Installation techniques and practices of IEC hazardous area equipment “The nuts and bolts of a good installation”

The world standards for classifying hazardous areas are now closely harmonized. Future projects designs and products will have NEC, CEC and IEC ratings and approvals. This paper begins to sort out the nuts-and-bolts issues that an electrical designer and construction engineer will need to understand in order to properly design, install, wire and terminate an IEC type project. The topics that are addressed include installation techniques, wiring methods with cabling and conduit, lighting practices, and terminating armored cables in metallic and nonmetallic enclosures. The end product serves as a preliminary guide for engineers who need a thorough reference to design and install electrical equipment in areas outside of North America
