What requirement does Article 110.43 make concerning electrical layout plans?

Article 110.43 of the National Electrical Code emphasizes the need for layout plans to accurately reflect the actual installation. This requirement is crucial as it ensures that all aspects of the electrical system are clearly documented, allowing for better understanding, inspection, and maintenance of the installation. Accurate layout plans help minimize errors during installation and ensure compliance with safety regulations and standards.

When plans are detailed and true to the actual installation, they serve as a reliable reference for electricians and inspectors, facilitating safe practices and adherence to the code. This approach aids in troubleshooting and future modifications, as it provides a clear view of how the system is laid out, including the placement of circuits and equipment.

The other options do not align with the NEC's intent of ensuring safety and clarity through precise documentation. Generic plans or those based on previous installations without updates can lead to confusion or misinterpretation, compromising safety. Similarly, following a common template may not account for the specific details required by individual installations, which is why a tailored approach is necessary.
