Series wiring is commonly used in applications where multiple lights are controlled by a single photocell. 2. Parallel Wiring Configuration. Parallel wiring involves connecting the photocell in parallel with the lighting load. In this configuration, the photocell and the lighting load are connected to the same power source separately.
The photocell acts as a sensor, detecting the level of light and signaling the lighting fixture to turn on or off based on the pre-set threshold. When wiring the system, the power source is typically connected to the photocell through a dedicated circuit. The photocell is then wired to the lighting fixture, completing the circuit.
A typical photocell requires circuit wiring connection which would include the green ground wire, white neutral wire and the black circuit power wire. The Load Wiring Connection The Load wiring of the photocell is typically where the black wire that leads to the light fixture is connected to the Red wire of the photocell.
