Exhaust fan wiring - safe or sorry?

Hey yall i'm pretty sure this fan is setup right, but just wanted to make sure i'm not gonna light my growbox on fire. Its an AC 120V comp fan- the cords coming out of the fan weren't color coordinated or anything, and I took the cord from a lamp and wired it to the fan. Dont know if this does anything or lights me on fire, but I wired the left wire from the lamp (could tell by the wider prong) to what seemed to be the left from the fan.
when i plug it in it works fine, but i havent tried leaving it in for a long time
thanks:bigjoint:

Yes you should be just fine, if it were a 12 volt dc fan, it would have burnt up instantly when plugging into 120 volt AC. And by burnt up I mean a little puff of smoke would have come out of it, and it would have never worked again. You should always try and keep your splices inside a junction box however, at the very least make sure your wire nut splices are made up tight.

if your using case fans, i would say plug in a comp power supply and then the fans into that. the overhead for running the psu is nominal and you won't have to worry about splices or anything.

If it works - its good. Fans are pretty simple. If you wire them wrong they either vent to the other direction or doesn't function. With PC fans they usually don't function.
Thats about as tough as it gets.

Make sure your wiring is secure and as water resistent as possible - use shrink tubes if available, or electical tape if not. Leaves exposed wires in a humid place is far from smart.
 
those little metal boxes you find inside your walls. they keep all the wireing splices safe from any agitation.
Exactly. They come in metal or plastic and contain and protect the splice. Also if one of your connections did come loose and there was an arc, the junction box would contain it.

If it works your all good...if you wired it wrong it either wouldnt work or would be going in the wrong direction.....if you twisted that nut right and taped it really nice and tight...you need not worry about anything....if the fan is going to "live" wherever you put it then a junction boc would be good...
