Because the integrated ceiling is made of aluminum-magnesium alloy, and aluminum can conduct electricity, it is a good conductor, which is also a leakage phenomenon, so it will trip under the effect of safety protection, so repair it in time as soon as possible.
Here's a diagram to show you: read it and you'll understand. >>>More
After the air switch is divided into 3 floors, two wires are led to the room, and the live wire and the zero line are measured with an electric pen, if the live line electric pen is on, if the zero line electric pen light is not on, the switch should be connected to the live line, do not connect to the zero line, so it is safer. If you haven't connected the line before, you still have to be careful, I hope it can help you.
It's best to thread the wire through a metal hose before sealing it! If the line is sealed alone, leave a certain distance between the zero line and the live line!

The zero line is connected to the earth, because the ceiling keel is grounded, for example, when playing the suspension bar, the expansion screw of the suspension bar touches the steel bar. >>>More
