# Can we remove the neutral wire?

If we have the connection shown below (star connection of the secondary part of a TX), the load per each phase is equivalent (balanced load), then the vector sum of I1, I2 and I3 is zero. In this case, I would like to ask if we can remove the neutral wire from the connection since no current will flow in it (theoretically at least)?

And if we can remove it, where is the return path (to form a closed circuit) for each phase current?

• The return path is distributed over the other two phases. If I1 is positive, then at least I2 or I3 has to be negative to make their sum (I1 + I2 + I3) zero. – stevenvh Apr 9 '12 at 15:15
