NEMA 4X junction boxes work for protecting electronics and electrical systems in various harsh indoor and outdoor environments. Learn about the requirements and uses of a NEMA 4X junction box to determine if you need one for your application.
What Makes an Enclosure NEMA 4X Rated?
The National Electrical Manufacturers Association (NEMA) maintains a rating system that outlines the standards electrical enclosures must meet in certain environments.
Each NEMA rating pertains to particular features and operating environments. The NEMA 4X junction box is a variation of the NEMA 4 box type, which protects against water ingress in either indoor or outdoor applications. Like NEMA 4 junction boxes, NEMA 4X junction boxes protect against rain, ice, snow, and dirt, and are suitable for indoor and outdoor environments. However, NEMA 4X junction boxes provide superior corrosion resistance. Thus, they are used more frequently in marine, waste processing, and water treatment facilities.
Applications of NEMA 4X Junction Boxes
There are numerous applications for NEMA 4X junction boxes, with most of them being in outdoor spaces to protect sensitive components from corrosion and harsh weather conditions.
Protecting Equipment From Corrosion and Inclement Weather
Many outdoor environments experience harsh weather that might cause gradual wear and tear to junction boxes. NEMA 4X junction box designs hold up in snow, ice, and rain. Additionally, they can protect against corrosion from exposure to salt air or water.
Preventing Water Ingress in Washdown Environments
Similar to NEMA 4 boxes, the NEMA 4X junction box is capable of keeping water from entering enclosures in environments with frequent exposure to high-pressure water streams. NEMA 4 box designs can handle streams from a 1” nozzle of up to 65 gallons per minute for at least five minutes. NEMA 4X boxes feature added corrosion resistance to maximize their longevity in corrosive environments, with the ability to block hose-directed and splashing water.
