Demand factors are assigned to load categories and load categories are assigned to device connectors. The estimated load for a device is calculated by using the load and the value for the demand factor. The estimated demand load is displayed in the Circuit Manager and in the Panel Schedule. The Panel Schedule also shows the load for each load category style. TIP The default templates contain several load category styles that you can copy and modify. To create a load category definition 1 Click Manage tab ➤ Style & Display panel ➤ Style Manager drop-down ➤ Load Category Definitions . 2 Click Load Category Definitions. Right-click, and click New. 3 Enter a name, and press Enter. 4 Select the new load category style. 5 On the General tab, enter a description for the load category. 6 On the Demand Factor tab, select the demand factor type. 7 Specify the value(s) for demand factor as necessary. Configuring Electrical Preferences Before you begin creating circuits, you can specify electrical preferences for the following features: ■ Voltages that will be available for the project ■ Circuiting features, such as naming conventions, overload checks, and wire sizing factors ■ An electrical project database file that contains panels and circuits for the project NOTE For information about the electrical project database file, see Using an Electrical Project Database on page 381. Specifying Voltage Definitions Use the Voltage Definitions tab of the Electrical Preferences dialog to enter valid voltages for different numbers of poles. The voltage values are the default values available when you are working with devices and circuits. Each voltage definition has a minimum value and maximum value that define the valid range when a device is to be connected to a circuit. NOTE Voltage settings for 2-pole and 3-pole should be the same, otherwise some values may not be available in the Circuit Settings worksheet. To define voltage definitions 1 From the Electrical workspace, click Manage tab ➤ Preferences panel ➤ Electrical . 2 In the Electrical Preferences dialog, click the Voltage Definitions tab. 3 Select a pole type, click (Add Voltage Definition), and then specify the voltage amount, the minimum value, and the maximum value. NOTE To delete a voltage, expand a pole, select a voltage, and click (Remove Voltage Definition). Configuring Electrical Preferences | 365
