For a UL-compliant control cabinet, the installation location is of great importance. HazLoc is short for “Hazardous Locations,” which refers to “hazardous locations” as the site of operation. In HazLocs, there is a risk of fire or explosion. Accordingly, when certifying a control cabinet for this area, additional standards and regulations must be followed, including the provisions of NEC 500, which define the classification of hazardous locations and the requirements for electrical equipment in such areas.
