Summary of NEC Article 500
The NEC Article 500 explains
in great detail the
requirements for the
installation of wiring and
electrical equipment in
hazardous locations. The
purpose of this summary is
for general reference only,
the National Electric Code
along with other applicable
authorities having jurisdiction
over the site should be the
installer’s guidelines when
wiring or installing electrical
equipment in any hazardous
or potentially hazardous
location.
Class I, Division 2 Definition
Class I, Division 2 covers
hazardous locations where
flammable gases, vapors or
volatile liquids are handled
either in a closed system, or
confined within suitable
enclosures, or where
hazardous concentrations are
normally prevented by
positive mechanical
ventilation. Areas adjacent to
Division 1 locations, into
which gases might
occasionally flow, would
also belong to Division 2
(NEC (500-5[b])).
Hazardous Location
Any area where there is the
possibility of explosion and
fire resulting from the
presence of flammable
vapors, liquids or gas, or
combustible dust or fibers.
Summary of NEC Article 505
The NEC also classifies
hazardous locations for
flammable gases and vapors
into zones under NEC 505.
This system is more in line
with the European
Standards, CENELEC and
IEC, with the major
difference being that NEC
505 only classifies gases and
vapors while CENELEC and
IEC also include dusts.
