If you want to... assign the devices to a circuit then... for Show circuits from panel, select the panel that contains the circuit. You can select from the panels in the current drawing, or in the electrical project database. Then, for Circuit, select the circuit. IMPORTANT To use the instant sizing tool to calculate the wire sizes, you must select a circuit whose system type is Power and Lighting. You cannot select Unassigned or a circuit of different system type. NOTE As you connect the devices with wires, the software assigns the devices to the specified circuit unless they are already assigned to one. In this case, the Circuit property cannot be changed. You can manually create a multiple-branch circuit by changing the specified circuit as you add wires, or by drawing a wire between 2 devices that are already assigned to different circuits. Specify wire sizes 8 Expand Dimensions, and specify the wire sizes by doing one of the following: ■ On the Dimensions bar, click to have the instant sizing tool calculate the sizes. The tool calculates the sizes based on ■ The material and temperature rating of the wire, which are specified in the wire style ■ The rating of the specified Power and Lighting circuit ■ The ambient temperature specified in the drawing. For information about specifying the ambient temperature, see Configuring Circuiting Options on page 366. ■ Select or enter wire sizes for the hot, neutral, ground, and isolated ground wires. The wires for which you need to calculate or specify sizes depend on the design specifications of the selected wire style. Insert the wires 9 Connect the devices with wires: If you want to... then... insert the wires manually in the drawing, use electrical snaps to manually specify the devices to connect with wires. For an example, see Example: Drawing Wires on page 417. NOTE As you connect the devices with wires, on the Properties palette you can view the assigned circuit (Connected circuits) and its total load (Connected load). In the case of multiple-branch circuits, all circuits and their total loads are shown. generate the wires enter g (generate) on the command line to generate wires between all the devices assigned to the specified circuit. 416 | Chapter 9 Drawing Electrical Systems
