This course is an overview of electrical wiring methods and the materials used for installations in hazardous locations.  This lesson describes the various hazardous location classifications and the wiring methods and materials used to provide a proper and safe installation. 

 

Being able to install the wiring for hazardous areas requires an understanding of basic area classifications and the materials that are allowed to be used in each.  This knowledge is essential when choosing the wiring, conduits, fittings and seals for new construction and remodeling projects in hazardous areas where flammable gases, liquids, vapors, dust and fibers will be present.
