Inspected new construction home yesterday. At the bottom exterior of the service panel is a photo cell that controls an exterior light at the garage door. The wires coming from the photo cell go on to a 15 amp breaker, neutral bus and ground bus and are 16 guage wire. It appears that the (spliced) wire from photo cell goes out to the light and is also a 16 guage wire. Does this pose a problem because of the 14 guage minmum size rule or is there some exception for photo cells that I am not aware of?

Thanks,

Eric
