Mixing wiring and outlet wire gauge .
Asked Feb 4, 2007, 12:53 PM
If I have a 15 amp circuit, and 14 gauge wire, why can't I install a 20-amp outlet? If a 20-amp device is plugged into the outlet, won't the circuit trip, preventing overload? Also, 20-amp outlets and 15-amp outlets appear to have the same connection for devices (two prongs and a ground hole), yet on this blog I think I am reading contrary information (I thought I read that a 15-amp outlet is constructed in such a way as to avoid having a 20-amp device plug into it - am I missing something? Thanks for your help (whomever is kind enough to reply)
