When you need to convert 480V of single-phase power supply to 240V, a 480V to 240V Single-Phase Transformer Wiring Diagram is essential. This simple diagram will provide information on how to safely and efficiently wire your transformer. This wiring diagram can be used for both indoor and outdoor applications, to connect the primary transformer.. There will be 240V between X1 and X4 with 120V between X1 and the X2/X3 junction and 120V between X4 and the X2/X3 junction. Again, X2/X3 will be the neutral. Be sure to check with local Electrical Inspectors or Authority Having Jurisdiction (AHJ) for direction about grounding transformers in your local area. Released for: Schneider Electric USA
