I'm thinking of getting a torque screwdriver but unsure if it's worth it. Is it a regulation now or just good practice now for connections to be torqued? If so is it just for CU's?
 
There is not a regulation, as far as I'm aware, that you have to use a torque driver to tighten terminals, but there is reg 134.1.1, .....good workmanship......take account of manufactures instructions, and as most CU manufacturers detail torque settings for MCB's etc, it something to consider.

I have one and use it on MCB's etc, but I also been known to use my wrist torque settings!

Issue with them, is they need annual calibration, and without the current manufacturers instructions, how do you know the settings for an older MCB etc?
 
So who does the calibration? Let's say your changing a CU or putting a new circuit in, do you think it's a necessary tool to have?

If you have spare cash, it could be useful. If you haven't, its a luxury. That said, if your CU has 'issues' 'cos you've overtightened it, you could be scrutinised 'cos you haven't a torque driver.

They'll be some old sweats along shortly, to shoot me down in flames :rolleyes:
 
That's my concern. Iv used one on a CU and I was a little surprised when it clicked to indicate it was tight enough. I just thought it highlighted how heavy handed I was
I started using mine regularly when a couple of MCB’s I was tightening split as I had over tightened.
 
bloody things . fit for limp wristed poouufs. if you can't tighten a screw down properly, maybe time for a career change to lawyer/accountant/politician/shelf stacker.
 
it's not about that telectrix, it's about wanting to provide a professional and safe service. No matter how good you think you are, you don't have a torque mechanism in your wrist and I bet you have over or under tightened a mcb before. No ones perfect but we can all try to be
