I would do it over with 12 gauge wire. If you have some kind of short,
the breaker won't shut off without 20 amps of current, overloading the wire
and possibly setting you up for a fire. Or maybe liability to the future,
long after you sell the place. Part of the satisfaction of doing a job is
doing it correctly, and it will sit with you for years if you made a
mistake. You never know what the future owner will do to that line distal to
the device. I think it is probably against code, the small load
notwithstanding. Alternatively you could change the breaker to a 15 amp
device, if the line draw isn't too high.

I am planning to have an isolated ceiling fan switch as an end run of a 20
amp circuit.

I ran 14-2 wire from the fan...to the new switch...to the receptacle that
was 15 amp. As I was preparing to tie this all together I noticed that the
receptacle was fed by 12-2 wire and...sure enough there is a 20 amp
breaker.


Since the fan (no lights) hardly pulls any amperage it seems like I should
be able to run the 14-2 anyway.

Thoughts?
