Typical “General Lighting Circuit” Settings

Posted on June 20th, 2016. Last updated on June 14th, 2023.

This article describes the most common General Lighting Circuit settings used in Design Master Electrical.

At the Project Level

  1. Run the Options command.
  2. In the Distribution Equipment section, set Default general lighting circuit value to No.
  3. Press the OK button to save your changes.

At the Distribution Equipment Level

  1. Run the Panels command (or the command appropriate for the distribution equipment types that exist in your project).
  2. Press the Feeder and Service Calculation Settings button. Make sure the Default General Lighting Circuit Value is set to Default (No).
  3. If you are calculating lighting based upon the area of the building, go to the Occupancy Areas section. Configure the area based upon the power density.
  4. Press the OK button to save your changes.

At the Circuit Level

  1. Run the Circuiting command.
  2. On the right, find the General Lighting Circuit setting. It should initially be set to Default (No) for all circuits in the project.
  3. Set it to Yes for circuits that have loads that are considered “General Lighting” by the NEC. See NEC 220.45.

Any load on a circuit that is set to Yes will be ignored in the panel load total calculation. It is assumed to be included in the load calculated based upon the area of the building.
