15 amp breaker

I cannot tell if the wire coming from a 15 amp breaker in my panel
is 12 g 0r 14 g.

I am installing recessed lights in my kitchen.

If it is 14 g, can I connect a 12 g wire to this 14 g wire?

Go to your local home improvement store and buy one foot of 14-gauge wire and one foot of 12-gauge wire. The cost is pennies. Compare those samples to what you have.

In most cities, you can connect 12-gauge wire to it whichever of the two sizes you have now. Of course, once you have the 12-gauge wire in your hand, it will be easy to tell what the existing stuff is. However, many people would suggest that it is bad form to connect 12-gauge to 14-gauge, since it may fool somebody later into thinking that all the wire on this circuit is 14 gauge.

John is absolutely correct. To make clear though, it is not a code violation to connect #12 wire to a #14 nor connect #12 wire to a 15A circuit breaker according to national codes, your local codes may differ, but probably not.
