Where is an acceptable location for a screw or nail fastening a device box to a framing member?

An acceptable location for a screw or nail fastening a device box to a framing member is permitted up to 1/4 inch from the back or end of the box. This specification is important for ensuring that the fastening does not interfere with the box's functionality or structural integrity. Fastening too closely to the back or end can risk damaging the box or the electrical components that may be housed within it.

By allowing a margin of up to 1/4 inch, it provides a balance that prevents potential risks while ensuring secure attachment to the framing. This practice adheres to safety standards and building codes, which emphasize proper installation techniques to minimize hazards associated with electrical installations.
