Which statement is true regarding mounting electrical equipment to certain wall types?

The statement that wooden plugs are not permitted for mounting is correct because wooden plugs can deteriorate over time, especially in environments with significant moisture or temperature variations. They may not provide a reliable or secure method of anchoring electrical equipment to walls made from more rigid materials. In contrast, anchoring methods that use metallic or composite materials, such as metal brackets or proper anchoring systems for each specific wall type, are designed to ensure a longer-lasting and more robust attachment of electrical equipment.

Various wall types, like cinder blocks or bricks, have specific requirements for mounting. For instance, cinder block typically requires metal brackets or concrete screws for secure mounting, while brick may need specific anchors designed for its density and material properties. Each wall type demands careful consideration of materials used for mounting to guarantee safety, structural integrity, and code compliance. This understanding of mounting practices reflects best industry practices for ensuring equipment is securely attached and operational over time.
