most common US household wires are only two colors, white and black.

i just wired one but would like some more info on your fan before i give you advice that would send 10,000 volts of electricity thru you. :D

pretty simple, some only have two wires, some will have three. one hot wire, one ground wire, and if its use with a 3 prong plug it will have another external ground too.

most cheaper timers dont have the 3 prong plug so it probably wouldnt be used, that was the case with mine.

here is an example.



also how are you trying to wire it, by just adding a cord like the one above so you can just plug it in to the wall or a timer?

the more info you can give about what you are wiring, how you are doing it, and any more info would help me help you ;)

I have a fasco no. 7021-10288, type-u21b, v. 115/230, hz. 60, amp. .90/.45, model no. 4mh41. I'm trying to wire it to a plug just like the one pictured. I've wired lots of things to those plugs but my fan has 5 wires(white, black, blue, red and brown)on one side and two wires(both orange) on th other side. I'm no electrician, i'm kind of at loss!

this is the only thing i could find, and man it wasnt easy either, been searching forever. :)
GO TO PAGE 36, its a pdf file so you will need acdobe reader to open it.

it tells off all the wires but the orange ones.

it looks as though its a 3 speed model.

hope that can help you out cause its all the info i could find for you, that thing didnt come with a instruction book? or maybe you got it used.

good luck man and be careful.

if you look at page 43 also it tells about your style of fan, it mentions a couple things about having a signaling device to let the furnace know its working correctly.

bu looking at page 36 and seeing that they are using the white,blue,black,and brown wires for power, i am "assuming" that maybe the orange ones might be for what ever that signal device is.

i am trying to help ya, i searched for at least an hour and that all i could come up with.

you know you might even shoot the company that makes the like an email and see if they can give you a wire diagram, night save you some headache.

hope you get it all figured out.

in most cases the green wire is just used to ground the caseing , or outer shell of the fan.

hmmmm i am pretty sure its an american style plug, i pulled that pic from a lowes web site, i think it might just look funny cause of the angle its at, but i could be wrong too;)

No, it's a US plug. It has an angled plug on it is why it looks funny.
