I was always taught that the tighter you make a termination the better.

I have split neutral bars like zippers from tightening. I have stripped out 600KCMIL split bolts from tightening with 2- 24" pipe wrenches.

I have always done this in the belief that I was doing a good job.

But now I use a torque wrench and it always seems loose to me.

I thought the resistance falls as the connections get tighter.

And if not, what happens when I use a hydraulic crimper, that is certainly very tight.

Can anyone explain what happens when you over torque?
