ya dude 14 gauge wire would be fine to wire up the fan with. Using a lower guage wire from the power source into a higher gauge wiring from the fan as long as both are rated at same voltage is fine. (in other words a thicket wire from the source of power to a thinner wire of the fan) The fan will only draw as many amps from the source as it is designed to. you get into problems when the use of a smaller wire runs from the power supply a larger wire becuase the smaller wire can't handle the amperage drawn by the bigger wire. hope this helps
bloodbrother Reviewed by bloodbrother on . Cords of Extension... Looking to wire a 6" in-line duct fan to an extension cord. It's just one of those Suncourt 250 CFM inlines. Fan doesn't list the wattage, but my cord is a 14 gauge Medium Duty 15 AMP 125V 1875 max watt. Long story short, I have no problem with @ home wiring due to a history of sound equipment installation... but I want to be sure that my devices are going to shake hands when the juice runs through them. It's just with this project there are less "in-store" professionals to discuss the Rating: 5
