MM ALS Notes

The wye is symmetrical; each phase (A, B, C) to the neutral is the same & equal to voltage from line-to-line divided by √3 (or 1.73) typical system voltages 120/208 & 277/480, where lesser voltage is line-to-neutral voltage, the greater is line-to-line. Where a neutral to a delta voltage from B & C it neutral = ½ the phase-to-phase voltage. ................
