A specification for explosion proof distribution cabinets must include detailed electrical components for hazardous areas, enclosure materials, and cable entry systems. This brochure was put together carefully in conformance to the current status of standards and regulations. Certification of mechanical (non-electrical) equipment requires an evaluation of the potential ignition sources of the equipment (defined by EN 1127) by performing a thorough ignition hazard assessment (defined by EN 13463-0 in transition to ISO/EN 80079-36. Ex Industries (exindustries) is a global supplier of advanced hazardous area solutions, offering a wide portfolio of certified products including explosion proof electrical boxes, explosion proof junction boxes, explosion proof lighting, intrinsically safe barrier systems, explosion proof cables.
