Nothing wrong with that. Thats experience and knowledgei run them down with a cheap 4V battery driver with torque settings, then hand tighten to correct tightness.

I suppose if you have an understanding of power tools then it’s fine one of my best mates does it with impact and I cringe every time I see/hear him at the consumer but to be fair he understands the torque it’s the ones who don’t have knowledge/experience that cause the problems anyhow I don’t like power tools at consumer
Doesn’t matter shudn be using them unless like @telectrix just posted then that’s the exception “HAND TOOLS ONLY”The drill/driver is used in that video is not an impact driver and can be set to exceptionally low torques. I've no idea what it was set at and whether or not those terminals were over/under tightened, but it's worth noting that they are very different tools.

what do you use mate? Drill/driver is it?The drill/driver is used in that video is not an impact driver and can be set to exceptionally low torques.

??Drill drivers can be set to exceptionally low torques - often so low that it wouldn't be considered much more than hand tight.
Having said that, I just looked at the video again and note that it is indeed an impact driver
I'll be honest if I've got a board full I'll wizz all the terminals fully open with the driver and tighten them back up just tight enough to hold then run down the lot with the torque driver.If people are using 18v impact drivers to tighten down terminal screws something went wrong with the trade...
Ok so you’re under the category of experienced but I’m sure you agree with the fact that it’s more sensible to hand tighten terminations so you can feel the tensionI'll be honest if I've got a board full I'll wizz all the terminals fully open with the driver and tighten them back up just tight enough to hold then run down the lot with the torque driver.
If you use an impact enough then you can be quite gentle with it.
Never rounded a screw yet
Good man stick to the hand tools once mounted ?I don't regularly fit consumer units - in fact I've fitted a grand total of one and the use of power tools was limited to mounting it.
There's a time and a place, if its an obsolete MCCB it'll be hand tools only, if its a board change and mistakes can rectified the returns outweigh the risk.Ok so you’re under the category of experienced but I’m sure you agree with the fact that it’s more sensible to hand tighten terminations so you can feel the tension
Normally it’s 1.7N isn’t it? Only 2.1 or higher for main switch you don’t need torque settings to know the correct torque I don’t think aslong as you understand the recommendationsI don't know how these manufacturers calibrate their torque screwdrivers, but mine was so far out it could not be tightened to 2.1N required by Hager without bending the Din rail the RCBO was fixed too, anyone want to buy a full set of Armeg drivers?
Difficult area but again like I said it all boils down to experience and knowledgeNormally it’s 1.7N isn’t it? Only 2.1 or higher for main switch you don’t need torque settings to know the correct torque I don’t think aslong as you understand the recommendations
It would depend on the type of threadlock.What does grind my gears is certain manufacturers applying thread lock to terminal screws, not sure how that helps come EICR time.
It would depend on the type of threadlock.
Some is soft and easy to undo, only to stop gross loosening from vibration, etc. But some (e.g. "studlock") is like superglue and never expected to be undone without serious force!
If you do need to stop an adjuster from moving unintentionally and don't have anything special to hand you can use a dab of nail varnish, which you can get pretty much in any local chemist or supermarket.
In case there are any woke snowflakes reading this... I should add that mens tights would work just as well.It's a good excuse for why you're carrying nail varnish as well. I always carry women's tights as well in case my fan belt breaks.
So when you test N-E for a particular circuit you will have all the CPC's connected in the earth bar? What would be wrong with doing the IR testing of N-E without having the CPC's in the earth bar? Are you saying parallel paths could cause different results? Are we not testing that particular circuit, i.e that particular cable, which is why we put the test result in the little box related to that one circuit?You should connect the cpcs first.
There could be Parallel paths to earth. I’ve never know anyone to not IR test with everything connected to the METSo when you test N-E for a particular circuit you will have all the CPC's connected in the earth bar?

A lot of questions there!
The CPC of the circuit being tested is probably isolated from all the others CPCs and the Earth, so you would not see a leak from N to true Earth (e.g. a screw, etc, that is touching the N copper and in to plasterboard, etc) as it would not be guaranteed to complete the circuit from true Earth to CPC and back to your IR tester.What would be wrong with doing the IR testing of N-E without having the CPC's in the earth bar?
