625.2 Definitions.
Electric Vehicle. An automotive-type vehicle for on- road use, such as passenger automobiles, buses, trucks, vans, neighborhood electric vehicles, and the like, primarily powered by an electric motor that draws current from a rechargeable storage battery, fuel cell, photovoltaic array, or other source of electric current. For the purpose of this article, electric motorcycles and similar type vehicles and off-road, self-propelled electric vehicles, such as industrial trucks, hoists, lifts, transports, golf carts, airline ground support equipment, tractors, boats, and the like, are not included.
Electric Vehicle Connector. A device that, by insertion into an electric vehicle inlet, establishes an electrical connection to the electric vehicle for the purpose of charging and information exchange. This device is part of the electric vehicle coupler.
Electric Vehicle Coupler. A mating electric vehicle inlet and electric vehicle connector set.
Electric Vehicle Inlet. The device on the electric vehicle into which the electric vehicle connector is inserted for charging and information exchange. This device is part of the electric vehicle coupler. For the purposes of this Code, the electric vehicle inlet is considered to be part of the electric vehicle and not part of the electric vehicle supply equipment.
Electric Vehicle Nonvented Storage Battery. A hermeti- cally sealed battery, comprised of one or more rechargeable electrochemical cells, that has no provision for the release of excessive gas pressure, or for the addition of water or electrolyte, or for external measurements of electrolyte specific gravity.
Electric Vehicle Supply Equipment. The conductors, in- cluding the ungrounded, grounded, and equipment grounding conductors and the electric vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatus installed specifically for the purpose of delivering energy from the premises wiring to the electric vehicle.
Personnel Protection System. A system of personnel protection devices and constructional features that when used together provide protection against electric shock of personnel.
625.3 Other Articles. Wherever the requirements of other articles of this Code and Article 625 differ, the requirements of Article 625 shall apply.
625.4 Voltages. Unless other voltages are specified, the nominal ac system voltages of 120, 120/240, 208Y/120,
240, 480Y/277, 480, 600Y/347, and 600 volts shall be used to supply equipment covered by this article.
625.5 Listed or Labeled. All electrical materials, devices, fittings, and associated equipment shall be listed or labeled.
II. Wiring Methods
625.9 Electric Vehicle Coupler. The electric vehicle cou- pler shall comply with 625.9(A) through (F).
(A) Polarization. The electric vehicle coupler shall be polarized unless part of a system identified and listed as suitable for the purpose.
(B) Noninterchangeabiiity. The electric vehicle coupler shall have a configuration that is noninterchangeable with wiring devices
