Operating Procedures for Pole-Mounted Circuit Breakers

A pole-mounted circuit breaker is a common electrical switching device primarily used to disconnect or connect circuits, providing protection for electrical equipment and ensuring a reliable power supply. Below are the operating procedures for pole-mounted circuit breakers:

1. ​Power Connection: First, ensure the circuit breaker is in the off position. Then, connect the power cable to the input terminal of the circuit breaker. Make sure the insulation sheath of the cable is intact and fully inserted into the terminal.
2. ​Setting the Switch Status: Pole-mounted circuit breakers typically feature a manual operating lever. Move the lever to the desired position (on or off). An indicator on the lever usually displays the current status of the circuit breaker.
3. ​Power Disconnection: To disconnect the power, move the operating lever to the off position. The circuit breaker will then cut off the power supply, creating an open circuit on the line.
4. ​Overload and Short-Circuit Protection: Pole-mounted circuit breakers are generally equipped with overload and short-circuit protection functions. When the current exceeds the set value, the circuit breaker will automatically cut off the power. In such cases, inspect the circuit to identify and resolve the issue before restarting the circuit breaker.
5. ​Resetting the Circuit Breaker: If the pole-mounted circuit breaker trips automatically or needs to be reconnected after manual operation, it can be reset by moving the operating lever to the off position and then back to the on position. Depending on the specific model, a reset button may also need to be pressed.

Please note that operating a pole-mounted circuit breaker may involve high voltage and current, so safety precautions must be taken. If you are unfamiliar with operating pole-mounted circuit breakers, consult a professional electrical technician for assistance.
