What is the difference between phase switching and phase rotation?

Key differences between phase rotation vs phase switching

  • Phase Rotation: Involves how you connect the wires to the terminals, determining the sequence in which the phases are arranged.
  • Phase Switching: Focuses on distributing power evenly across different phases to optimise power usage, particularly beneficial for EV charging.

Implementing phase switching during EV charger installation is advisable for more efficient and smarter use of available power.

 

Understanding phase rotation

Phase rotation refers to how you connect the phases to the terminal. In other words, it involves connecting the wires to the hardware to make it function correctly. When setting up, you can connect the three different phases (L1, L2, and L3) in various ways to the terminal.

The terminal will always have the same order for connections, labeled as L1, L2, and L3. However, the actual phases connected to these terminals can vary. For example, you might connect your L2 phase to the L1 terminal. If this is the case, the phase rotation will be L2 connected to the L1 terminal, with the remaining connections potentially looking like L3, L1. 

 

Understanding phase switching

Phase switching is the process of distributing power between different phases to optimise the use of available power, especially in the context of EV charging. This helps ensure electricity flows evenly across all phases.

In summary, phase switching is about balancing power distribution for a better charging experience by efficiently utilizing the available power. This makes phase switching a recommended setting when installing an EV charger, as it ensures you use the available power more effectively and intelligently.
