Even with layout and location drawings, what essential information might be missing between components?

Wiring is essential for establishing connections between components in an electrical system. While layout and location drawings provide a visual representation of how components are arranged within a space, they might not show the specific wiring details needed for installation or connection. This information includes wire types, sizes, and the pathway of how power flows from one component to another.

In particular, layout drawings typically focus on the physical positioning of electrical components rather than the intricate details of the wiring connections between them. Understanding wiring is crucial for ensuring that all components operate correctly and safely. Without clear instructions or diagrams showing how components are interconnected through wiring, installers may face challenges in understanding how to complete the circuit properly.

The other aspects, such as terminal strips or relative locations, while important, do not fundamentally address the need for understanding how the components communicate electrically through wiring.
