Jeff,

It's my understanding that the Square D QO breakers are OK with two wires. Most
other brands I've used are not.

Have you discussed this with your inspector? It seems unlikely he has never seen
these breakers used this way before. In my experience, in VT/NH, it is a very
common application, and one of the advantages to using Square D breakers. Most
electricians in this area are aware of this. It is also common to see other
brands of breakers misused in this way. A generally acceptable alternative is to
splice the two wires to a third wire, in the breaker panel, using a wirenut. The
other end of this third wire, of course, goes to the breaker terminal. It is a
good idea to label the wires to distinquish them.

Of course, an inspector has the authority to call it any way he or she likes.
Most, however, are quite open to diplomatic negotiation on differences of code
interpretation, UL listing, etc.

Hope this helps.
