What is a drawing that shows the connection between point A and point B called?

A wiring diagram is a comprehensive representation that illustrates the physical connections and layout of an electrical system. It details how various electrical components are interconnected, enabling electricians to understand the specific pathways for current flow between different points, such as point A and point B.

Wiring diagrams are particularly useful because they provide a clear and detailed orientation that includes the positions of components, their terminals, and the overall arrangement of the wiring. This clarity is essential for troubleshooting, installation, and ensuring that the system operates safely and efficiently.

While the other options have their specific uses, they do not convey the same level of detail regarding the connections involved. A wiring schematic usually emphasizes the electrical functions rather than the physical connections, an electrical blueprint refers to engineering layouts that may include other aspects of construction beyond wiring, and a connection illustration might be a more general term without the precise electrical context found in wiring diagrams. Each serves a purpose, but for the clear relationship between specific points in a wiring context, a wiring diagram is the most appropriate choice.
