Power losses must be roughly evenly distributed within the enclosure. No Interference: not applicable

Internal air temperature ≈ 40°C (ambient) + 27 K = 67°C → acceptable for most devices. iec tr 60890 pdf

The is a technical report titled "A method of temperature-rise verification of low-voltage switchgear and controlgear assemblies by calculation." It provides a standardized procedure for assessing the air temperature rise inside enclosures without the need for physical testing, which is particularly useful for verifying designs in a cost-effective manner.
