"Smart" Breaker Panel Acceptable for '07?

[whytheheckme]

Can we use 2 maxi blocks?

We have 5 CIM motors total (4 small and 1 large) on our robot, but the MAXI block only has 4 40 amp breakers. The Panel allowed for use of 6; does this mean I need a WHOLE OTHER chunk-o-brass to power just one motor?

You could run the larger CIM off a 30A breaker from the ATC panel .. the stall draw on the large CIM is 40A lower than the smaller CIM, and peak power is 70w less. Not too sure the risk of tripping the breaker, it'll depend on how hard that motor is being ran.

I recall seeing teams from previous years using smaller (1 and 2 port versions) of the MAXI block. The terminal supply co PDF catalog isn't cooperating with me this morning, so I couldn't see if it still existed.

But you are allowed to run another heavy MAXI block if you want.

Cool. 10 minutes ago when I thought that I would need another 4 port MAXI block I could just see my (robot) weight management guy cringe....

I'll look for the 1 or 2 port MAXI... This could be really useful. Our large CIM is driving the whole *elevator* of our robot and needs to be able to lift quite a bit, so I think I'm going to stick with 40 amps.

Thanks for the help,
Jacob

<R45> Items specifically permitted on 2007 FRC ROBOTS include:
One additional 4-slot Maxi-block circuit breaker panel and utilize it on their 2007 ROBOT in addition to, or in replacement of, the circuit breaker panels provided in the Kit Of Parts.

Sorry,
There is no other alternative. Ask this on the Q&A as I suspect they may be lenient in the use of single or dual versions of the Maxi block.
