If bare or covered conductors are installed with insulated conductors, how should their temperature ratings compare?

When bare or covered conductors are installed alongside insulated conductors, it's essential that they have the same temperature rating. This requirement ensures safety and compliance with electrical standards. The reason behind this is that all conductors in a given installation need to operate effectively under the same thermal conditions to prevent overheating and ensure reliable performance.

If conductors have differing temperature ratings, the insulated conductors might not handle the heat generated by the bare conductors adequately, leading to potential insulation degradation or failure. By requiring that all conductors have the same temperature rating, the installation promotes uniform thermal management and reduces the risk of electrical faults or hazards.

In summary, uniform temperature ratings among conductors help maintain safety and performance standards in electrical installations.
