The neutral should be equal to or less than the phase currents. If all loads are line to neutral then the maximum neutral would be equal to the phase, however when using split phase 120v to ground or 240 leg to leg any devices that do not use a neutral would have no neutral currents.
Line voltage = Phase voltage. The measure of current in one phase before the star or delta arrangement of the component is called line current (typically input current in motor or output current in the alternator). In three phase balanced system, it may be R phase current or Y phase current or B phase current. It is denoted by I L ampere.
For a Y-connected three-phase generator, the phase voltage and phase current are the output voltage and current from each coil. The line voltage is the voltage measured between any two output lines (conductors). The line current is the current flowing in a line. Image used courtesy of Amna Ahmad
If all loads are line to neutral then the maximum neutral would be equal to the phase, however when using split phase 120v to ground or 240 leg to leg any devices that do not use a neutral would have no neutral currents. So your maximum neutral current will always be equal or less than the addition of the legs.
In delta connection: Line voltage = Phase voltage. The measure of current in one phase before the star or delta arrangement of the component is called line current (typically input current in motor or output current in the alternator). In three phase balanced system, it may be R phase current or Y phase current or B phase current.
In three phase balanced system, it may be R phase current or Y phase current or B phase current. It is denoted by I L ampere. In star connection: Line current= phase current. (we get it from applying Kirchhoff’s current rule.) In delta connection: Line current= phase current. (we get it from applying Kirchhoff’s voltage rule.)
