Nonincendive field wiring circuits must be wired in accordance with the
National Electrical Code (NEC), NFPA 70 , article 501.
WARNING - EXPLOSION HAZARD – SUBSTITUTION OF ANY COMPONENTS MAY IMPAIR SUITABILITY FOR
HAZARDOUS LOCATIONS OR EXPLOSIVE ATMOSPHERES.
WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED
OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS.
*) Notes:
The nonincendive field wiring circuit concept allows interconnection of nonincendive field wiring apparatus and
associated nonincendive field wiring apparatus using any of the wiring methods permitted for unclassified locations when
certain parametric conditions are met.
