Which of the following is NOT an acceptable option for attaching receptacles or covers according to manufacturer’s instructions?

The selection of screws for attaching receptacles or covers is crucial for ensuring safety and compliance with both code standards and manufacturer's specifications. Screws are typically designed to secure components without damaging the structural integrity of the box.

Using screws that are larger than the box's gauge is problematic because such screws can compromise the box's integrity, leading to physical damage or deformation. This can interfere with the safe installation of electrical components, potentially creating a hazard. The gauge of the box is intended to dictate the appropriate size and type of fasteners to use, ensuring a secure fit that doesn't over-extend or puncture through the material.

In contrast, machine screws, drywall screws, and wood screws can all be acceptable provided they match the requirements set by the manufacturer. Each of these types of screws has specific applications and strengths suited to different materials, and they can be used effectively to secure receptacles and covers when chosen appropriately. Thus, it’s imperative to adhere to the manufacturer's instructions regarding the proper screw type to ensure safety and efficiency in electrical installations.
