When defining loads, you can define area-based loads and equipment loads.
Define Area Based Electrical Loads
Create area-based loads to define a closed region and indicate power requirements based on power/area density. For example, lighting in 2nd floor office spaces is 2w/ft2, while lighting in conference rooms is 3w/ft2, and general power across the entire floor is 3.5 w/ft 2.
Assign equipment loads to define load requirements associated with major equipment components, such as elevators, chillers, or any other component beyond the general power density-based loads.
When you define the conceptual distribution system, you can create power sources, busses (panelboards and switchboards), transformers, and transfer switches. Like electrical equipment families, you can interconnect these components to sum loads in the distribution system. Loads can be defined as three phase or single phase. Additionally, you can then associate area and equipment loads with the busses to tabulate load on each equipment component in the system concept.
