Feeder and Service Load Calculations

Design Master Electrical can perform complete feeder and service load calculations based upon NEC 220.40. It can also perform the optional calculations in NEC 220.80.

The following articles in the knowledge base provide more information on the settings needed to perform these calculations:

• Overview of Calculation Methods for Different Types of Buildings: A description of different types of buildings and how to model them.

• Complying with Specific Sections of the NEC: Use this article when you know the NEC reference you are trying to comply with. It tells you how to properly set up your model for that NEC section.

• Correctly Using Load Types: A description of each load type and how it is used in the model.

All of these articles assume a complete understanding of all of the features in Design Master Electrical. We recommend finishing the tutorials first before reading them. They will make more sense after you have learned to use the rest of the software.
