Introduction
The National Electrical Code (NEC), produced by theNational Fire
Protection Association (NFPA), is known as NFPA-70 and is the
“bible” of electrical design and construction. It is developed and written
by a committee of some of the best electricalprofessionals who are
knowledgeable in the safe and effective design, construction, operation,
and maintenance of electrical systems, with input from the industry at
large. It sets forth the minimumstandards by which electrical systems
should be designed and constructed.
While complying with the NEC minimum requirements will ensure
safe and effective electrical system design and operation, gooddesign
practice often dictates that more stringent requirements be met, or
more stringent requirements may be mandated by the local electrical
inspector. Keep in mind that the authority havingfinal jurisdiction for
acceptance of an electrical system’s design and installation is the local
electrical inspector for the project. It may be prudent, therefore, to
involve the local electricalinspector in the early stages of design and
from time to time throughout the design process in order to help him or
her become familiar with the project and your design intent and to see
if thereare any special requirements or possible differences in interpretation
of the NEC, and thus to facilitate a design that will not only be
safe and effective, but will be accepted with no costlysurprises once in
construction.
Interpretations of the NEC can be obtained from the NFPA both formally
and informally, with the latter being the quickest. This is sometimes
needed for clarification ofCode articles that may be subject to
broad interpretation of the Code’s intent.
