Hazardous Location Motors
Certain locations are deemed hazardous because the atmosphere either does or may contain gas, vapor or dust in explosive quantities. The National Electrical Code (NEC®†) divides these locations into Classes and Groups according to the type of explosive agent which may be present. Listed are some of the agents in each classification. For a complete list, see NFPA (National Fire Protection Association) publication 487M. Underwriters’ Laboratories (UL®†) tests motors and other devices for use in explosive atmospheres and publishes a list of those meeting its standards for each Class and Group. Use of UL®† listed devices does not necessarily make an installation conform to the NEC®† or local codes. Consult Chapter 5 of the NEC®† local building codes, OSHA requirements and insurance inspectors for detailed data as to proper procedures.
