# How do you step down 460 3 phase to 240 3 phase?

You step down 460 3 phase to 240 3 phase using a three phase 460 volt to 240 volt step down transformer.

### Is 277 volt and 277 volt equals 460 volt?

No, voltages in a wye configuration are not additive. Calculations for wye connection used the nominal voltage of 480 volts. The voltage of 277 volts is derived from the the phase voltage of 480 divided by the square root of 3 (for three phase) . 480 / 1.73 = 277 volts. For phase voltage of 460 the coil voltage to ground will be 460/1.73 = 266 volts.
