Circuit Manager To search for a panel, enter the panel name above the list. You can view the properties of each circuit in the Circuit Manager. ■ Expand a specific panel to list all circuits by system type assigned to that panel. ■ Expand a circuit type under a panel (for example, Power and Lighting) to list all circuits of that type assigned to the panel. The right pane of the Circuit Manager lists information about the circuits in your drawing (or in all drawings, if you are using the electrical project database). The information is based on what you selected in the left pane-a panel, circuit type, or circuit. Overloaded circuits display in red. While you can modify some circuit properties using the Circuit Manager, other properties are displayed for reference and are read-only. For example, you can modify the name and description of a circuit, but the number of poles and phases (for ANSI) are read-only. For circuits whose system type is specified as Power and Lighting, you can use the Circuit Manager to calculate wire sizes based on the circuit rating. When checking wire sizes, you have the option of automatically resizing them if they are undersized or oversized when compared to the calculated sizes. The header section of the Circuit Manager contains information from the panel object properties and circuit settings for the selected panel, including voltage, phases/wires, panel rating and type, main rating size, design capacity, AIC rating, mounting, and enclosure. The footer section contains calculations for connected loads and demand factor, including a summary and totals for connected loads for each load category, totals for each load category multiplied by the demand factor, demand load total and available spare capacity, and load distribution among the phases. Electrical Objects Electrical objects are the components you use to design electrical systems. Devices, panels, and wires are referred to as electrical objects. Most objects, such as receptacles, switches, and telecommunications outlets, are typically displayed symbolically, and are not drawn to scale in plan view. Objects such as lights also display symbolically, yet they are scaled to their actual envelope dimensions in plan view. This enables you to easily place the lights to achieve your desired lighting density, and it also enables you to check for interferences among larger electrical components and surrounding systems. Devices Typically, the first step in drafting an electrical plan, such as a power or lighting plan, is to place the devices and panels in the appropriate locations on the floor plan. AutoCAD MEP provides a library of electrical devices that includes most of the elements that you need to complete your plans: ■ Power receptacles Electrical Objects | 357
