because if we change the sequence of ryb the resultent vector of suppy gets reversed .

Answer / rajeshkumar k

suppose RYB phase sequence is correct,we start a motor it will rotate in correct direction,and motor is safe...if phase sequence is not correct voltage and current will flow and direction will be reverse and it will affect the motor and motor will get damaged.so we should check the phase sequence when we will start a motor
