33.1    Neutral Conductors

Neutral conductors of supply circuits, other than in distribution systems of 5000 volts or less with common primary and secondary grounded neutrals, shall be considered as carrying the same voltage as the other conductors of the circuits.  Insulators used to support neutral conductors shall meet the requirements of Rule 55, based on the nominal voltage of the circuit, but are not required to have the same insulating value as insulators actually used on the phase conductors.  Where a common neutral system is installed, the neutral conductor may be considered as carrying the same voltage as any of its related systems conductors, compliance with special practices and construction requirements being necessary (see Rule 59).
