Power Distribution Block Grounding

Actually, you are connecting the fuse panel to the block, not the victors or the motors...

I hope that you are not going to use six of the same motor, because

<R45> Items specifically permitted on 2007 FRC ROBOTS include:
<snip> One or two additional 2-1/2” CIM motors (part #FR801-001) in addition to those provided in the Kit Of Parts. This means that up to four, and no more, 2-1/2” CIM motors can be used on the ROBOT.

One additional 3” CIM “Minibike” motor (part #FR801-005). This means that up to two, and no more, 3” CIM “Minibike” motors can be used on the ROBOT.

Now, four of one kind and two of the other would be just fine.

You would need two of the golden "Maxi" fuse panels in the case of 2 + 4 big motors.


There should be no concerns with using the SEVEN total available connection points on each part (red/black) of the power distribution block. Although one often sees installations where the inputs are on one side and the outputs on the other, that all changes when you install and use the yellow bus bar jumpers - that is exactly what they are made for!

Also, remember that in this case the term "grounding" is incorrect - when your motors are running in reverse, the black wire has a positive polarity. Victors reverse!
