What type of plan shows the complete power distribution for an electrical system?

The type of plan that shows the complete power distribution for an electrical system is the one-line diagram. A one-line diagram simplifies the representation of an electrical system by using a single line to depict the interconnected components, such as generators, transformers, circuit breakers, and loads. This diagram efficiently conveys the electrical infrastructure and flow of power, making it easier for engineers and electricians to understand the system layout and operational characteristics without the complexity of a detailed schematic.

In contrast, the other types of plans serve different purposes. RCP, or reflected ceiling plan, focuses on the layout and design of the ceiling and light fixtures in a building. Civil plans pertain to the land, grading, and site layout rather than the electrical distribution. Architectural plans primarily detail the structural and aesthetic features of the building, such as floor layouts and elevations, but do not provide the specific electrical distribution details needed for an understanding of how power is distributed throughout an electrical system.
