two pole breaker terminal size

I've seen on a lot of terminals that the maximum is just barely doable. If #4, they mean #4 compacted tight, no loose strand from a bend, or a #4 solid, which exists only as a ground for the most part. Very irritating.

Is #6 60 amp Rated? If you protect a wire at 60 amps why would need a wire larger than #6

OP's situation is one thing, but breaker manufacturers often have lugs that accept at least a couple sizes larger then the usual minimum conductor size needed because people do run into needing to make ampacity adjustments or compensate for voltage drop.

The info is on the breaker label.




ETA: Siemns data sheet, second to last page-lug info. https://s3.amazonaws.com/cesco-content/unilog/Batch4/783643/101285-AttachmentURL.pdf
Interesting.... data sheet says #8-2/0, breaker label says 6-2/0.

Info on breaker label - in a picture on HD site - they happen to have one with "60" on the handle - but wouldn't surprise me one bit to see some other number on the handle as the image for that product. I still trust data directly from manufacturer more then data obtained from HD.

I don't use Siemens often enough to know off top of my head what lug data is on this breaker. I do know I have hooked up many motors or air conditioning equipment with Square D 60 amp breakers that only needed 8 AWG or even 10 AWG conductors.
