Waterproof electrical boxes are available in polycarbonate plastic, aluminum, and steel varieties and are common in industries such as alternative energy, agriculture, oil and gas, food and beverage, marine, and more.
We offer a variety of waterproof NEMA accessories to ensure final products maintain NEMA and IP ratings. Read more below for key information that will help you choose the best weatherproof box for your needs.
Applications of Waterproof Enclosures
Waterproof enclosures fulfill a wide range of purposes. They can guard sensitive electronic equipment, or they might serve as electrical outlet boxes or electrical junction boxes in harsh environments. Many are designed to work as either indoor or outdoor electrical boxes, with features that allow them to excel in either role. Anywhere that water hazards such as wet weather or hose spray threaten electrical and electronic equipment, waterproof enclosures are must-haves.
Whether you’re using them to house receptacles, control panels, circuit breakers, or another type of equipment, it’s critical to select waterproof enclosures that meet your needs. First, determine the protective requirements of your specific outdoor application. Outdoor outlets have different needs from electronics on a factory floor, which have different needs from high voltage switchgear. Some might be in a sheltered area and only need protection from light precipitation, while others might require full NEMA 6P submersion resistance.
Get familiar with the NEMA and IP rating scales, to understand the level of protection your enclosure needs. It’s also important to learn about the differences between the types of electronic enclosure materials to help select the best option for your project. Finally, note any relevant industry-specific guidance, such as best practices for selecting outdoor telecom equipment enclosures.
