Hey guys im in need of some assistance. I just got my booster fan and i have no idea how to wire it. I'm hoping someone here has already had to do something similar to this. I assume its like wiring anything else, ive just never wired anything. All i know it you ground one of the wires to a screw.

I can't tell...is there any indication on the black rubber coated wires as to positive or negative?

OK guys i found something form a previous thread!

"99% of the time brown is hot,blue is neutral, and green/yellow is chassis ground

connect one black wire to the brown, connect the othe black fan wire to the blue wire, and connect the green/yellow wire to any metal part of the fan housing with a screw. use a short screw and don't put it in near the motor.... stay on the ends"


Can someone now please just explain to me how you connect wires? just twist the ends together?

the green is earth ground - after that it doesn't really matter for that particular item

twist together and wrap in electric tape or screw a cap on - if you use tape, cover ALL EXPOSED AREAS

Green wire gets attached to the fan housing for a ground. Black wire on fan with the white stripe to the brown. Solid black wire from fan to the blue wire. Even if you get the brown and blue backwards it will still work. Just be sure they green wire has good contact with the fan housing.

STOP!!
motors run on a DC (battery) power supply!! those wires are from an AC (household) power supply
and i doubt its 600v a fan that size is usually 12-24v and does not need a groundwire
is there a spec anywhere on the unit? if you want to plug it into the wall you will need a transformer to convert the power down from 240v AC (or whatever it is there) to 12v DC
when you have that the 2 wires can be wired either way depending on what way you need the fan to turn

prefrebly soilder them together but if it needs to be removable from the power supply you should use crocodile clips

WTF dude. Thats a 120v AC duct booster from Home Depot or the like. And the 600v is just the max rating for the wire.

theres no detalis on that
but it must, i use an air-hockey table fan that runs on AC , only because it has a built in transformer
motors cannot run on AC without them.....if it has one then it was my mistake....and i hereby withdraw my comment.....

The best thing would be to use wire nuts. Those are the cap like things that you screw onto two or more wires to connect them. Color typically defines capacity. If you don't have wire nuts, not big deal though. Just strip about a half inch from each wire. Put the bare ends of both wires parallel to each other and twist them together into a pigtail. then bend the braid back parallel to the wire (doesn't matter which way). Then wrap with a couple inches of vinyl electrical tape. If you use wire nuts, use some tape on that too, to make sure it never vibrates off or something.

Home depot is a 20 mile trip, I hope electrical tape will suffice, thanks for the reassurance.

You absolutely do not have a clue what you are talking about.

ever notice the larger plug on a phone charger compared to the plug on your TV??? yano the one that gets hot....thats a transformer its basically a electrical converter that allows a battery opperated device run on a household power supply....thats it in a nutshell, motors need a direct current (DC) to spin
