ICC Residential Electrical Inspectors Practice Exam

Receptacles mounted to and supported by a box cover fastened by a single screw shall be listed and ____________ for securing by a single screw.

1. approved

2. identified

3. rated

4. designed

The correct answer is: identified

The correct choice is identified. In the context of electrical installations, certain components must meet specific standards to ensure safety and reliability. When it comes to receptacles mounted to box covers secured by a single screw, they need to be specifically recognized or "identified" for that type of mounting system. This requirement ensures that the receptacles have been tested and are suitable for installation in this manner, minimizing risks associated with loose connections or inadequate support. This identification process ensures that the product's design has been evaluated for its intended application, thus providing confidence in its stability and performance when used in such an installation. This is crucial in preventing issues that can arise from improper mounting, such as overheating or displacement over time. The other choices, although potentially relevant in different contexts, do not specifically address the requirement for receptacles to be recognized for use with a single screw mounting method. "Approved" often pertains to general compliance with safety standards without the specifics related to a mounting configuration. "Rated," typically refers to the electrical ratings associated with the device, and "designed" implies the manufacturing aspect without confirming that the receptacle has been formally validated for that specific use case. Thus, "identified" is the most accurate term to convey the safety and compliance affirmation needed
