Why is the Size of the Neutral Conductor Smaller than the Line Conductor in a Polyphase System? In a three-phase (poly-phase) system, the Neutral wire may sometimes be smaller than the Line wire under specific conditions. However, the Neutral wire and cable size must match the Hot (Live, Line, or. In general, it is not recommended to distribute the neutral conductor, i. When a 3-phase 4-wire installation is necessary, however, the conditions described above for TT and TN-S schemes are applicable. This ensures balanced current distribution and safe operation. However, in situations where the system has unbalanced loads, such as in single-phase applications or systems with varying phase loads, the neutral wire may need. and in case where all load in three phase is single phase is larger neutral wire than phase wire is required ?, and how to calculate neutral wire capacity (amp) for case where transformer is three phase but all loads is single phase ? Because the phase currents cancel out.
