Group Motor Protection
... Typically, group motor installations protected by one branch circuit OCPD and group switching are considered for cost savings. However, caution should be taken where a conductor is expected to be protected by an overcurrent protective device significantly greater than the conductor ampacity. The NEC ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
