On occasions where I upsize the homerun for distance I clearly label in sharpie what amperage to breaker it at.
"15 amps Only" for instance.
If the circuit has any 14 in it I don't want someone coming along behind me and thinking "This should have a 20 on it."

It seems Wire_twister's inspector is telling him he HAS to install 14AWG switch legs in his 20A circuit.
?????????
Why? I wonder what he's thinking.
