This Technical Report is intended to explain the “Nonincendive Equipment” protection technique and to clarify the associated terminology. Clarification of the term “Nonincendive Equipment” is very important since it has been used in two different ways. When electrical equipment is used in locations in which fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitible fibers or flyings, the National Electrical Code (NEC), ANSI/NFPA 70 requires special precautions to be taken in equipment construction and installation to minimize risks of fire and explosions. A location in which the fire or explosion hazard exists infrequently and for short periods is designated as a Division 2/Zone 2 location. One suitable protection technique for a Division 2/Zone 2 location is “Nonincendive Equipment”. This Technical Report also addresses field wiring for Division2/Zone 2 locations.
