What would be a characteristic of enclosures designed for outdoor use?

Enclosures designed for outdoor use need to be watertight to protect electrical equipment from moisture, rain, and other environmental factors that could lead to short circuits or equipment failure. The watertight feature is essential because outdoor environments often expose enclosures to various weather conditions, and moisture ingress can pose serious safety hazards, including electrical shorts and corrosion.

While lightweight, ease of installation, and color-coding could be beneficial in certain contexts, they do not specifically address the critical need for protection against environmental elements that enclosures face outdoors. Therefore, ensuring that outdoor enclosures are watertight is paramount to their effectiveness and safety.
