PM panels ( Double lugs with wire's stacked )

[Davebones]

We had some new switchgear installed in the last year or so . Notice that the manufactures of electrical equipment in order to reduce their " Foot Print " are making things smaller . A lot of the bigger breakers have the double lugs . You have to first tighten the bottom wire before you can install the wire on top . This is on parallel feeds . Used to be we would re-check the torque on a lug when doing a PM . Now to check the torque of the wire on bottom you would have to remove the wire on top . This is some good size wire so it's not that simple to do . Just wondering what other people are doing ...

We are seeing much less re-torque, but more IR scanning. If the IR shows a problem, then re-torque.

I have been taught that you never re-torque a wire connector where the bolt or screw that you are re-torquing is directly applying pressure to the conductor.

So if you find the connector to be loose you cut half an inch off the wire and re-install?
Makes some sense.

That is exactly what I was taught to do.
