Understanding the THC15A Wiring Diagram

The THC15A wiring diagram is essential for correctly connecting the timer to the electrical circuit. It typically illustrates the following connections:

• Power Supply (L and N): Connect to the live (L) and neutral (N) wires of the power source. Ensure correct voltage (typically 220-240V AC or 110-120V AC depending on the model).
• Load (Output): Connect to the device that needs to be controlled (e.g., a light bulb, pump). This output can be Normally Open (NO) or Normally Closed (NC) depending on the application.
• Common (COM): The common terminal connects to the load and either the Live or Neutral of the power source, depending on the wiring configuration.

Always consult the specific wiring diagram provided with your THC15A timer as variations may exist between models. It is imperative to switch off the power supply before commencing any wiring activities. Double-check all connections before powering on the device.
