Why did the hotel trip with a low-power boiler?

In every hotel room, the air switch is small. Using a small rice cooker will cause the air switch to trip.

The hotel is not allowed to cook in the room, so as not to damage the interior decoration by oil smoke, because there is no kitchen in the general hotel room. Unless the hotel has an executive apartment type room. Because this room has a kitchen, it can burn cold fire. There is no room for high-power appliances in ordinary rooms. This is done for security reasons.
