I'm adding an exhaust fan to my bathroom, as it's an old 1880s home that never had one. At first there was a 15 amp breaker using 14/2 cable feeding the lights and the outlets in the bathroom. I decided that with adding the exhaust fan though only being a few amp draw, it would be best to upgrade to 20 amp breaker and 12/2 wiring.
The outlets are 20 amp outlets. However, the 3 switches are all 15 amp. Is that ok? Two switches are toggle switches that work two different lights, and the 3rd switch is a timer switch that will run only the exhaust fan with light. So obviously none of the lights will pull more than 15 amps, but should I be concerned about the exhaust fan motor malfunctioning and drawing more amps than usual?
