Re: Smaller size wire on 20A circuit for dedicated purpose? It is perfectly acceptable to have a branch segment to the light above the junction box/point 14 awg. For the length that wire is, say 6-8 feet you could run 40 amps on it and still be within the 3% voltage drop rule. Perfectly safe and code complaint to my NEC knowledge.
I'm sure Nunya will set us all right in short order  |

kudos:4 | Duno if its compliant, but if the junction box is fully accessible, you could fuse the 14ga chunk of wire with a 10-15a fuse contained within the junction box. Would prob have to be a 4x4 box tho..
thats the plumbers point of view.. hehh

It you go the 4" box route, simply install 2 GFI outlet breakers. One would be a 20A that would be feed from the 12AWG wire and then feed any other bathroom 20A outlets ; and then a second 15A that would be fed from the 20AWG wire that would feed the 14AWG for the light.

wouldn't it be easier to fish in new wire?

wouldn't it be easier to fish in new wire? From the OP's initial problem statement: "I am having a major issue running a new wire for the lights above the sink, there is a big AC duct above which blocks access."

Can't, there are studs and joists blocking, only way is to come from above but that is blocked. |

Post a pic. I already closed the ceiling and floor. Side would involve a 90 degree turn behind studs.
I'll just use the 15A circuit for those lights. |
