Photocells, also known as photoelectric cells, are sensors that detect light. They are commonly used in outdoor lighting fixtures to automatically turn the lights on at dusk and off at dawn. Wiring a photocell is a simple process that can be done by following a few steps.
When installing a photocell, it is important to first shut off the power to the circuit you will be working on. This will ensure your safety while working with electrical components. Once the power is off, you can begin the wiring process.
Photocell Wiring Diagram
Start by identifying the black and white wires coming from the photocell. The black wire is the hot wire, while the white wire is the neutral wire. Connect the black wire from the photocell to the black wire from the light fixture, and connect the white wire from the photocell to the white wire from the light fixture. Use wire nuts to secure the connections.
Next, locate the red wire coming from the photocell. This wire is typically used for switching the light fixture on and off. Connect the red wire from the photocell to the black wire from the light fixture. Again, use a wire nut to secure the connection.
Finally, connect the green or bare copper wire from the photocell to the ground wire in the light fixture. This wire is used for grounding and provides an additional level of safety. Once all the connections are secure, you can turn the power back on and test the photocell to ensure it is functioning properly.
In conclusion, wiring a photocell is a straightforward process that can be completed with basic electrical knowledge. By following the steps outlined above, you can easily install a photocell in your outdoor lighting fixtures to automate the on and off function based on light levels. Remember to always prioritize safety when working with electricity and consult a professional if you are unsure about any aspect of the wiring process.
