|ICS Code (Plugs, socket-outlets, couplers):||29.120.30|
This standard applies to plugs and socket-outlets, cable couplers and appliance couplers, with a rated operating voltage not exceeding 1 000 V d.c. or a.c. and 500 Hz a.c., and a rated current not exceeding 800 A, primarily intended for industrial use, either indoors or outdoors.
These accessories are intended to be installed by instructed persons (IEC 60050-195:1998, Amendment 1:2001, 195-04-02) or skilled persons (IEC 60050-195:1998, Amendment 1:2001, 195-04-01) only.
The list of preferred ratings is not intended to exclude other ratings.
This standard applies to plugs and socket-outlets, cable couplers and appliance couplers, hereinafter referred to as accessories, for use when the ambient temperature is normally within the range of -25 °C to +40 °C. These accessories are intended to be connected to cables of copper or copper alloy only.
This standard applies to accessories with screwless type terminals or insulation piercing terminals, with a rated current up to and including 32 A for Series I and 30 A for Series II.
The use of these accessories on building sites and for agricultural, commercial and domestic applications is not precluded.
Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the scope of this standard. This standard also applies to accessories intended to be used in extralow voltage installations.
This standard does not apply to accessories primarily intended for domestic and similar general purposes.
In locations where special conditions prevail, for example on board ship or where explosions are liable to occur, additional requirements may be necessary.
This European Standard applies to products intended to be used with cable with metric sizes (mm²) only.
Reference and requirements to AWG and MCM cables and voltages not used in Europe are present in the relevant IEC publication and they are reported in this standard for information only.
See Annex ZB for a list of references to AWG/MCM cables or non-European voltages which are excluded from this standard.
In this standard delete all reference to products of Series II. Values and corresponding requirements listed as Series II ratings are to be considered as "Other ratings".
