Wiring behind heating panels in interior walls is considered to operate at an ambient temperature of how many degrees Celsius?

Wiring behind heating panels in interior walls is generally considered to operate at an ambient temperature of 40 degrees Celsius. This temperature is applied because heating panels can contribute to elevated temperatures in surrounding areas, which affects the conductors installed in those locations. The National Electrical Code (NEC) provides guidelines for the installation and rating of electrical components based on the expected ambient temperatures they may encounter, especially in environments influenced by heat-generating devices. Therefore, assuming a 40 degrees Celsius rating helps ensure the safety and reliability of electrical systems in such settings. Understanding these guidelines is essential for maintaining the integrity of electrical systems and preventing overheating or electrical failure.
