Installation & Wiring Guide
1. Mounting: Securely fix the transformer on a flat, non-combustible surface with adequate ventilation.
2. Grounding: Connect the grounding terminal to a proper earth ground to ensure safety.
3. Wiring: Verify supply voltage matches the transformer’s primary rating (e.g., 480 V for a 480 to 240 transformer single phase).
Use appropriately rated cable and tighten all connections to manufacturer-recommended torque values.
4. Testing: Perform an insulation resistance test (megger) and a no-load voltage test before energizing.

FAQ
What’s the difference between a 480 to 240 transformer single phase and a 480V to 120V transformer single phase?
The main difference lies in the secondary voltage: the former outputs 240 V, while the latter provides 120 V. Both are designed for 480 V primary feeds but serve different end-use applications.
Can I use a single phase transformer for three-phase equipment?
No. Single phase transformers are optimized for single-phase loads. Three-phase systems require three-phase transformers or three single-phase units connected in a specific configuration.
How do I choose the right kVA rating?
Sum the total power requirement of all connected loads (in watts), divide by the secondary voltage, and apply a safety margin (usually 1.25×). For example, a 10 kW load at 240 V needs at least a 52 A transformer → 52 A × 240 V = 12.5 kVA rating.
Are customization services available?
Yes. We offer customized winding ratios, enclosures, mounting styles, and protection features to match your unique requirements.
