12/2 on 15 amp circuit

Hi Everybody!

I have a 3-way switch that controls a light; all of the current wiring is 14/2 (and 14/3 for the 3-way part).

I plan on replacing the single light with multiple recessed lighting cans... my question is:

Can I use 12/2 from the switch to the new lights even though the power source to the switch is 14 gauge wire?

Yes, but there is no advantage, and some definite drawbacks. It is more expensive and more difficult to work with. It will also reduce your wire fill capacity unnecessarily.

Unless you have some lying around already, I wouldn't.
