What is the maximum weight for a luminaire that can be supported by an outlet box specifically listed for its weight?

The maximum weight for a luminaire that can be supported by an outlet box specifically listed for its weight is 50 lb. This standard is set to ensure safety and structural integrity when luminaires are installed. Outlet boxes that are rated for specific weights have undergone testing to confirm that they can handle loads up to this limit without risking failure or creating hazards such as electrical shorts or physical collapse.

When considering the load-bearing capability of outlet boxes, it's paramount to adhere to these ratings to ensure that installations meet NEC requirements and that they promote safety in residential and commercial settings. Supporting a luminaire that exceeds this weight could result in dangerous consequences, such as the outlet box breaking or becoming dislodged from the structure, potentially leading to damage or injury.

Understanding these weight limits is crucial for anyone involved in electrical installations or modifications, as compliance with these standards is key to maintaining a safe environment and preventing violations of the NEC.
