Some people think GFCIs are also overcurrent devices but they're not, they wouldn't know or care if you passed 30A through. In fact 15A GFCIs are rated for 20A passthrough. You cannot buy a GFCI+receptacle that is only 15A. | |

| Feb 14, 2018 at 2:25 | comment | added | Harper - Reinstate Monica | Your common sense has correctly captured the concept that breakers protect wires and devices. Indeed, given a partial short, the 14AWG wire would overheat faster than the breaker expects, so the (delayed) thermal-trip protections in the breaker would trip too late. | |
