Dwelling Unit Load Calculations

How to calculate feeder and service loads for dwelling units in Design Master Electrical.

We look at the following topics for configuring dwelling unit loads:

  • Configuring loads on the panel with the Feeder and Service Calculation Settings dialog box
  • Configuring fixed loads on the circuit with the Set Circuit Information dialog box
    • The General Lighting Circuit ▾ option
  • Configuring panels for multifamily dwelling units

We also answer the following questions:

  • "Which load calculation method should be used for an apartment building?"
  • "How is the Future Demand field used?"
  • "Can you configure a receptacle to be recognized as a fixed load rather than as a receptacle?"
  • "How should receptacles in the living space be configured?"
  • "Are exhaust fans entered as an Appliance Motor?"
