It is quite possible to operate two transformer in parallel, but condition is both must have same voltage. Here at one side of transformer there is voltage difference with the factor of (3)^1/3 and circulating current will flow at one side of the transformer leading to the increased ohmic losses and thereby efficiency decreases.

What is the difference between ELCB and RCCB. Please define the working of both.
