What is the minimum requirement for each zone in terms of Load Centers?

The minimum requirement for each zone concerning Load Centers is that there must be at least one port and one starboard Load Center. This requirement ensures redundancy and balance in electrical distribution across the zones. By having both port and starboard Load Centers, it provides a backup in case one side encounters issues, such as overloads or failures. This setup enhances the safety and reliability of the electrical system, as it prevents total loss of power to one side of the vessel or facility, which is crucial in maintaining operational capabilities.

Having only one port or one starboard Load Center would not meet the redundancy needed for a robust electrical management system. The provision for at least two Load Centers, while beneficial for additional capacity or distribution efficiency, does not satisfy the specific requirement of having both port and starboard centers as outlined in the question. Therefore, the requirement is focused on ensuring that both sides of the distribution system are equipped to handle electrical loads effectively and safely.
