2 Units of Measurement 2.1 The values given in SI (metric) units shall be normative. Any other values given shall be for information purposes only. 3 Components 3.1 Except as indicated in 3.2, a component used as a part of a unit covered by this Standard shall comply with the requirements for that component. 3.2 A component is not required to comply with a specific requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this Standard, or b) Is superseded by a requirement in this Standard. 3.3 A component shall be used in accordance with its rating established for the intended conditions of use. 3.4 Specific components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions. 4 Normative References 4.1 Where reference is made to any Standard, such reference shall be considered to refer to the latest editions and revisions thereto available at the time of printing, unless otherwise specified.
5.4 CHARGING CIRCUIT INTERRUPTING DEVICE (CCID) – A device that continuously monitors the differential current among all of the current-carrying line conductors in a grounded system and rapidly interrupts the circuit under conditions where the differential current exceeds the ground-fault trip threshold of the charging circuit interrupting device. The device is identified by the letters CCID followed by the differential trip current rating of either 5 or 20 mA. 5.5 CHARGING STATION, MOVABLE – A device used to provide power to an on-board charger. The device is cord connected and intended to be occasionally moved from charging location to another charging location. 5.6 CHARGING STATION, PERMANENT – A device used to provide power to an on-board charger. The device is permanently wired and fixed in place to the supporting surface, a wall, a pole, or other structure. 5.7 CONTROL CIRCUIT – A circuit that carries electric signals but not main power current. 5.8 COMMERCIAL GARAGE – A facility, or portion of a facility, used for the repair of internal combustion engine vehicles, in which the area may be classified due to vapors of flammable liquids (gasoline) being present. 5.9 CORD SET, PORTABLE – An EV cord set that is intended for indoor or outdoor use, and is intended to be carried from charging location to charging location and is transported in the vehicle when not in use. This type of cord set will be subject to changing environmental conditions and all foreseeable abuses. See 6.1 .1 .
