What is a common feature required for installation of outdoor electrical devices?

Weatherproof housing is a common requirement for the installation of outdoor electrical devices. This feature is crucial because outdoor environments expose electrical devices to various elements, including rain, snow, and humidity. Weatherproof housing typically includes enclosures that are designed to prevent moisture and dust ingress, thereby ensuring the safety and functionality of the devices installed outdoors.

These housings are usually rated according to specific standards such as the Ingress Protection (IP) rating, which indicates their effectiveness against environmental conditions. Using weatherproof housing not only protects the internal electrical components from damage but also helps prevent safety hazards such as short circuits or electric shocks caused by water intrusion.

While features like temperature regulation, enhanced voltage, and insulation resistance are important in specific contexts, they do not universally apply to the basic requirement for outdoor installations in the same way that weatherproof housing does.
