What should I do first when the hotel room trips, and how can I find out?

The first step is to unplug all the appliances in this room.

Then open it. If it still trips immediately, it means that the lighting circuit is faulty. Visually check the type of lamps in the room. If it is an ordinary incandescent lamp, there may be something wrong with the switch and other circuits. You can check the wiring of bedside table and TV air conditioner. If it is a lamp with electronic components such as energy-saving lamps, turn off the lights or take off the lights and try again.

Next, flip all the switches once, and then turn them off. If they can be turned off, flip the switches one by one. The switch trips when it moves, indicating that there is something wrong with the lights or exhaust fans on this road. If it still trips after or, please continue to the next step.

After pulling all the switches last time, Harbin couldn't close them, indicating that the line was faulty. You can focus on checking the wiring of bedside tables, televisions and air conditioners.

If all the switches have not tripped after recovery, it means that the fault lies in those unplugged power cables. You can plug in the plugs one by one. The problem is which one has tripped.

In short, use the one-by-one exclusion method.
