How high must a permanently mounted lighting fixture be located above the floor in a commercial garage?

8 feet
10 feet
12 feet
14 feet

The correct answer is: 12 feet

A permanently mounted lighting fixture in a commercial garage must be located above the floor at a height of 12 feet to ensure safety and efficiency. This height is established in electrical codes to minimize the risk of damage caused by vehicles and equipment commonly found in commercial garages. Mounting the fixtures at this height helps prevent accidental contact and ensures that the light is effective in illuminating the workspace, which is crucial in environments where visibility is essential for safety and operational effectiveness. Additionally, fixtures positioned higher can reduce the accumulation of dust and debris, contributing to better maintenance and longer lifespan of the lighting equipment.
