I’ve got a torque driver, only gets used on boards though. I don’t go back and retighten with a regular screwdriver…. That’s just pointless.
I will, however, check every terminal in a board even if I’m just working on one circuit… although that only finds loose connections, not over-tightened ones.
Someone else on here has my ones twin.
It came with a #1 and a #2 +/- bit which I manage to break the tip off the smaller one on an RCBO at not very much N/m setting (warranty replacement, got both sizes in return)
Also the one I have doesn’t fit any other brand of driver bit. Just slightly too small.
And final gripe, the increments go up in .2 so 1.0, 1.2, 1.4 etc
When most published torque settings for MCBs and the like end in .5
In a response to some other comments….
“I’ve done loads of boards without a torque driver, and none have gone on fire”……
That you know of. Maybe further work has been done, which has been blamed.
“Always have what’s legally required. Down to you if you use it”
This is sadly true. How many instances of drive by EICRs have we seen where the £1000 MFT has never left its box.
