Unlike devices, panels, and wires, electrical equipment does not work with circuits. You can only connect equipment to physical wireways such as conduit and cable tray. In some cases, such as a junction box, there are both devices and MvParts available in the electrical catalogs. The junction box device works with circuits and connects to wires. The junction box MvPart connects with conduit based on the conduit’s nominal size. Nominal size (also called trade size) is a diameter dimension provided in addition to actual outside diameter values, in compliance with industry standards.
Electrical drawings are usually shown in 2D, where devices and panels are represented with symbols, and wiring is represented with single lines. In plan view, electrical MvParts display the actual part geometry to scale. You can display equipment in 3D. For example, you might want to show a 3D model that includes the electrical equipment, conduits, and cable trays for the building. In this case, you can display the real-world geometry of the objects in a 3D view.
