Types of 2-Gang Outdoor Electrical Boxes

Standard Weatherproof Box

The standard weatherproof electrical box is designed to protect electrical connections from moisture and debris. Typically made from durable materials such as plastic or metal, these boxes are ideal for outdoor outlets and switches. Their weather-tight seals ensure that electrical components remain safe from the elements, making them a popular choice for home improvement projects.

Recessed While-in-Use Box

Recessed while-in-use boxes provide a sleek, low-profile solution for outdoor electrical installations. These boxes are designed to hold outlets or switches while remaining flush with the wall surface. This design not only enhances aesthetics but also provides protection against the weather. Ideal for patios and decks, these boxes can accommodate various electrical configurations.

Ground Box

Ground boxes are specialized electrical boxes used for underground installations, such as landscape lighting or irrigation systems. Made from robust materials, ground boxes are designed to withstand soil pressure and moisture. Their weatherproof features ensure that electrical connections remain safe and functional even when buried.

In-Use Recessed Box

Similar to the recessed while-in-use box, the in-use recessed box is designed to protect electrical components while maintaining a clean appearance. These boxes are often used in residential and commercial applications, providing convenience for outdoor receptacles that require protection from the elements. Their design allows for easy access to electrical connections without compromising safety.

Surface-Mount Box

Surface-mount boxes are used for applications where traditional recessed installation is not feasible. These boxes can be mounted directly onto walls or other surfaces, making them ideal for retrofitting existing structures. Made from weather-resistant materials, surface-mount boxes provide robust protection for electrical components exposed to outdoor conditions.

Key Features to Consider

When selecting a 2-gang outdoor electrical box, it is essential to consider various features that will affect performance and longevity.

Weather Resistance

All outdoor electrical boxes should be rated for weather resistance. Look for products labeled as “weatherproof” to ensure they can withstand rain, snow, and humidity. Materials like PVC, fiberglass, and metal with protective coatings are often used for enhanced durability.

Load Capacity

Ensure the electrical box can handle the electrical load you intend to place on it. The load capacity varies by design, and it’s crucial to adhere to local electrical codes to avoid overloading.

Ease of Installation

Installation complexity can vary between different models. Some boxes come with additional features like mounting brackets or easy-to-access knockouts, which simplify the installation process.

Aesthetic Design

For outdoor spaces, aesthetics can be just as important as functionality. Consider recessed options that blend seamlessly with walls, or decorative covers that enhance your outdoor environment.
