When you are asking whether to power your emergency lights by a generator, you are asking whether to feed the emergency lighting. IF it is fed from a generator then, that conduit and wiring is inherrently article 700 Legally required emergency systems.
A. General
700-1. Scope. The provisions of this article apply to the electrical safety of the
installation, operation, and maintenance of emergency systems consisting of circuits
and equipment intended to supply, distribute, and control electricity for illumination
or power, or both, to required facilities when the normal electrical supply or system
is interrupted.
Emergency systems are those systems legally required and classed as emergency
by municipal, state, federal, or other codes, or by any governmental agency having
jurisdiction. These systems are intended to automatically supply illumination or
power, or both, to designated areas and equipment m the event of failure of the
normal supply or in the event of accident to elements of a system intended to supply,
distribute and control power and illumination essential for safety to human life.
(FPN No. 1): For further information regarding wiring and installation of
emergency systems in health care facilities, see Article 517.
(FPN No. 2): For further information regarding performance and maintenance of
emergency systems in health care facilities, see Standard for Health Care Facilities,
NFPA 99-1999.
(FPN No. 3): Emergency systems are generally installed in places of assembly
where artificial illumination is required for safe exiting and for panic control in
buildings subject to occupancy by large numbers of persons, such as hotels,
theaters, sports arenas, health care facilities, and similar institutions. Emergency
systems may also provide power for such functions as ventilation where essential to
maintain life, fire detection and alarm systems, elevators, fire pumps, public safety
communications systems, industrial processes where current interruption would
produce serious life safety or health hazards, and similar functions.
(FPN No. 4): For specification of locations where emergency lighting is considered
essential to life safety, see Life Safety Code, NFPA 101-2000.
(FPN No. 5): For further information regarding performance of emergency and
standby power systems, see Standard for Emergency and Standby Power Systems,
NFPA 110-1999.
All I'm asking or saying is who said what he has is an Emergency System and must be installed to article 700 of the NEC.
(See in bold above)
Can the original poster come back and tell us he has been told by any of the above he has an emergency system covered by article 700?
