Arc flash circuit breaker definition.

When a severe enough arc flash occurs the overcurrent protective device fuse or circuit breaker upstream of the fault interrupts the current. But beware the combination function that is identified on recently. Precautions must usually be used when switching circuit breakers such as standing off to the side while switching to keep the body out of the way wearing protective clothing or turning off equipment circuits and panels downline prior. Avoid working on energized electrical equipment and take extra care while testing to ensure it has been de energized or while re energizing it use remote racking technology to operate circuit breakers from outside the arc flash boundary instead of allowing personnel to be put at risk of injury or death.

An arc fault circuit interrupter afci also known as an arc fault detection device afdd is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires. A combination arc fault circuit breaker is not equivalent to a dual function circuit breaker. The amount of incident energy a worker may be exposed to during an arc flash is directly proportional to the total clearing ampere squared seconds i 2 t of the overcurrent protective device during the fault.
