Correct setting method for circuit breaker of lighting electrical ready board
The correct setting method of circuit breakers for lighting electrical ready boards is crucial for ensuring the safe and stable operation of the power system. Here are some key steps and precautions:
Choose the appropriate circuit breaker: Based on the rated current and load characteristics of the lighting electrical ready board, select the appropriate circuit breaker model and rated current. Usually, a 1P circuit breaker can be used for lighting circuits, while a 1P or 2P circuit breaker with leakage protection is recommended for socket circuits.
Correct installation of circuit breaker: When installing the circuit breaker, it should be ensured that it is firmly connected to the guide rail or mounting plate inside the electrical ready board, and the wiring terminals are tightly and reliably connected. At the same time, attention should be paid to the direction of the circuit breaker's incoming and outgoing lines to ensure that current flows in from the incoming end and out from the outgoing end.
Set leakage current: For circuit breakers with leakage protection, the appropriate leakage current should be set according to the actual situation. Generally speaking, the leakage current should be greater than twice the normal leakage current to ensure that the power supply can be cut off in a timely manner in case of leakage and prevent safety accidents such as electrical fires.
Indicate circuit name and number: In the lighting electrical ready board, the name and number of each circuit should be indicated so that problems can be quickly identified and located during maintenance or repair.
Regular inspection and maintenance: Regularly inspect and maintain the circuit breakers inside the lighting electrical ready board, including cleaning, tightening the wiring terminals, checking the wear of the contacts, etc., to ensure the normal operation and extend the service life of the circuit breakers.
In summary, the correct setting of circuit breakers for lighting electrical ready boards requires comprehensive consideration of multiple aspects, including selecting appropriate circuit breakers, correct installation, setting leakage current, indicating circuit names and numbers, and regular inspection and maintenance.
