Property leakage insurance

If there is leakage or residual current in your home, the 63A open circuit under the property meter box will trip the superior leakage protection switch. If the attribute leakage open circuit is not properly selected, 30mA delay type should be selected (the action time is more than 0.2 seconds later than that at home). There are many reasons for leakage. In addition, the frequency conversion air conditioner at home and the up-converter of inferior fluorescent lamp will cause the leakage circuit breaker to malfunction.
