Transcript
The ampacity of the neutral conductor is generally permitted to be equal to or greater than the calculated maximum single-phase unbalance of the load. Where a significant portion of the load is non-linear, the neutral should be full size. The generator neutral supplied by GeneratorJoe is equal in ampacity to the phase conductors. Flexible metal conduit and stranded conductors must be used for connections to the generator set to take up generator set movement and vibration. The flexible conduit should be at least 18 inches (460 mm) long. Medium voltage cable must be installed and terminated exactly as recommended by the cable manufacturer, by persons who have learned the procedures through training and practice under close supervision.
