I just finished installing seven LED recessed lights in my master bedroom. I had to fish wiring through the ceiling and through the wall to an existing switch. I'm changing the one gang switch box to a two gang switch box. I got everything put in and as I prepared to wire the lights in, realized I had run 14 gauge wire, while the existing circuit was 12 gauge, because it has a 20 amp breaker. This circuit is the LED lights I just installed, a ceiling fan with LED light, and ~5 outlets in the master bedroom. The largest load I would ever put on this circuit is a vacuum cleaner.
- swap out the 20 amp breaker with a 15 amp breaker and make a note on the panel that there is 14 gauge wire, or
- bite the bullet and rewire with 12 gauge?
I'm obviously tempted to throw in a 15 amp breaker, but want to make sure I'm not missing something here.
