The National Bureau of Standards (NBS) developed the National Electrical Safety Code®
(NESC) in 1913 to bring consistency and
safety to the design, construction, operation,
and use of electric supply and communication
installations throughout the U.S.
The requirements of the original Code were based
upon engineering theory and generally accepted
good practice.
In 1972, IEEE was designated as the secretariat
for the NESC. The NESC continues to be a stronghold
in the U.S. electrical industry and communications
utility field, and serves as the authority on
safety requirements for power, telephone, cable
TV, and railroad signal systems*.
*NESC rules
do not cover installations in mines,
ships, railway rolling equipment, aircraft,
automotive equipment, or utilization wiring
(with some exceptions).
