What common elements are found in the construction of an industrial wiring device?

The construction of an industrial wiring device typically includes assembly screws, back body, cord grip, and terminals as fundamental components.

Assembly screws are essential for securing various parts of the device together, ensuring mechanical stability and proper alignment during operation. The back body serves as the main structural component that houses internal parts and connects to mounting brackets or bases. Cord grips are crucial for providing a secure entry point for cables, preventing strain on the connections and enhancing safety by minimizing the risk of accidental disconnection. Terminals facilitate the electrical connections necessary for the device to function, allowing the wires to connect securely without compromising the overall integrity of the device.

Overall, option B encompasses the key components specific to the construction and operation of industrial wiring devices, highlighting their importance in creating reliable and safe electrical connections in industrial environments.
