That sucks....Each different brand could have a different torque setting
Why? Because you have to read some info?That sucks....
Yeah, I cant read....Why? Because you have to read some info?
You have got to be kidding! Its a schneider that I have bought this morning! £75 quid!! I can feel a credit back coming on..Just becareful buying a Torque screwdriver... Not all brands (Such as schneider) cover the full range of torque settings required by manufactures.

It's win/win mate. You don't have to learn to read and she learns about what you do for a living.Good thinkin batman! Cheers for the advice.
She already think she knows everything about being a sparky! I've yet to break it to her that RCD doesn't really stand for REALLY CLEVER DEVICE though!It's win/win mate. You don't have to learn to read and she learns about what you do for a living.

Find yourself an old-school engineer to teach you how to use & look after your screwdrivers & give him your £75.
I still have the set I made when I was an apprentice and they're still in good order and YES they DO get used!!
since when?Difference being Torque screwdrivers/ torque setting screws etc is now regulations.
NICEIC ask to see your torque screwdriver during inspection. I could rub some mud on it and make it looked used. A strong wrist and experience is all you need to do up an MCB, luckily I have both (No jokes about strong wrists please)Difference being Torque screwdrivers/ torque setting screws etc is now regulations.
since when?
Regulation 134.1.1 of BS 7671:2008 states:
Good workmanship by competent persons or persons under their supervision and proper materials shall be used in the erection of the electrical installation. Electrical equipment shall be installed in accordance with the instructions provided by the manufacturer on the equipment.
Difference being Torque screwdrivers/ torque setting screws etc is now regulations.
Regulation
So reading the manufacturers data/instruction they'll tell you to torque set it to X amount.

As in Competent person becomes skilled person. What will this person be in the 18th edition? A master craftsman, perhaps godlike in the 19th?Except where manufacturers instructions are not relevant or improper to the correct and safe installation of equipment, which I have come across many times. And I believe the wording of this reg has changed in the BYB anyway.

I suggest you buy well known brands which are CE marked and checked and not skimp out on poor products that'll have poor connection/terminations.

I keep coming across CU's where the standard is well below par, you need muscles like 'Garth' to get the screws in the neutral and earth bars to tighten. The builder keeps coming back with units from the 'sheds' which I now point blank refuse to fit. yes they are cheaper, but they are also crap and in my opinion dangerous.
So going back to the regulation. They( the manufacturer) has stated in their instructions/data a recommended Torque which as yourself has just confirmed and so not following that recommendation which they have stated is not following the instructions which is written in black and white on the data sheet is technically breaking a "regulation." Like the whole IEE wiring regulations, it's not law to follow them but against the law if you don't. Some questions are better off not asked/answered, but that's what they'll say if (Unfortunately and hope it never does) it went to court. These days it's all about covering your backside in our world and pass the blame back to the manufacturer.
the new regs say to take into account.I was at a NAPIT seminar this evening, a chap from the IET was also there to enlighten us and this matter was discussed.
It would appear in the eyes of NAPIT and the IET that the regulation stating manufacturers instructions must be followed does in fact require the use of a torque driver on not only your cable terminations but the checking of factory terminations as well. I m pretty sure that not all manufacturers instructions include torque settings, for example the Cheaper brands like CPN and the God awful CHINT boards (I do plan on verifying this).
As is often the case this is a regulation written for an ideal word and IMO leaves the electrician exposed to potential prosecution. But maybe I'm just being synical.
As it happens I do own a torque driver and use it whenever I discover manufacturers indicated settings, for example the Schneider (Merlin Gerin) breakers and boards have the NM requirement printed on them. I feel that if things are moving in the direction of electricians being required to install to precise torque settings all manufacturers should display there torque settings on the breakers themselves not buried in a leaflet or in some cases listed on a website.

i took the recommend nm into acount your honor but the cables were still loose so i tightened them up properly lol
im not buying the guidance notes till i either go self employed or the 18th comes outHa ha! Yes im with you there!
I have not read the reg in Am 3 yet as im still saving my pennnies to pay for yet another set of Regs books ��

I wouldn't either seeing as they can't be bothered to print them correctly.
I assume they were reffering to the ammended regulation
From the IET website, although I do not have the yellow book to verify that this is the exact wording that made it into AMD3.
Regulation 134.1.1 has been changed from:
"Good workmanship by competent persons or persons under their supervision and proper materials shall be used in the erection of the electrical installation. Electrical equipment shall be installed in accordance with the instructions provided by the manufacturer of the equipment."
to:
"Good workmanship by skilled (electrically) or instructed (electrically) persons and proper materials shall be used in the erection of the electrical installation. The installation of electrical equipment shall take account of manufacturers’ instructions."
thats exactly the same as in my bybLooks like they have managed to make it into even more of a grey area!
