What type of voltage does irrigation wiring usually operate on?

• A. 220 Volt for controllers
• B. 110 Volt for irrigation controllers and 24 Volt for valves
• C. 48 Volt for mainline connections
• D. 12 Volt for all functions

Answer: (B)

Irrigation wiring typically operates on low voltage to ensure safety and efficiency in managing water resources. The standard for irrigation systems involves using 110 Volts in controllers, which are responsible for regulating the operation of the entire irrigation setup. This voltage allows for adequate power to operate various components such as timers and remote control systems.

In addition, a common practice is to use 24 Volts for the solenoid valves within the system. This lower voltage is preferred because it reduces the risk of electric shock and is more efficient for the activation of valves that control water flow.

Using 110 Volts for controllers and 24 Volts for valves creates a safer and more manageable operating environment, allowing for effective landscape irrigation while minimizing potential hazards associated with higher voltages.
