In Delta connection, phase sides are connected in a cyclical arrangement in order to make a closed loop as shown in figure 1. Line and Phase currents are related to each other as: I_line=square_root(3)*I_phase Which means that whatever supply current we have, we need a wire cross-section for 1/ square_root(3) times line current only. Whereas, in Delta connection, Line and Phase voltage are same such as: V_line=V_phase
