Maintenance of electric meter line attributes

The power supply department is responsible for the external wiring of the electric energy meter; The wire between the home watt-hour meter and the distribution box is the responsibility of the property; After the distribution box, I'm in charge of the wires. In any case, the house has nothing to do with the property management company. There is a simple reason. The property management company is just a service enterprise. In principle, it has nothing to do with developers and builders. He has no obligation to deal with these problems for developers; Many times, owners like to blame this problem on the responsibility of the property management company. The property management company can't repair it, but it has to pay for it, including the cost of materials and labor. When did you say there was no electricity at home? Did you get the key at first, or did you live for a while? If there is no electricity at first, it is the responsibility of the developer. If you get the key for more than two years, the owner is responsible. Because what you said is not very clear, I can't judge the specific situation, but I can tell you responsibly, generally speaking, unless it is an old house line, the problem is not big, especially after 90 years, the entrance line of the building is protected to a certain extent, and it is rarely thought of or destroyed by rats. You can check whether the interface is oxidized or loose.
