One of the biggest challenge companies are facing today is which type of electrical enclosure should they purchase for their engineering project. It is crucial to first determine the different variables and elements that has a big impact on their purchasing decision – location of the engineering project, temperature, possible ingress, etc. With this in mind, we will look at the two most commonly compared electrical enclosure, the NEMA 4X and NEMA 6P.
What is NEMA 4X Electrical Enclosures?
NEMA 4X electrical enclosures are manufactured for both indoor and outdoor use. It gives the users a specific degree of protection given to personnel from having access to hazardous parts. It also gives a certain degree of protection for the equipment housed inside the electrical enclosure against ingress of solid foreign object (such as windblown dust). It also gives protection to equipment from any possible water ingress from rain, sleet, splashing water, snow, ice formation, and hose directed water. Finally, it has corrosion protection and the equipment will be remained undamaged in case an external ice formation will happen.
What is NMA 6P Electrical Enclosures?
NEMA 6P electrical enclosures are manufactured for either outdoor or indoor use. Like NEMA 4X, it also gives protection for personnel from having access to dangerous and hazardous parts. It gives solid ingress protection housed inside the enclosure from falling dirt or other foreign object. It also protects the equipment from having serious damage occurred from water ingress that can cause by hose directed water or water entry caused by prolonged submersion. The enclosure can be submerged in water but only at a limited depth. It also gives corrosion protection and it will be remain undamaged despite of the external ice formation on the enclosure.
