Wiring a Photocell

Wiring a photocell is relatively simple, but you should take care to ensure that the wiring is done correctly. The first step is to locate the positive and negative wires for the photocell. The positive wire is usually red, and the negative wire is usually black. Once you have located the wires, connect the positive wire to the power supply, and the negative wire to the load. If the photocell is rated for a certain voltage, then make sure the power supply matches that voltage.

Using a Diagram

There are a few different types of diagrams, but the most common is the wiring diagram for a 120-volt photocell. This diagram will show the two wires that need to be connected, and how to do so. It will also indicate which wire is the positive and which is the negative.

If you are unsure of how to wire the photocell, you should seek the help of a professional electrician. They will be able to guide you through the process and make sure everything is done properly and safely.
