This part of IEC 60670 applies to boxes, enclosures and parts of enclosures (hereafter called
“boxes” and “enclosures”) for electrical accessories with a rated voltage not exceeding
1 000 V a.c. and 1 500 V d.c. intended for household or similar fixed electrical installations,
either indoors or outdoors.
Boxes and enclosures complying with this standard are suitable for use at ambient
temperatures not normally exceeding +40 °C, but their average over a period of 24 h does not
exceed +35 °C, with a lower limit of the ambient air temperature of −5 °C.
During the installation the temperature may be outside the above temperature range
according to the classification of the boxes and the enclosures.
This International Standard is intended to apply to boxes and enclosures for electrical
accessories within the scope of IEC technical committee 23.
This standard may be used as a reference document for other IEC technical committees and
subcommittees.
A box or an enclosure which is an integral part of an electrical accessory and provides
protection for that accessory against external influences (for example mechanical impact,
ingress of solid objects or water, etc.) is covered by the relevant standard for such an
accessory.
This standard does not apply to
– ceiling roses;
– luminaire supporting couplers;
– boxes, enclosures and parts of enclosures specifically designed to be used for cable
trunking and ducting systems complying with IEC 61084 and which are not intended to be
installed outside of these systems.

This document applies to residual current monitors for household and similar purposes,
having rated operational voltages and a rated voltage of the monitored circuit not exceeding
440 V AC and rated currents not exceeding 125 A.
NOTE 1 The standard for residual current monitors having rated operational voltages and a rated voltage of the
monitored circuit exceeding 440 V AC is in preparation, as IEC 62020-2.
RCMs are intended to monitor the residual current of the installation and to give a warning if
the residual current between a live part and an exposed conductive part or earth exceeds a
predetermined level.
RCMs covered by this document are not intended to be used as protective devices.
RCMs detect residual currents circulating in an AC circuit (e.g. residual alternating current,
residual pulsating direct current, residual smooth direct current), whether suddenly applied or
slowly rising.
NOTE 2 RCMs for DC systems are under consideration.
This document applies to monitors performing simultaneously the functions of detection of the
residual current, of comparison of the value of this current with the residual operating current
of the device and providing the specified warning signal(s) when the residual current exceeds
this value.
RCMs supplied by internal batteries are not covered by this document.
The requirements of this document apply for standard conditions (see 7.1). Additional
requirements can be necessary for RCMs used in locations having severe environmental
conditions.
RCMs are intended for use in an environment with pollution degree 2 and overvoltage
category III. For an environment with a higher pollution degree, enclosures giving the
appropriate degree of protection are used.
RCMs in compliance with this document are suitable for use in TN, TT, and IT systems.
This document does not cover Insulation Monitoring Devices (IMDs), which are covered by the
scope of IEC 61557-8.
NOTE 3 An RCM is distinguished from an IMD in that it is passive in its monitoring function and only responds to
an unbalanced fault current in the installation being monitored. An IMD is active in its monitoring and measuring
functions in that it can measure the balanced and unbalanced insulation resistance or impedance in the installation
(see IEC 61557-8).

correct engagement.
This document is also applicable to appliance couplers with auxiliary contacts rated for
alternating current, direct current or both, with a total rated current not exceeding 16 A.
This document is also valid for appliance inlets/appliance outlets integrated or incorporated in
appliances.
NOTE 1 Appliance couplers complying with this document are suitable for use in appliances which are used in an
ambient temperature not normally exceeding 25 °C but occasionally reaching 35 °C. However the ambient
temperature surrounding the appliance coupler can exceed these figures and can be declared by the manufacturer.
It is possible that the maximum working ambient temperature for the appliance inlet and for the connector can be
different.
NOTE 2 Appliance couplers dependent on appliance weight for engagement can be subject to spillage of liquid in
normal use. They are classified according to whether protection against liquid spillage is provided, when installed
in accordance with the manufacturer’s installation instructions.
NOTE 3 If appliance inlets according to this document are used with appliances or other equipment which can be
subject to spillage of liquid affecting the appliance inlet when the functioning part of the appliance or equipment is

This document applies to independently mounted switches for appliances (mechanical or
electronic) actuated by hand, by foot or by other human activity, to operate or control
electrical appliances and other equipment for household or similar purposes with a rated
voltage not exceeding 480 V and a rated current not exceeding 63 A.
These switches are intended to be operated by a person, via an actuating member or by
actuating a sensing unit. The actuating member or sensing unit can be integral with or
arranged separately, either physically or electrically, from the switch and involve transmission
of a signal, for example, electrical, optical, acoustic or thermal, between the actuating
member or sensing unit and the switch.
Switches which incorporate additional control functions governed by the switch function are
within the scope of this document.
This document also covers the indirect actuation of the switch when the operation of the
actuating member or sensing unit is provided by a remote control or by a part of an appliance
or equipment, such as a door.
NOTE 1 Electronic switches can be combined with mechanical switches giving full disconnection or microdisconnection.
NOTE 2 Electronic switches without a mechanical switch in the supply circuit provide only electronic
disconnection. Therefore, the circuit on the load side is always considered to be live.
NOTE 3 For switches used in tropical climates, additional requirements can apply.
NOTE 4 Attention is drawn to the fact that the standards for appliances can contain additional or alternative
requirements for switches.
NOTE 5 Throughout this document, the word "appliance" means "appliance or equipment".
