A paddle fan is proposed on an outlet box that is listed only for luminaire support. What is required?
- AUse longer cover-plate screws
- BReduce the fan speed setting
- CSupport the fan from branch conductors
- Use a box or support system listed for ceiling-suspended fans
Why D is correct
A ceiling-suspended fan imposes dynamic mechanical loads that an ordinary luminaire box may not be evaluated to carry. The outlet box or independent support must be identified for fan support and the fan weight.
