UL 50E:2020 PDF Download

UL 50E:2020 standard is a standard that applies to enclosures for electrical equipment installed and used in non-hazardous locations. The standard references the Canadian Electrical Code, the National Electrical Code, and Mexico's Electrical Installations to establish guidelines for different types of enclosures.

The standard covers both indoor and outdoor enclosures with various types, including Types 1, 2, 3, 3X, 3R, 3RX, 3S, 3SX, 4, 4X, 5, 6, 6P, 12, 12K, and 13. It specifically addresses the environmental construction and performance requirements for these enclosures.

However, it is important to note that this standard does not cover the protection requirements against conditions such as condensation, icing, corrosion, or contamination that may occur within the enclosure or enter through conduit or unsealed openings. For those specific requirements, other end-use product standards or guidelines take precedence.
