When selecting cable size, the ambient environment design temperature is a crucial factor to consider. This temperature represents the maximum expected temperature the cable will be exposed to during operation. Cables can carry different amounts of current based on temperature; as temperature increases, the resistance of the cable can rise, leading to potential overheating and performance issues.

The ambient environment design temperature helps determine the heat dissipation capability of the cable and ensures that the selected size will adequately handle the current load without exceeding temperature ratings. Adequately accounting for this temperature ensures reliability and safety in electrical systems, minimizing the risk of insulation breakdown or fire hazards.

Other factors, such as ambient humidity and conductivity limits, play roles in overall cable performance but do not specifically address the direct impact of temperature on current-carrying capacity the way the ambient environment design temperature does. Machinery durability, while important for overall system design, is less relevant in determining cable size specifics related to temperature.
