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?
Correct; this is specifically permitted under Article 240.4(B).
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,
Remember that the "80% rule" applies only to circuits serving a continuous
load, which is defined as "a load where the maximum current is expected to
continue for three hours or more." [2005 NEC, Article 100]
