    The aim of connecting two transformers on parallel is to divide loads equally between each them, provided that the specifications of both two transformers must be identical. Any difference will lead to an unequal distribution of the loads between them, and as a result, one of the transformers will bear the largest load and consequently damage and collapse in the near future as a result of high heat due to overload.
