When you get into services this big most times theres hardly any Load on the Neutral sometimes the Neutrals installed only because its a WYE system and its required for Grounding Purposes only. The loads are mostly all three phase motors or Transforers 480 to 120/208 volt.When your into smaller services I agree the Neutral ect is of concern.
