What type of covers on wireways are considered unacceptable according to Wendy's specifications?

Hinged covers on wireways are considered unacceptable according to Wendy's specifications because they may not provide the required level of security and protection for the wiring inside. These types of covers can be inadvertently left open or may not close tightly, which could expose the wiring to dust, moisture, and other environmental factors that could lead to safety hazards or equipment malfunctions. Wendy's specifications likely emphasize the need for reliable enclosure that limits access to authorized personnel, ensuring a secure and safe environment for the electrical components. By ruling out hinged covers, the specifications promote the use of more secure and robust cover types that are in alignment with safety standards.
