What does a dark or brown color change in high temp wire insulation indicate?

A dark or brown color change in high temperature wire insulation typically indicates that the insulation has undergone thermal degradation. This can happen when wires are subject to excessive heat, leading to a breakdown of the insulation material.

The correct interpretation of this condition is that the insulation has likely become brittle and can crack, which means it may not provide adequate protection against electrical faults, posing safety risks such as shorts or fires. The change in color suggests that the insulation is compromised and the wire may need to be replaced to ensure safe operation.

In summary, the condition of the insulation directly impacts the wire's functionality and safety. Recognizing such signs is critical for maintaining electrical equipment properly and preventing hazards in commercial food service environments.
