What does an electrical wiring schematic show?

An electrical wiring schematic provides a simplified representation of a circuit, illustrating the path of electricity through various components. This means it focuses on how power flows from the source, through switches, resistors, and other devices, indicating the connections and interactions between them.

This schematic does not show the physical layout or exact location of each component; instead, it emphasizes the relationships and pathways of the electrical flow. Additionally, while knowing the load capacity and potential voltage drop in a circuit is important for design and safety, these factors are not represented in a wiring schematic, which is primarily a tool for understanding and troubleshooting the circuit's functionality and electrical pathways.
