IEC 62208 pdf download Empty enclosures for low-voltage switchgear and controlgear assemblies – General requirements
This International Standard applies to empty enclosures，prior to the incorporation ofswitchgear and controlgear components by the user, as supplied by the enclosuremanufacturer.
This standard specifies definitions，classifications，characteristics and test requirements ofenclosures to be used as part of switchgear and controlgear assemblies in accordance with theIEC 60439 series, the rated voltage of which does not exceed 1 000 V a.c. at frequencies notexceeding 1 000 Hz,or 1 500 v d.c. and suitable for general use for either indoor or outdoorapplications.
This standard does not apply to enclosures，which are covered by other specific productsstandards (e.g.IEC 6067o).
Compliance with the safety requirements of the applicable product standard is the responsibilityof the final assembly manufacturer.
NOTE This standard may serve as a basis for other technical committees.

NOTE Throughout this standard, the word enclosure is used for empty enclosure.
protected s pace
internal space or portion of the internal space of the enclosure as specified by the manufacturer intended for the mounting of switchgear and controlgear for which the specified protection is provided by the enclosure
external part of the enclosure
hinged or sliding cover
separate internal accessory of the enclosure intended for the mounting of electrical components
cable gland plate
removable accessory of the enclosure, intended for securing and sealing of cables, conductors and conduits at their point of entry
