AC wiring question

[RU482]

I bought an AC blower fan that has 3 wires, Red, Black, and White. Curious how I hook this up to an AC outlet. I plan on taking an AC cable from an old computer and chopping off the end that plugs into the PS.
What I'm not 100% sure on is,
Which color wire plugs into...

The larger vertical slot (1)
The smaller vertical slot (2)
the earth ground pin (3)

Red, Black, and White?

No wonder nobody has touched this. That red ought to be green in my book. Is the damn thing 220V? There ought to be a schematic etched in there somewhere too. Usually, black is common (1), white is hot (2) and green is ground (3). Use an ohmeter to see which wire is attached to the case. That one would be ground and the other two are common and hot.

Hmm, is the fan 220v or 110v? Sounds like 220v.

Diagram of an outlet...

But if it's 220v then this won't work.

If it's 110v, then possible RED is for a switch...

What he said.

Remember, if you have ANY question at all, have someone qualified look at it.

I would like to take this time to say you are on crack. You trying to kill him? black is not gound in 120v systems!! If you don't know dont say.

Black is hot, white is neutral (common) and red is either the second leg for 220v or it is switched/sensing wire. Green is ground. ( which you do not have. The case would be grounded instead, probably through the conduit. )

Outlet: The long slot is neutral, the small is hot, with the little round hole on the bottom being ground.

<edit>
Sorry I am a little pissed. Electricity is nto something you mess with if you do not know what you are talking about. As for why people post guesses without saying they are guesses... Beyond me. about the only black that is ground is in a car. Nothing else. Don't fricking guess, expecialy when your guess can kill someone.

On all the 120V systems I have worked on in the USA BLACK is hot. White is the common with green ground. Could this be variable speed? Red could be for a switch or reostat.

The large blade is for the common. Small blade is hot and round or 'U' shape is ground.

OMG, I can't believe I did that! :Q Listen to Evadman and you won't die. I REALLY don't take electricity seriously enough... obviously!

If it was a mistake, you are forgiven A kid in one of the electricity classes in High School almost killed himself when he was playing with a jacob's ladder. His heart stopped, but the automotice teacher was a part time paramedic, and was able to resistate him. He spent a few days in the hospitcal. That is why I take it so seriusly.

Nope, I need to get shocked good a few more times before I'll start being more careful. I wire outlets hot all the time among other things. Just not enough respect I guess. Always double check my work with a tester and use GFIs all over the house, though. Unfortunately, my carelessness carried over to my instructions to redly, which is just terrible. I ought to put some kind of disclaimer in my sig or something!

Figured it out

white is nuetral
black is hot when you want the blower on high
red is hot when you want the fan on low
