Because of the installation problem in security window, the property cuts off the owner's power supply privately. What should the owner do?

It may be illegal for the property to cut off the electricity consumption of the owner privately because of the installation problem in security window, because the property company has no right to take such measures against the owner. Here are some steps you can take:

1. First of all, you should keep calm and don't try to repair the power yourself to avoid danger.

You can protest to the property management company, clearly point out that their actions are illegal and ask them to restore power supply. At the same time, you can also ask the property management company to rectify the security window issue to comply with relevant regulations.

3. If the property management company refuses to restore power supply or solve the problem, you can reflect this matter to the Electric Power Bureau and other relevant departments and ask them to intervene and solve the problem.

If the above steps still can't solve the problem, you can consider hiring a lawyer or legal adviser to file a lawsuit with the relevant departments to safeguard your legitimate rights and interests.

In short, as the owner, you have the right to ask the property management company to abide by relevant laws and regulations and take legal measures to solve the problem. If the measures taken by the property management company are unreasonable or illegal, you can take corresponding legal measures to safeguard your rights and interests.
