The present invention relates to a distribution board having an embedded panel transformer. The distribution board includes a panel transformation unit (B), a terminal box ( 200 ), a converter ( 210 ), and a control unit ( 300 ). The panel transformation unit includes a plurality of panel transformers (A). Each of the panel transformers includes a transformer ( 130 ) having the same capacity and the same load characteristics, and an automatic circuit breaker ( 140 ) for connecting or disconnecting the transformer to or from a load. In the terminal box, low voltage power is connected to a low voltage cable. The converter is installed in the terminal box, and detects the amount of load current flowing through the low voltage cable. The control unit compares the amount of load current with a preset reference data value, operates automatic circuit breakers, and connects or disconnects corresponding panel transformers to or from the load.
