I have an existing 20 amp grounded circuit in my garage. It is wired with 12 gauge as it should be. I tapped into it and ran UF-B buriable cable through the proper conduit out to a lawn light that has merely a 15 amp bulb and to a small gate opener that only draws about 2.5 amps when it runs a few times a day for 30 seconds. They are about 40 ft away. I used 14 gauge wire. Since the the light and opener are not drawing much amperage will this be ok even though technically I should have used 12 gauge?
