The organizations listed in
Table 7: Authorities on Electrical Codes
Organization
National Electrical Code (NEC) Classification (USA only)
Recognized authority on safe electrical wiring. Federal,
state, and local governments use NEC standards to
establish their own laws, ordinances, and codes on wiring
specifications. The NEC classification is published by the
National Fire Protection Association (NFPA).
Underwriters' Laboratory (UL) (USA only)
Independent research and testing laboratory. UL evaluates
the performance and capability of electrical wiring and
equipment to determine whether they meet certain safety
standards when properly used. Acceptance is usually
indicated by the words "UL Approved" or "UL Listed."
National Electrical Manufacturing Association (NEMA)
(USA only)
Organization of electrical product manufacturers. Members
develop consensus standards for cables, wiring, and
electrical components.
Electronics Industries Alliance (EIA)
Trade association that develops technical standards,
disseminates marketing data, and maintains contact with
government agencies in matters relating to the electronics
industry.
Federal Communications Commission (FCC) (USA only)
Commission that regulates all interstate and foreign
electrical communication systems that originate in the United
States according to the Communications Act of 1934. The
FCC regulates all U.S. telephone and cable systems.
Equipment Location Considerations
Be aware of the following recommendations for your equipment location:
Be sure that your system is readily accessible for installation and service. See
●
Specifications and Recommendations" on page 33
Use appropriate AC or DC power, power distribution, and grounding for your specific installation.
●
Use a vinyl floor covering in wiring closets or other indoor equipment locations. (Concrete floors
●
accumulate dust, and carpets can cause static electricity.)
Prevent unauthorized access to equipment locations by providing door locks. Install the equipment
●
in a secured, enclosed, and restricted access location, ensuring that only qualified service personnel
have access to the equipment.
Provide adequate overhead lighting for easy maintenance.
●
Be sure that each equipment location has a suitable ground. All equipment racks and equipment
●
installed in the closet should be grounded.
Be sure that all system environmental requirements are met, such as ambient temperature and
●
humidity.
