Torque settings

Hi all,


Obviously, where available we use manufacturer's torque settings for connections. But where do they get them from?


I ask this not least because it's not always easy to obtain, at least in a timely fashion, but also because I appear to have conflicting instructions on some OEM'd equipment (comparing the original manufacturer with the wrapped supplier) or notably different settings when using the same lug onto a very similar terminal bar from a different supplier. It would also be helpful to be able to sense-check the answers for misplaced decimal points.

  • The comment about the zinc plated steel bolts brings to mind an accident I've had once or twice... you go round doing the 'check all connections INCLUDING factory ones' routine before closing the CU cover on a new install or indeed any job... get used to the way the torque feels... then proceed to tear off the head of a screw in the external Main Earth Terminal block, because they're still brass... D'OH!
