It sounds like you have your own custom way to distribute the ground. That is OK as long as it isn't electrically connected to your frame, and it is rated for the current that goes through it. For example, if it is on the same circuit as the 120 amp breaker, it must handle at least 120 amps.

The Chippuahaus are the only ones of those that CAN go on the MAXI fuse block. In the rules, it never states (that I can find, perhaps Ken could point me to it) that you CAN'T use anything else. Last year, we got the OK from FIRST ahead of time to use the 30 amp breakers. However, we still had trouble from the inspector as well as the head inspector. We had to talk to the FIRST staff person at Cleveland to confirm.
Ken is right that you CAN get more power out of the motors if you use the 40 amp breakers. However, I was tought to when I designed a system using a DC motor, to always design it so the it uses half the maximum power (1/4 the stall torque). For the Drill motors, this is at barely above 30 amps, and for the CIMs it is barely under 30 amps. Thus, with my designs, I feel somewhat safe using the 30 amps. If we had no weight limit, of course I'd use the higher breaker, but sometimes there are more important things.
