Actually, we have two issues here, both with different answers.
DDuBose said " ... over two branch circuits in one breaker." There is nothing inherently wrong with two, or three, or however many branch circuits you want on a circuit breaker.
Blaine correctly identified the other issue "Are you talking about a double tap?" Multiple taps (I use multiple taps instead of double taps because that also includes three or more in the 'more than one') are not allowed ... unless the terminal is approved for it. Basically, then, if it is not a Square D breaker with the twin captive plate under the screw head, only one conductor is allowed.
So it becomes HOW the conductor(s) are terminated, not HOW MANY are on the breaker.
How do you solve this on other breakers? By removing the two (or three or more) conductors from the breaker, connecting them to another conductor with a wire nut (a multi-wire connector) and installing the new, single, conductor in the one-conductor-terminal of the breaker.
You now have two (or more) branches to the branch circuit, both of which must have properly sized overcurrent protection. I.e., you could have three 30 amps circuits on a single 30 amp breaker, and each would be protected properly. The circuit rating (for all three combined) would also be 30 amps, because that is the rating of the overcurrent protection.
One exception, is, of course, FPE, Those thingys don't trip anyway (at least not very often), so you have no (reliable) overcurrent protection, and your circuit is whatever you can put on it until the main transformer blows or the wires melt down. ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif)
Anyway, before I get to be a Deleted User here to, I'd better go.
