Edit- Can we connect more than one speed controller fan per breaker?

Edit- Apparently our electronics guy was not clear in his request, and wanted instead to know if we were allowed to connect more than one speed controller fan per breaker. Thanks in advance.

I don't know if you can, but I can't see why not.
However, it is easier to connect the fans directly to the 12V and ground on the speed controller itself since it gives you less wires.

ganging all your fans on one breaker could end up being expensive.

If you wire the fans directly to the 12V input side of each victor, then as long as the victor has power, it has cooling.

If you run the fans off a separate breaker, or put all the fans on the breaker for one victor, then you could end up having all your fans stop when one victor trips its breaker, or if something trips the fan breaker.

then everyone on your team will have to join hands and sing:

"Slow Talking Walter! The Fire Engine Guy!"

(smoke on the water, a fire in the sky :^)

One time, we put all our fans on one breaker. Worked great. The flaw in this idea is if that breaker trips, your screwed. However, if you have good wiring, even 10 stalled fans shouldn't trip a 20 amp breaker. As long as you have no shorts, you should be fine.

Connecting the fan to the power side of the victor is probably a better option but the victor heats up when it is pulling too much current. And when it pulls too much current, it trips the breaker, killing the fan too, and now it has no fan when it needs it most.

Neither setup is ideal. Both work well enough.

thanks a lot guys, ill relay the information to our electronics guy.

One more reason to wire the fan to the input side of the speed controller... When all fans are spinning, you know all controllers are recieving power.

its the unexpected things that will do you in, like a bolt falling off another robot, across your fan circuit breaker, or wires getting pinched in a collision.

We've always hooked the fans up to the victor inputs, I can't imagine the mess of wires you would have connecting them all to the breaker; we have enough of a jungle as it is.
