Desired set-up:

Light fixture outside front door is on Breaker 1 and controlled by a
single switch inside the front door.

Light fixture over garage door is on Breaker 2 and controlled by two 3-
way switches - one in the garage and one inside the front door.

Can the single switch and a 3 way be installed in the same box even
though they are on different circuits?

Do the breakers have to be ganged if this done?

Thanks!
After reading the many responses, one
thing came to my mind and I am not sure
how the code handles it. I know if you
have 2 circuits in a "raceway" of
different sizes (different breaker
amperage), I seem to remember that all
have to be treated as the higher
amperage. Does that apply here?
Anyway, might be a mute point if they
are both 15 amps or both 20 amps. Any
code experts?
