Maybe someone here can give a complete electrician noob some advice. I'm trying to wire a In-line duct fan up in my buddies closet. The fan is a small 4" 120 vac, 60hz, 0.25amps. It has a wire rated 600v 18awg. Can I use a wire thats 300v 16awg that plugs diretly into the wall? I've hooked it up to test it, and it seems to work fine, but if im gonna run it for 12 hrs at a time i want to be sure this little thing doesn't mess up our whole run.
