PRECAUTIONS AND WARNING
1, Ensure the circuit breaker is properly rated for the current, voltage, and frequency of the circuit it will control to prevent overloading and damage.
2, Always wear appropriate personal protective equipment (PPE) such as insulated gloves, safety glasses, and arc-flash clothing when operating or maintaining the circuit breaker.
3, Verify that the circuit is de-energized using a suitable voltage tester before performing any maintenance or inspection on the circuit breaker.
4, Avoid rapid or frequent switching of the circuit breaker, as this can cause excessive wear on internal components and reduce its lifespan.
5, Follow the manufacturer’s operating instructions and lockout/tagout procedures when isolating the circuit breaker to prevent accidental energization and ensure personal safety.
