Can a box serve as a support for other equipment?

A box can indeed serve as a support for other equipment, provided it is specifically listed for that use and meets the necessary load requirements. This is vital in ensuring that the box and the equipment it supports remain safe and functional under operational conditions.

When a box is listed for supporting equipment, it means that it has been tested and certified to handle the stress and load imposed by the devices attached to it. This certification helps in ensuring that the box will not fail under weight, thus preventing potential hazards such as electrical fires or equipment damage.

The load requirements refer to specific engineering standards that dictate how much weight the box can safely handle. Compliance with these standards ensures that the installation will be reliable and secure.

Other options present inaccuracies regarding the potential for boxes to support equipment. Some suggest limitations that do not align with the NEC's guidelines about support and safety, making them less applicable in a real-world context. Therefore, understanding that a box can support equipment when appropriate conditions are met is crucial for adhering to safe electrical practices.
