You hit the nail on the head. It's the breaker that matters. You don't want a 20a breaker on wire that's only good for 15 amps. The wire could potentially meltdown before the breaker would trip.
you are right but also wrong as is someone else above.

its the WIRE size AND breaker size that matter.

the breaker goes with the wire size. you can have a 15a brkr on 12ga wire.
you can NOT have a 20a brkr on 14ga wire

you CAN NOT (or should not) put a 20a OUTLET on 14ga wire with a 15 or 20a brkr
this case the outlet matches the wire size.


just remember, the breaker is there to protect the wiring, nothing else. the outlet limits you from connecting a single load that pulls more current than the WIRE can deliver.

I prefer to run 12g with 20a outlets as the outlets are a bit beefier.
not an electrician btw.
