What is the minimum clearance required between luminaires and the lowest surface of metal-corrugated sheet roofing decking?

1 inch
1 1/4 inches
1 1/2 inches
2 inches

The correct answer is: 1 1/2 inches

The minimum clearance required between luminaires and the lowest surface of metal-corrugated sheet roofing decking is 1 1/2 inches. This requirement is crucial for ensuring safety and proper heat dissipation. Luminaries generate heat during operation, and maintaining the specified clearance helps prevent overheating, which could lead to potential fire hazards or damage to both the lighting fixtures and the roofing materials. The clearance requirement is established to ensure that there is enough space for air circulation around the luminaire, minimizing the risk of heat buildup. It's essential for electricians and installers to adhere to these guidelines to comply with safety codes and to promote the longevity of the lighting fixture in various environmental conditions.
