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!

Is there enough room in the box? If so, why not share a box? Just
don't mix the wires up if you have to move them.
