In case of 3Phase Supply,
Voltage R-Earth/Neutral - 220
Y-Earth/Neutral - 220
Z-Earth/Neutral - 220
Total is -> 660Volts

Then Why it is said that 3Phase supply is 440

Answer Posted / n

220 Multiply by root three is equal to 281.4 volts. for 440
volts single phase voltage up to 254 volts.

Is This Answer Correct ?    3 Yes 8 No
