torque requirements of MCB terminals

[spud1]

Does anyone know the general torque requirements of MCB terminals?
Just bought myself a new torque screwdriver set and ought to know what I should be setting it to!

 

[trev]

Each different brand could have a different torque setting

The requirements, if any, will be included in the literature associated with the equipment.

Because he's about to learn the futility of buying a Torque Screwdriver for domestic MCB's with their pi$$y slack poorly formed terminal screws and badly tapped holes in the busbars.

Until the manufacturers seriously address that little issue you'll never get the terminals to stay tight for any length of time!

If you don't understand what I'm banging on about take a look at your modern terminals and compare them with the old ones that you're all so keen to chuck away. Two properly formed screws per terminal for a start!!

It's win/win mate. You don't have to learn to read and she learns about what you do for a living.

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!

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!!

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)

Regulation

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.

So reading the manufacturers data/instruction they'll tell you to torque set it to X amount.

Which regulation would that be then?

Some of these terminals are of such poor quality you hardly need a screwdriver at all - you can almost push them in with your thumb just like a press stud!
