third harmonics, the cross-section of neutral conductors should be at least 1,73 times the cross-section of the phase conductor. Generally, ... In a circuit, the conductors with load current are taken into account. If the load in a polyphase circuit is presumed to be symmetrical, it is not necessary to take the neutral ...
