What defines "accessible" wiring methods?

"Accessible" wiring methods are defined as those that can be reached and removed without causing damage to the building structure or the wiring itself. This means that if there is a need for maintenance, repairs, or modifications, the wiring can be accessed efficiently and safely. The ability to remove the wiring without causing damage is crucial in ensuring the longevity of the installation and the safety of the electrical system.

The other choices describe situations that restrict access rather than promote it. For instance, wiring that is closed in by walls or secured in place permanently would not be classified as accessible since it would require significant effort or damage to reach. Similarly, wiring that is buried underground presents challenges when it comes to access, as it would likely require digging or other invasive measures to reach it. Thus, the concept of being able to remove wiring easily and without damage is essential to defining accessible wiring methods.
