Photocell Wiring Diagram Uk

By | July 9, 2022



Picture this - you're trying to install a photocell switch in your home, and you've come across the dreaded Photocell Wiring Diagram UK. It looks like an alien language; how are you ever going to understand it?

Never fear; wiring diagrams don't have to be confusing. Understanding the basics of a photocell wiring diagram can help make sure your installation goes smoothly.

To understand how a photocell works, think about how a normal switch controls a light. You flip the switch, and the contacts close, allowing electricity to flow through the circuit. With a photocell, you also flip the switch - but instead of closing the contacts, the switch triggers the photocell to turn the light on or off depending on the amount of light present.

In a photocell wiring diagram, symbols represent the various components involved in creating the circuit. In the UK, this typically includes a live (L) feed, a neutral (N) feed, a switched line (S) feed, and an output (O) line. The photocell is connected between the live and switched lines, with the output line connecting the photocell to the lamp. Underscoring all these symbols is the 'supply' line, which provides the electrical current to power the circuit.

Once you've found your diagram, understanding it is the easiest part of the process. All you need to do is follow the symbols to make the correct connections. Connect the supply line to the live and neutral lines, then connect the photocell between the switched line and the live line. Finally, connect the output line to the lamp's load and voila! – you’ve made your photocell circuit. With the circuit complete, all that's left to do is flip the switch and turn the lights on.

Whether you’re a first-time installer or a seasoned electrician, understanding a photocell wiring diagram is essential for a successful DIY project. Knowing what the symbols mean will make the task of wiring a photocell much easier and quicker, so next time you come across one, don't be intimidated - use it to your advantage!
