A computer-based method and apparatus are provided for designing a building's electrical power distribution system. An eNode module accepts user input and collects global project information for an entire electrical power distribution system project. The eNode module extracts and imports the electrical power distribution system project data from separate building equipment and panel board modules and calculates various total electrical loads for the overall system. The eNode module automatically determines the need for accommodating transformers between electrical nodes and flags errors in the specification of panel boards and electrical equipment based on the calculated total loads. The eNode module specifies transformer requirements and determines these errors with the aid of electrical standards data, such as the National Electrical Code. Finally, the computer-based invention automatically generates an electrical parts inventory for constructing the electrical circuits in the building, including transformers, which may be electronically transmitted to a parts supplier for fulfillment. |
