This section details the key components and their importance, along with examples of materials used in various applications and recommended choices for different climates.
Materials for Box Construction
The durability of an outdoor electrical box hinges on the material used for its construction. Common choices include steel, aluminum, and fiberglass-reinforced polymers (FRPs). Steel, a traditional material, offers excellent strength and corrosion resistance when properly coated. Aluminum, while lighter, provides good corrosion resistance, but its strength might be a concern in some applications. FRPs, a composite material, provide high strength-to-weight ratios, excellent corrosion resistance, and are often preferred in demanding environments.
Covers and Gaskets
Protecting the internal components from the elements is critical. Covers, typically made of the same material as the box or a compatible material like coated steel or FRP, ensure the enclosure remains watertight and protects the electrical connections. Gaskets, often made of EPDM rubber or silicone, create a tight seal between the cover and the box body, preventing moisture ingress and maintaining the integrity of the enclosure.
Mounting Hardware
The mounting hardware secures the box to its location. Corrosion-resistant stainless steel or galvanized steel are typical choices for screws, bolts, and brackets. The appropriate size and type of mounting hardware must be chosen to ensure the box is firmly attached and resistant to vibration or impact.
Examples of Material Usage
Different types of outdoor electrical boxes are designed for specific applications and environments. For instance, steel boxes with powder-coated finishes are common in residential settings, offering a balance between cost-effectiveness and durability.
