Webrelatively small neutral conductors could be used with phase conductors. However, RUS advocates that a neutral conductor have at least 20 percent of the current carrying capacity of the phase conductor with which it is used. Table I shows ACSR neutral and phase conductor combinations based upon this consideration. 6.
