Select the NEMA or industry standard symbol associated with a specific component shown in a wiring diagram.

In the context of wiring diagrams, the NEMA or industry standard symbols are crucial for identifying electrical components accurately. Choosing the correct symbol helps in understanding the function and specifications of the component represented. Each symbol correlates directly with a specific type of electrical equipment or device, such as motors, switches, transformers, or receptacles.

The choice is justified if it correctly matches the specified component's function in electrical installations. For example, if the symbol in choice A represents a standard motor symbol, and the wiring diagram indicates that a motor is present, then marking A is accurate as it directly aligns with industry-standard practices. Proper identification using these symbols ensures compliance with electrical codes and enhances safety during installations and troubleshooting.

Understanding these symbols is essential for any electrical contractor, as using the correct representation not only aids in documentation but also facilitates clear communication among electricians and service personnel regarding the components involved in a project. Being familiar with NEMA standards contributes significantly to preventing errors and ensuring the effectiveness of electrical systems.
