I have the 67015 electric fan which I purchased and installed several years ago. I am cleaning up/replacing some wiring and noticed the (green) signal wire and (black) ground wire are (marked) 14awg while the (red) power wire appears to be 10awg (not marked); is this correct? Being that the fan draws 13.9amps 14awg wire should be sufficient for the power wire, yes? I cannot remember if the fan came with a heavier 10awg power wire or if for some reason I used some 10awg I had laying around. Thoughts?
