Solution:

The advantage of implementing a three-phase circuit is cost-savings. Three-phase circuits are more efficient with their transferal of electrical power; therefore, they are capable of powering much more at a lower cost. Office buildings and manufacturing plants can still operate with single-phase circuits although they would be more efficient with their power supply if they made the switch to three-phase circuits. The real difference between single-phase and three-phase circuits can be seen in large data centers and manufacturing buildings. These large facilities require more power to run their operations and will therefore witness greater efficiency and savings by making the switch.
