  • SCOPE

    1 Scope

    1.1 This Standard covers conductive electric vehicle (EV) supply equipment with a primary source voltage of 600 V ac or less, with a frequency of 50 or 60 Hz, and intended to provide ac power to an electric vehicle with an on-board charging unit. This Standard covers electric vehicle supply equipment intended for use where ventilation is not required.

    1.2 With reference to 1.1, the following list of examples of electric vehicle supply equipment are included in this Standard:

    a)    EV Cord Sets – Rated 125 Vac maximum, 16 A maximum, intended for indoor and outdoor use;

    b)    Fastened in place EV Charging Stations – Rated 250 Vac maximum, 40 A maximum, intended for indoor or outdoor use;

    c)    Fixed in place EV Charging Stations – Rated 600 Vac maximum, intended for indoor or indoor/outdoor use; and

    d)    Fixed in place EV Power Outlet – Rated 600 Vac maximum, intended for indoor or indoor/outdoor use.

    For Mexico, use 127 Vac where 120 or 125 Vac is referenced in this Standard. In Canada and the United States, this does not apply.

    1.3 The products covered by this Standard are intended for use in accordance with the Installation Codes in Annex A, Ref. No.1.

    1.4 This Standard does not cover cord sets or power supply cords for applications other than EV charging cord sets. For cord sets and power supply cords not covered by this Standard, refer to Annex A, Ref. No. 2 and No. 3.

    1.5 With reference to 1.2, this Standard does not cover electric vehicle charging equipment. For EV charging equipment not covered by this Standard, refer to Annex A, Ref. No. 4.

    1.6 This Standard does not cover electric vehicle connectors. For electric vehicle connectors not covered by this Standard, refer to Annex A, Ref. No. 5

    1.7 This Standard does not cover regular-use power outlets. For regular-use power outlets not covered by this Standard, refer to Annex A, Ref. No. 6.

    1.8 This Standard does not cover equipment intended for wireless power transfer, which may also be designated as wireless charging, inductive charging, magnetic resonance charging, or any other similar designation indicating the transfer of power from the EVSE to the vehicle through other than a conductive connection.
