Three-phase high-leg delta installation measuring power coming from a power utility (grid).

Example Wiring Diagram

Example Configuration

Notes

• Wiring and configuration is identical to a standard three-phase site. The only difference is in the voltages measured on L1, L2, and L3: – L1 and L3 are 120Vac to neutral. – L2 is 208Vac to neutral.
• It does not matter whether the high-leg is wired to L1, L2, or L3, as long as all three phases are measured.
