7.7 Safety Instructions for installation in Hazardous
(Classified) Location
National Electrical Code is mandatory in order to safeguard person and
property from hazard arising from the use of electricity and in especially when
use electrical equipment in Hazardous (Classified) Location. Therefore the
requirements of the NEC are considered necessary for the safety, compliance
therewith and proper maintenance result in a installation that is adequately free
from hazard.
The NEC is not intended as a design specification or an instruction manual for
untrained person. Chapter 5 Special Occupancies cover the rules for
installation in Hazardous Location.
7.7.1 Basic Instructions for the explosion proof electrical equipment
