  1. to bring the imbalance current back to the source. No system is truly balanced in practice. There will always be some unbalances between loads. Another advantage for having a neutral is protection for the loads. If one load for some reason stops working, not having a neutral will cause a voltage spike in the other 2 loads potentially destroying the loads.
