Is the property responsible for the burning of the computer caused by the connection of electricity to the property power supply station?

It should not be the responsibility of the property. Property management is based on the property service contract. If you don't charge your property fee, you won't be responsible. The main electrical box belongs to the owner's property, and the property is only managed by the owner. If it is maintained on time, you will not take any responsibility. You should be talking about the zero line, not necessarily the main electrical box.
