you CANNOT just use a 240v circuit breaker from home depot... those are for AC, and unlikely to function if the need arose to open the circuit while under load. DC power is much harder to interrupt, and the circuit breakers are quite different with stronger springs, larger gaps and magnetic blowouts to stop arcing.

consider buying a big fat GE, or using a gang of the AirPax available from one of our dependable EV retailers like kta-ev.com or EVolveElectrics.com
all builds should include a big fat Feraz fuse mid-pack, a circuit breaker with manual pull added, and fuses for everything on the 12v side as well as an inertia switch (mounted vertically) interrupt on your 'key on' 12v power to controller.
