2. In the case of high power consumption in summer, or when the home line fails, the home leakage protector may trip. If there is a sudden power outage and there is electricity in the neighbor's house, you can check whether the leakage protector trips. If it trips, push it up. Generally, the leakage protector will be in the distribution box at home, and the old community may be exposed.
3. If the leakage protector has not tripped and there is a fuse, you can also check whether the fuse is blown. Generally, old communities will have fuses. In case of power failure, pull out the buckle of the fuse, and then check whether it is blown. If so, go to the hardware store to buy some fuses and connect them.
If you don't pay the electricity bill for a long time, there will be power failure. At this time, you can check whether the electric meter display in your corridor is normal. If it is displayed in other homes, it is not displayed in your own home, which may be due to arrears. Or check whether there is any arrears through the electric number. Pay the arrears and call later.
5. If the electricity meter shows normal, it means that there is power failure at home. Leakage protector will trip if it can't be pushed. There are two reasons: First, the leakage protector is damaged. Second, the home line is short-circuited.
6. You can turn off all the electrical appliances in your house and step on the brake again to see if it will trip. To rule out whether there is an electrical short circuit.
7. You can also turn off the main switch under the main meter, and then remove all the wiring under the leakage protector. Turn on the main switch under the blood glucose meter again. Try to push on the leakage protector. If it still trips, it means that the leakage protector is damaged and can be replaced with a new one.
