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.n early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses.
Since the shortest swim distance in a triathlon is likely 400â800 meters, and typically more, one needs to consider what training is required to sustain a good pace for the distance to be swum. 800 meters is no sprint.
For short course triathlon, see triathlon. In swimming, the term short course (abbreviated SC) is used to identify a pool that is 25 metres (27.34 yd) in length. The term is also often included in meet names when conducted in a short course pool. Short course is the second type of pool configuration currently recognized by FINA and other swimming bodies for pool competition; the other/primary pool length being long course, where the pool is 50 meters in length.
