Breaker on #6 copper

I am putting in a subpanel for my workshop. I need another 240v line, so I

time, but that boat has sailed.
I am running #6 copper. As I read it, it is good for 55a, and since there
is no 55a breaker, I can use a 60a. Is that correct?
Yes, it is correct.
I did the same thing, ran a 60a circuit to my garage, and I regret to
this day that I did not make it a 100A circuit.
Spend a few more bucks and get a 100A circuit. You can then buy some
large equipment (welding, plasma cutters) and run them inexpensively.

On the other hand; the most I will ever ever use at one time is a bandsaw
and DC, which draw 27a together (which is why I need another 240v). I
happen to have a 30a breaker. Any reason not to just use that? It is over
the 80% rule, but I presume that applies to the wire rather than to the
breaker. If it trips, I can always replace it.
The #6 was only a few dollars more than the #8; so what the heck...
