WHAT'S A FAN!?

[kngscrpn24]

Hello all,

After four years in FIRST, I still have no idea what a fan is officially classified as. While I must admit I merely scanned the manual every year, this year, as a team leader, I took it upon myself to search out the answer to this question- to no avail (I actually read the manual-!!). Every year we get fans in the KOP, yet only this year have we considered actually using them. SO my questions here are severalfold:

1. What is a fan classified as- "motor" or electronic circuit?
2. What interface is required for a fan? If fans be "motors", then a speed controller is necessary. If not, then I inquire as to what is exactly meant by the power distribution diagram when it has a blank box with terminals marked "fans"- does this warrant me to put in, say, an old breaker-board specifically for fans.
3. Following upon #2, what breaker should be used? The majority of fans in this world only use maybe an amp or two. Somehow, a 20A breaker seams to defeat the purpose of having a breaker.
4. If fans be not a "motor" does that allow the use of non-KOP fans- that is, simply a CPU cooling fan, since it is the ideal size for cooling medium items.
5. If a fan be not a motor, what size wiring should be used to connect to the interface.

I know these questions are a bit extensive, but as far as I can tell, the manual doesn't have a sections devoted to these little creatures OR even the slightest mention (except for the Victor's fans) of them.

HELP!
