What are the maximum dimensions of a lighting fixture that may be supported only by the screw shell of the lamp holder?

• A. 12"
• B. 14"

• D. 18"

Answer: (C)

The maximum dimensions of a lighting fixture that may be supported solely by the screw shell of the lamp holder is 16 inches. This is regulated to ensure safety and prevent potential hazards caused by excessive weight or dimensions of the fixture that could lead to instability or failure. When a fixture exceeds this limit, the risk of it falling or becoming loose increases, which can pose a danger to individuals nearby as well as damage the electrical components involved. It is essential for electricians and installers to adhere to these guidelines when planning installations to ensure compliance with safety standards and proper functionality of the lighting system. Understanding this limitation is crucial for maintaining safe electrical installations, protecting both the integrity of the installation and the safety of occupants within the space.
