One reason a low voltage transformer might overheat is due to exceeding the load rating with simultaneous operation. When a transformer is subjected to a load that is greater than its designed capacity, it generates excess heat as it struggles to supply the required power. This heat buildup can lead to overheating, which may eventually damage the transformer or affect its performance.

In the context of transformers, maintaining a proper load is crucial because each transformer has a specific power rating it can handle safely. Operating at or below this rating ensures that the transformer functions efficiently without overheating. If multiple devices connected to the transformer draw current simultaneously, the cumulative load might surpass the transformer's capacity, leading to overheating issues.

The other factors mentioned do not contribute to overheating in the same manner. A cold environment would not cause overheating; it might actually help with cooling. Matching voltage ratings is critical for functionality, but it does not directly cause overheating. Lastly, while wire thickness can affect resistance and heat transfer, being too thick typically does not cause overheating; rather, it is often the insufficient or incorrect gauge that can lead to issues.
