    Abstract - (Show below) - (Hide below)

    IEC 60670-24:2011 applies to enclosures and parts of them for housing protective devices and other power dissipating electrical equipment intended to be used with a rated voltage not exceeding 400 V and a total incoming load current not exceeding 125 A for household and similar fixed electrical installations. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. The following major changes from the first edition are introduced:
    - new definition for basic, general purpose enclosures (GP enclosure) and enclosures for pre-determined equipment (PD enclosure);
    - new classification and marking for general purpose enclosure (GP enclosure) and enclosure for pre-determined equipment (PD enclosure);
    - required data for instruction sheet and/or documentation according to the type of enclosure;
    - adequate space to allow mounting and connection of the accessories (fully equipped) as declared by the manufacturer;
    - requirements for general purpose enclosure (GP enclosure) as in Clause 101;
    - requirements for enclosure for pre-determined equipment (PD enclosure) as in Clause 102;
    - instructions to be given by the manufacturer of the GP enclosure to the installer how to integrate accessories and example of calculation given in Annex AA;
    - instructions to be given by the manufacturer of the PD enclosure to the installer how to integrate accessories given in Annex BB.

    This publication is to be read in conjunction with IEC 60670-1:2002.
