Torque settings - hmm

[Madocks]

Bought a torque driver today, any clue on recomended values for connector blocks, henleys, MCB ?

I imagine its cable size dependant? Anyone have a quick table i can print and laminate?

Please dont say manufacturer instructions! would be poop!

Ahh, but in the event of some misfortune, you'd need to say you tightened to the relevant manufacturer's instructions, not some other value you decided for yourself!

Unfortunately MIs are very variable (a bit like the torque settings).
Different items need different settings even if the items are from the same manufacturer.
Some items will break if you tighten them to the recommended torque!

This pdf that was available from the neweys website gives a (not quick) table of torque settings for a variety of manufacturers and parts but it could be out of date by now so do check. All parts that require torque settings should have the setting in the instructions (you know the annoying bit of paper that gets in the way of installing things!)

Tighten, wiggle, and tighten

How much you use it is up to you, but I always recall a tale some years ago from my electrical course tutor about a court case after a fire, asking to check the electricians tools, and finding no torque driver amongst them, so they could not have installed the equipment to MIs.

He hasn't got that problem now! They will find a torque screwdriver!
Possibly very cleanly kept and looked after and not scratched at all!

Only comes out of its case on annual inspection date ?

One of our customers specified 10Nm on their connections, after a few fires they dropped this to 4.8Nm.

never been asked about one of them.

Having to possess a torque screwdriver in our feeble occupation

I suppose these metal consumer units are going to end up becoming flameproof equipment,at least the tool would then have a useful purpose

It seems to me health and safety is not the only place where the inmates have run riot

Every year the assessor goes over all the sample cu terminals and checks them for tightness by the arm & wrist method.
