What material should be protected from exceeding 90º C (194º F) in lamp holders?

• A. Metal components
• B. Insulation material
• C. Combustible material
• D. Electrical connections

Answer: (C)

The correct answer pertains to the need to ensure that any combustible material in or around lamp holders does not exceed 90º C (194º F). Combustible materials can ignite and pose a fire hazard when exposed to high temperatures. In the context of lamp holders, various components may include materials such as plastics, wood, or other substances that could burn if they reach a high enough temperature. The National Electrical Code mandates that certain safety precautions be taken with regards to lamp holders and their components. Limiting the temperature is a critical aspect of preventing fire hazards, especially in residential or commercial settings where improper installation or malfunction could lead to dangerous conditions. Understanding the importance of protecting combustible materials helps clarify the significance of temperature ratings and safe installation practices surrounding light fixtures. This knowledge is essential for ensuring compliance with electrical safety standards and reducing risks associated with lighting installations.
