*1. The frame size and model of MCCB, RCD or ELCB (with overcurrent protection function) change according to the ca-
pacity of the power transformer. For details on selection method, refer to related technical data.
*2.
The recommended size of wire to the main circuit terminal is the size when PVC wire having an allowable temperature
of 70°C and a rated voltage of 600 V is used, and the ambient temperature is 40°C.
*3. Only one wire of recommended size can be connected to the ground terminal.
