Anyway, as long as we're using 40A snap action breakers on each circuit, the capability of the 885 won't be exploited. We'd get a small benefit in reduced voltage drop. For FRC use that doesn't seem worth the difference in price.

885s seem to be intended for big bots. 24V x 120A is 2880 Watts; at about 75% efficiency that would be about 3 HP at the motor shaft. Way too much power for a FIRST robot, even if we were to get motors that could handle it.

Yep. Your absolutely correct. There is no way that we need that much power on the field unless FIRST was taking a turn for the worst turing it into BattleBots.. (Thank god its not)
