Standard Requirements For Overload Protection And Leakage Protection Of Lighting Electrical Ready Boards
The standard requirements for overload protection and leakage protection of lighting electrical ready boards are crucial to ensure the safe operation of electrical systems. The following is a detailed explanation of the standard requirements for the protection of these two aspects:
Overload protection standard requirements
Functional requirements: The electrical components inside the lighting electrical ready board must have overload protection function, which can automatically cut off the power in case of overload, preventing electrical components from overheating or damage.
Device standard: Overload protection devices must comply with the provisions of GB 14048.2 standard. The overload protection action switch should adopt a protection action switch with inverse time limit characteristics, and its breaking capacity should meet relevant requirements.
Installation position: The overload protection action switch should be installed at the beginning of the circuit or at the point where the current carrying capacity of the conductive metal body decreases, to ensure that the power can be quickly cut off in case of overload.
Requirements for leakage protection standards
Action current and action time: The leakage action current of the leakage protector should be less than 30mA, and the action time should be less than 0.1s to ensure that the power can be quickly cut off in case of leakage and prevent electric shock accidents.
Installation requirements: Leakage protectors should be installed inside the lighting electrical ready board and installed and wired according to relevant standards to ensure the normal operation of the leakage protectors.
Testing and maintenance: Regularly test and maintain the leakage protector to ensure its good performance and ability to function in critical moments.
In summary, the lighting electrical ready board has strict and comprehensive standards for overload protection and leakage protection, aiming to ensure the safe operation of the electrical system and the safety of personnel's lives and property.
