Article 110.20 states that equipment must be installed in a manner that avoids what?

Article 110.20 of the National Electrical Code emphasizes the importance of installing electrical equipment in a way that minimizes potential physical hazards and prevents damage to the equipment itself. This provision is critical because improperly installed or maintained equipment can lead to safety risks, such as electrical shock or fire hazards. Furthermore, protecting equipment from damage ensures its longevity and effectiveness, ultimately contributing to a safer electrical system overall.

Physical hazards may include situations where equipment could be subjected to mechanical impacts, moisture, or excessive heat, all of which can impair functionality or create unsafe conditions. Thus, the correct answer highlights an essential aspect of safe electrical installation practices that align with the broader goals of the NEC in promoting safety and reliability in electrical systems.

The other options, while important considerations in various contexts of electrical installation and system design, do not directly address the core intent of Article 110.20, which is centered on avoiding physical hazards and protecting equipment integrity.
