WEBA 480V 3 Phase System consists of three conductors, each carrying an alternating current with a voltage of 480V. These conductors are typically labeled A, B, and C, and they are 120 degrees out-of-phase with each other. This phase offset allows for a more balanced distribution of electrical load and improves efficiency.
