The dormitory tour will not resume automatically. Need to check the wiring and electrical appliances first, and found a small blue button on the panel that is not guaranteed. When it trips, this little button will pop up automatically, so you need to press it back and then push the switch up.

Because the overload exceeds the rated load, the dormitory will trip due to overload protection. Schools often set certain load limits. If students use high-power appliances such as rice cookers, hair dryers and heaters in the dormitory, the load will increase and the current will also increase. If the load exceeds the preset limit, it will trip. If there is electrical leakage, it will lead to leakage protection tripping, line aging, incomplete insulation, flooding, etc., which can lead to short circuit of the line. If the instantaneous current is too large, the protection device will automatically trip, thus protecting the circuit system.
