What must documentation include alongside ventilation requirements in electrical installations?

In electrical installations, particularly in marine environments, ensuring adequate ventilation is essential to prevent overheating and to facilitate safe operation. Temperature requirements are critical in documentation as they dictate the ambient conditions under which electrical systems must operate effectively and safely. Including temperature requirements ensures that the installations are designed with considerations for the thermal limits of electrical components, thereby preventing potential hazards such as overheating, which can lead to failure, fire, or damage to equipment.

The other options do not directly align with the core focus on ventilation. While generator specifications might be relevant in some contexts, they do not specifically address the ventilation aspects of the electrical installation. Current ratings are important for understanding the load capabilities of the system but do not inherently relate to how well the installation is ventilated or how it manages temperatures. Warranty details concern the coverage and guarantees for the equipment but do not directly impact the operational safety relating to ventilation. Thus, temperature requirements stand out as the essential element to include in documentation regarding ventilation in electrical installations.
