What distinguishes rainproof construction?

Rainproof construction is distinguished by its ability to prevent water interference under specified conditions. This characteristic is essential because it ensures that electrical devices and systems can operate safely and effectively even in wet environments. Rainproofing typically involves design elements that direct water away from critical components, ensuring that moisture does not enter enclosures or contact live electrical parts.

This prevention is key to the reliability and safety of electrical equipment when exposed to rain or moisture. It allows devices to maintain performance and reduces the risk of short circuits, corrosion, or other water-related failures. While resistance to mechanical impact and the use of waterproof materials may contribute to a device's overall durability and protection against environmental factors, it is the specific capability of preventing water intrusion that directly defines rainproof construction.
