Limiting the discussion just to Victor fans for the moment, the way I read the rules you don't have to have these fans attached to a speed controller at all, they just have to have been attached to speed controller that was in a FRC KOP in some year (i.e. they have to be Victor Fans).

The really attractive thing about this rule (IF I AM CORRECT about not having to use them for their original purpose) is that they can be used in unlimited numbers and they can be powered directly via a 20A breaker per Table 4-2 in R48. That is, you don't have to be able to turn them off when you are disabled. Turn on the main breaker and your fans go on.

The way I read this, you could make a hovercraft with hundreds of these guys if you wanted to as long as you powered them all via the 20A breaker.

Am I wrong?
