Mixed wire gauges

I'm nearing completion of my basement wiring. I've only got wiring to run for the last light of 15A lighting run and the last receptacle on a 15A GFCI receptacle circuit. I've run out of 14/2 cable but I have enough 12/2 to finish the job.

I understand that 12 gauge is fine with a 15A circuit, but will my inspector likely have a problem with the mixed gauges?

If you let the inspector know about mixed wires and as long you have legit 15 amp breaker then you will have no issue with it.

I done that all the time with larger conductors as well { you should see me what I do with parking lot luminaries }

Merci,Marc

I was in that exact same situation when I built my man cave. I had spent a couple of thousand and figured that another $50 to do the job properly was within the budget.

Just out of curiosity, why did you run a 14/2 15a recep circuit? 12/2 20a would serve you better.

Because 14 ga wire is easier to work with. The benefits of running #12 is only a negligible increase in capacity. At least that would be my reasons.

All my new receptacle circuits are 20A. This last one is relocating a receptacle that is on an existing circuit in the unfinished side. It's already there, but is now in an inconvenient place.
