To torque or not to torque that is z question

[Dustydazzler]

so I need to add 1 mcb to a rather old existing mem consumers unit

I have managed to source the mcb via ‘cough’ eBay ‘cough’

But it doesn’t have the manufacture spec installation instructions manual for correct torque

Should I..
A , contact mem helpline for further information
B , wing it and guess the required torque
C , just use a normal Phillips screwdriver and let my wrist do the torquing

Thought ?

Dear god kill me now.

BANG...........

I would go for option 'D'
This involves getting hold of a 1/2" drive ratchet with correct bit for the screw and also a 2 to 3 foot long length of scaffolding pole. Make sure that either the ratchet has a rubber handle or you are wearing a pair of rubber gloves though.

option E....... use a hammer.

I'd go for option F...…..get some cocky SCOUSE sod to do the tightening for me.

"C"

Tighten it until the plastic casing of the mcb goes crack.
Then go back onto eBay, buy another to replace the one you just broke and tighten this one up just a little less than the first.

but does a C curve MCB require a higher torque than a B curve. after all, it takes more electrons quicker to make it function,

Still going for the F curve...

Sorry wrong one

Meant to be this one

I find all this torque somewhat strange, we never had torque info' or tools pushed onto us back in the day, we just learnt what was about right and I have yet to return to any job because I under or over tightened a cable termination.
Is this just another money spinning exercise by the industry or do we really have masses of professionals making bad terminations?

I forgot option

D , use my 18v impact driver

There is some truth in your statement DW but far to controversial to post my reply
