How many seconds does the leakage protection last in the primary distribution box
For the action time (maximum interruption time), it is set to not exceed 0. For lighting electrical ready boards, which are usually terminal distribution lines, the rated residual operating current of their leakage protectors should be set to 30 mA. This is a standard value that balances the safety of preventing electric shock and avoiding misoperation. Splash-proof protector should be used in wet and corrosive media sites, and its rated leakage current should not be more than 15mA. Rated electric. Earth leakage devices detect current imbalances within 30 milliseconds and cut power before you receive a dangerous dose of electricity.
