Showing 0:34–0:49 of the source video.
What happens in this clip
The wiring process begins by connecting the incoming main power supply to the first motion sensor switch, which is positioned at the bottom of the staircase. The Line (Live) wire, typically red, is connected to the 'L' terminal of the motion sensor. The Neutral wire, typically black, is connected to the 'N' terminal of the motion sensor. This provides power to the motion sensor itself.
Goal: Supply power to the initial motion sensor switch.
What's used
Tools
- Line (Live) Wire
- Brown electrical wire (IEC)
- Motion Sensor Switch (Bottom)
- Neutral Wire
- Blue electrical wire (IEC)
About the full video
This project visually demonstrates the initial steps of wiring a motion-activated stair lighting system. It shows how to connect the main power supply to a motion sensor switch and then extend the live and neutral connections to multiple recessed LED stair wall lights. Due to video segment limitations, the complete circuit including a second motion sensor and final connections is not fully depicted within the provided timestamps.
Step 5 of 7: Wire Motion Sensors and Power Supply
Wire the motion sensors according to their manufacturer's instructions. Typically, the sensor will be connected between the power supply and the LED strips. Ensure correct polarity. The power supply will then be connected to a mains power source.
