What does Article 410 say about non-socketed lamps in luminaires?

Article 410 of the National Electrical Code (NEC) addresses various requirements related to luminaires, including the use of non-socketed lamps. The correct answer highlights the necessity to follow the manufacturer's instructions and relevant safety standards when utilizing non-socketed lamps in luminaires. This is crucial because these lamps often have specific installation and operational requirements to ensure safety and reliability.

The manufacturer’s instructions typically include guidance on how the lamps should be installed, connected, and maintained. Adhering to these instructions can help prevent hazards such as electrical shock or fire that may arise from improper usage. Additionally, following safety standards ensures compliance with broader regulations designed to protect public safety.

In contrast to this, the other options incorrectly suggest that these lamps can be used in a more casual manner, neglecting the importance of safety guidelines and proper installation practices. This understanding is pivotal for anyone working with electrical fixtures to ensure both functionality and safety in installations involving non-socketed lamps.
