NEC Article 300.28 outlines what about installation techniques?

NEC Article 300.28 specifically addresses the proper installation techniques that help reduce electromagnetic interference (EMI) in electrical systems. This is significant because EMI can adversely affect the performance of electrical equipment and communication systems. The code emphasizes that installations should be performed in a way that minimizes the potential for interference, ensuring that the electrical systems operate effectively without disrupting sensitive electronic devices.

While aesthetics, emergency situations, and energy efficiency are relevant topics in electrical installations, they do not fall under the specific focus of Article 300.28. The emphasis on reducing interference is crucial for maintaining the integrity and reliability of electrical systems in various environments. This is why the correct answer highlights the importance of proper installation techniques aimed at minimizing EMI.
