Connecting 12 gauge and 14 gauge wire
Asked Sep 7, 2008, 11:45 AM
Is it ever acceptable to attach 14 gauge to 12 gauge wire? I have a remodel situation where I have a 20 amp/12 gauge wired circuit powering outlets only. I want to tap off the end-of-run outlet to power an electric-venting skylight. The skylight comes with 14/2 wire. Can I tap off the 20 amp circuit to run the skylight, which would require connecting 12 gauge and 14 gauge wire? I thought it might be okay since the skylight motor only draws 60W max and would never pull more anywhere close to 15 amps through the 14 gauge wire, but I still feel uncomfortable doing this.
