Final answer:
The temperature limitation of ENT is 90 degrees Celsius, which ensures the safety and integrity of the wiring contained within ENT in a high temperature environment.
Step-by-step explanation:
The temperature limitation of ENT (presumably Electrical Nonmetallic Tubing) is 90 degrees Celsius. This is often the case for certain types of electrical conduit materials which must be able to maintain their integrity and insulating properties at high temperatures. It's important to adhere to these temperature ratings for safety and to prevent damage to the wiring contained within the tubing. Remember, the thermoneutral external temperature for the human body may be around 84 °F, which is far below the maximum operating temperature of ENT. Also, understanding the temperature limitation helps you appreciate the material's energy conservation capacities and its role in maintaining a safe environment for electrical systems.
