, why there has not been a recall on them i dont know, just been swept under the carpet.
They're called a ZENON #1 & 2 DRIVER TIPS or Terminal Block Driver Bits
👍👍
Do the connections at outlets need to be treated the same?
@@GSHElectrical I actually was thinking the cooker would need that, really good to know. Thanks for the reply.
I’ve got exactly the same Wiha torque set in this video and mine also has a range of 0.8nm - 5.0nm. However when I adjust to its minimum value I can’t go below 2.4nm?? Am I doing something wrong or could I have a faulty set?
Possible faulty 👍🏻
@@GSHElectrical Many thanks for such a quick reply. Always appreciate your videos and help. 👍🏻
how would anyoine check that these terminals have been screwed up to the right torque?
You can't, unless you do it your Self
i got a torque screwdriver built in my arm heh ;)
Joe when someone over tighten and marked the cable inside (squeezed ) and then you loosing little and try to tighten on right torque , because of mark on cable you need to over torque little What you say it’s right on new connection on new pease of cable
Just what I thought watching this video. Theoretically, doing like as shown in this video, some wire may be left loose and cause arcing. Just depends how over-tightened/squashed the wire was originally.
Would this in time be used on sockets to?
Surprised no one made a joke about a number 1 or a number 2! Perhaps it's just my toilet humour?! 😃
After making comment on your other torquing video. This is how to make sure your torques calibration is not drifting and invalidating your testing. @gAuQ

Sorry sorry sorry, but Gaz you continue to use the therm requirement . It is NOT a requirement to tighten the screws on a CU to a torque setting it is how ever a recommendation . Can you tell me as to why the there is no mention of the electrical industry on the packaging of theses thing’s but they they do reference the motor industry? BS 7671 DOSE NOT say anything about the use of torque screwdrivers or torque settings, it only states the equipment SOULD be installed according to the manufacturers instructions not must or that it is a requirement.
Regulation 134.1 is a great starting point to add to your own knowledge…
Sorry for the quitesisum, But tightening the terminal screws on a cu or mcb/tcd is only a manufacturers recommendation NOT a requirement, that's why different manufacturers have different settings for torque, this is just forcing us sparks to buy tools we don't need The average human can genorate 67.2nm of torque with just the wist, if you can't tighten down the screws on the cu then maybe you should jack it in and get a job in McDonald's. The same can be said for the use of those fancy MFT'S THE TESTERS FROM THE 50s/60s and on words are still complyant and can be used so long as they are kept calibrated , I have been using my late bothers Robin MFT since the late 80s with out any problems, and you can buy them second hand for as little as £50 send them away for calibration and your good to go. Again sorry for the quitesisum and I don't mean any disrespect to you or anyone else. You're videos are great Keep them coming
and return the screwdriver torque back to zero
two wires on same ... no way
Ring main, same circuit.
thats the way we do most sockets circuits in UK
yes, as usual they solved a problem (shortage of copper after the war) by creating another problem. typical british.
