Plugs and socket outlets

CATEGORY: Electrical appliances and equipment

Product definition

This factsheet applies to plugs and socket-outlets intended for use in domestic electric installations.

Plugs and socket outlets are used for the connection of electrical and electronic products to the mains electricity supply.

A plug is an accessory intended for frequent use by consumers, having pins designed to engage with the contact of a socket-outlet, also incorporating means for the electrical connection and mechanical retention of one flexible cable.

A socket-outlet is an accessory intended for frequent use by consumers, having socket contacts designed to engage with the pins of a plug and having terminals or terminations for the connection or a cable.

Socket-outlets can be fixed or portable
Socket-outlets can also be multiple, i.e. a combination of two or more socket-outlets.
Socket-outlets may be combined with outlets for low power circuitry, e.g. antenna or data cables
Socket-outlets may also employ additional functions such as power-line communication or low voltage power supply (e.g. via a USB outlet).

NB: For this product category, certificates are only recommended as well as involving a third party laboratory in the conformity assessment.

Common risks of plugs and socket outlets

The most common risks identified in this product sector are set out below.

1. Electrical risks

Electrical, magnetic or electromagnetic disturbances emitted from the electronics can adversely affect persons, domestic animals, property and nearby electrical products.

2. Thermal risks:

Hot surfaces can cause burns.
Poorly insulated or fixed wires or substandard components can short circuit and create arcs or overheating, leading to fire.

3. Mechanical risks:

High sound pressure levels can cause damage to hearing.
Heavy products that are unstable can fall over and cause injuries.
Poor mechanical construction so that heavy equipment intended to be hung on a wall can fall down and cause injuries.
Surfaces, edges, corners with sharp edges, or other flaws can cause injuries.
Rotating parts can cause injuries while spinning.

4. Optical risks

Optical radiation (primarily lasers or blue light sources in the product) can cause damage to sight.

Further risks if the plug or sockets contains batteries

Short-circuits in the internal wiring or electronics can cause overheating of batteries or explosion, leading to leakage of dangerous chemicals.
Accessible small batteries (AAA or smaller) can be put in the mouth and swallowed, causing choking and damage to the gastrointestinal tract.

See further risks

This is a list of examples of common risks. However, the manufacturer has to carry out an assessment of the plug or socket outlet that covers all relevant risks that may be associated with the product and actions taken to mitigate these risks where possible. A general definition of risk and its relationship to hazards can be found in the factsheet on Risk management.

Examples of dangerous products

Specific examples of measures taken against dangerous plugs and socket outlets offered for sale in the European Union are available on the Safety Gate website. Type ‘plug’ or ‘socket’ into the free text search box (but without the quotation marks) and select the ‘electrical appliances and equipment’ Product Category to view notified examples. A better understanding of mistakes made in the safety assessment on the plug or socket outlet, or its manufacture can help avoid their repetition.

Main applicable legislation

These products are governed mainly by the Low Voltage Directive (LVD). The Directive lays down the safety criteria that all plugs and socket outlets must meet before they can be marketed in the EU. Plugs and socket outlets must comply with the essential safety requirements set out in this Directive. More specific details can be found here.

In addition, if the electrical appliance and equipment is capable to communicate wirelessly (e.g. incorporates Bluetooth or Wi-Fi), it should meet the requirements of the Radio Equipment Directive.

Please also check the factsheet for Power Supplies, Chargers and Adaptors for safety requirements for the external power supply.

All other products (with a voltage rating below 50 V AC or 75 V DC) and risks not covered by the LVD, are governed by the General Product Safety Directive (GPSR). The Directive lays down that only safe consumer products can be marketed in the EU. Plugs and socket outlets must comply with the general safety requirement set out in this Directive. More specific details can be found here.

Applicable standards

“European standards” exist in the EU for plugs and socket outlets. It is important to note that the latest edition of the standard referenced in the OJEU (including any amendments) applies.
It is important to note that the latest edition of the standard referenced in the OJEU (including any amendments) applies.

Note: The following site of CEN CENELEC (the European standardisation organisation) provides links to the national standardisation bodies’ websites. In addition, the China Standards Information Services Network can be used to access European standards.

The following standards apply to plugs and socket outlets (and others may apply in specific circumstances):

IEC 60884-1:2002+A1:2006+A2:2013

This standard lays down safety requirements for plugs and socket outlets for household and similar purposes. It is not harmonised and therefore compliance does not offer the presumption of conformity with European legal requirements.

However, the standard series covers other safety issues and manufacturers are strongly advised to consult the whole standard.

Other legislation of relevance:

The following summarises some further key applicable laws:

EMC (Electromagnetic Compatibility) – lays down requirements for emission of electromagnetic disturbances to the environment and immunity to electromagnetic disturbances in the surrounding environment. Electromagnetic immunity and disturbances for products incorporating a communications device are dealt with under the Radio Equipment Directive.
RoHS 2 Directive (Restriction of Hazardous Substances) – restricts the use of certain substances and chemicals in electrical and electronic equipment
Ecodesign regulations – establishes ecodesign requirements for energy-related products
Energy labelling regulations – establishes the requirements and criteria for energy labelling of energy-related products
Waste Electrical and Electronic Equipment (WEEE) – establishes rules for treating of waste electrical and electronic equipment, to contribute to sustainable production and consumption
Please note that every product must be safe for the consumers according to the General Product Safety Directive (GPSR), even if it falls outside of the voltage limits specified in the Low Voltage Directive.

Additional requirements if the product contains batteries

The Battery Directive Batteries commonly contain hazardous substances such as mercury, cadmium and lead, which when incinerated or placed in landfill can present a risk to the environment and human health. As a result, this Directive sets maximum quantities for certain chemicals and metals in certain batteries and creates rules covering matters such as labelling, documentation and marking requirements

See additional requirements

Mandatory labelling & warnings

The following are obligatory:

CE Marking is obligatory for all plugs and socket outlets that fall within the scope of the LVD. Before marking the plug or socket outlet with the CE mark, the manufacturer needs to identify all the applicable legal requirements, verify the conformity of the plug or socket outlet with these requirements, compile a technical documentation that evidences this and create a written declaration of conformity. When this has been done, he should affix the CE mark on the product. Refer to the factsheet on CE marking.
Information on the manufacturer and the importer is obligatory.
The crossed-out wheel bin is obligatory for all electronics to indicate that it must be disposed of according to the rules for handling of waste from electronic and electrical equipment.

Safety warnings and instructions are obligatory for many types of plug and socket outlet to draw attention of users to risks and how to avoid injury.

General safety requirements

To ensure that manufacturers produce only safe plugs or socket outlets there are also a range of general requirements to be fulfilled. These are explained in the following factsheets and need to be read in conjunction with this factsheet:
