What does NEC Article 110.3 require regarding equipment?

NEC Article 110.3 emphasizes that electrical equipment must be installed and used in accordance with the manufacturer's instructions. This requirement is crucial because manufacturers design their products with specific operational parameters and installation procedures to ensure both safety and functionality. Following these instructions helps ensure that the equipment operates as intended, minimizing the risk of failure, hazards, or potential injuries.

Ensuring compliance with the manufacturer's guidelines promotes consistency in installation practices and allows for performance expectations to be met. Additionally, incorrect installation or use that deviates from these instructions could invalidate warranties and reduce the effectiveness of the equipment. Proper adherence to these guidelines also aligns with general safety practices outlined in the NEC, fostering a safer electrical environment.
