What is the proper method for mounting receptacles that are set back from the wall surface?

Supported by screws
Rigidly at the surface of the wall
Loosely against the wall
With a flexible mount system

The correct answer is: Rigidly at the surface of the wall

The proper method for mounting receptacles that are set back from the wall surface is to ensure they are rigidly at the surface of the wall. This method is crucial because it guarantees that the receptacle is securely anchored and fully accessible for plugging in devices. Proper alignment with the wall surface helps prevent any potential hazards, such as stress on the wiring and connections, which could occur if the receptacle is not mounted flush. It also simplifies the installation of covers and ensures that they fit properly, providing both safety and a neat appearance. In situations where receptacles are set back, ensuring they are brought to the surface guarantees that all electrical components remain safely housed and that users can easily interact with the receptacle without obstruction or risk of accidental disconnection.
