Concepts and Procedures

This section describes concepts and procedures you will use with Design Master Electrical. It describes how to apply the commands in the Command Reference section to create your electrical project.

📄️ Definitions: Distribution Equipment and Branch Circuit Device

We have two definitions that are unique to our software: distribution equipment and branch circuit device. The electrical industry as a whole does not have words that match these terms. We use these terms in our software because they help organize how we create the model of your electrical system.

📄️ Project Drawing and Database Management

When you create a new project, a database file will be created in the same folder as the current drawing. The file name will be dm_elec<Name>.dm, where <Name> is the name of the project. This is the database file where all of the information about your project is stored. Your project drawings are now connected to this database file, and the information contained in the drawings and the database must match.

📄️ Master and Standards Databases

The master and standards databases are used to store default settings for new projects. You can make changes to the customization settings, store them in these files, and reuse them.

📄️ Overloaded Distribution Equipment

When running the Update Distribution Equipment Schedule or Update All Schedules and One-Line Diagram command, if any of the affected schedules show an overloaded distribution equipment, the Overloaded Distribution Equipment dialog box will appear.
