The new Low Voltage Directive (2014/35/EU) has now been published. This will come fully into force on 20 April 2016.
The Low Voltage Directive is the oldest of the New Approach Directives and deals with the safety of electrical apparatus. It applies to all apparatus running on (or generating) an electrical supply in the range 50 - 1000 volts a.c. or between 75 and 1500 volts d.c..
There are a small number of exclusions from this Directive, which are generally products covered by more specific directives.
The Directive has both administrative and protective requirements. Administrative requirements include CE marking the product, completing a Declaration of Conformity and compiling a Technical File.
Protection requirements are generally satisfied by assessing the products compliance to various standards. Compliance to the Low Voltage Directive can be self-certified without the need for a notified body.

The Low Voltage Directive 2014/35/EU is one a series of measures introduced under Article 100a of the Treaty of Rome. Article 100a directives all have the primary objective of creating a single European market in goods and services with the objective of providing producers and consumers with the benefits of economies of scale that this offers.
The effect of the Directive has been to introduce identical requirements for the design and certification safety of electrical products in every country within the European Economic Area (EEA).
The Directive was originally enacted in 1973 but was modified in 1993 by Directive 93/68/EEC to include a requirement for CE marking and the creation of a technical file.
In the early years of this century, attempts were made to agree a revised Directive which would include a much more explicit set of safety requirements and remove the lower voltage limits. These proposals proved to be very controversial, and in the end the revision attempt was abandoned. Instead, the Commission introduced 2006/95/EC, a codified directive which brought together the original text of 73/23/EC and its amendments in a single document.
The Directive applies to all apparatus operating on any AC supply between 50 and 1000 volts or DC supply between 75 and 1500 volts. Recent guidance from the European Commission has made it clear that the voltage limits referred to are the supply voltage or any voltage generated which appears at an output terminal, and not voltages generated within and confined internally to the equipment.
Equipment listed in Annex II are excluded from the scope of the Directive:
In the main, these are items which are covered under other more specific directives or which are subject to international legislation outside of the jurisdiction of the EU.
Equipment manufactured for the manufacturer's own use is not excluded from the Directive, but does not need to carry the CE logo. (NB: this is not a universal principle under the CE marking directives - in fact most directives do require equipment made (or imported) for the maker's (or importer's) own use to be CE marked.)
The Directive is implemented in the UK by the Low Voltage Electrical Equipment (Safety) Regulations 1994.
The maximum penalty for the supply of non-compliant equipment is three months imprisonment and/or a £20000 fine. More normally the manufacturer would be required to recall or replace any non-compliant apparatus. The enforcing authorities have the power to suspend or prohibit sale of apparatus for which they have reasonable evidence that it does not comply. Furthermore, because failure to comply with the Regulations may also be a violation of other safety related legislation (e.g. the Health and Safety at Work Act, or the Consumer Protection Act) the penalties may in practice be substantially greater.
The requirements of the Directive can be divided into essential protection requirements and administrative requirements.
The essential protection requirements are contained in Annex 1 to the Directive. In essence they are extremely simple equipment must be safe, it must bear the manufacturer’s name and address and it must be supplied with any necessary instruction to permit it to be used safely.
The administrative requirements are no less straightforward. The manufacturer must:
Because the essential protection requirements are so simple, they aren’t a great deal of use to anyone actually designing or making electrical equipment. Instead, the Directive refers to a list of standards which can be used as the basis of the design. Standards can be used by manufacturers, purchasers, trading standards officers and even courts as a bench mark to consider what, in fact, constitutes 'safe'. Lists of standards can be accessed via the ‘useful links’ section below.
There is no requirement under the Directive for manufacturers to have their products examined and certified by a third party before they can be CE marked. Manufacturers who feel unsure about the requirements of the standards can involve a consultant or Notified Body if they wish, but this is not mandatory under the Directive. Accredited laboratory assessment may be a condition of supply to major retail customers but, again, this is not a requirement of the Directive.
The vast majority of products within the scope of the LVD will also be within the scope of the Electromagnetic Compatibility (EMC) Directive and the RoHS and WEEE directives. The Ecodesign Directive may also apply.
Some electrical products will not be covered by the LVD because they will be covered by other, more specific directives which are mutually exclusive with the LVD. These include the ATEX Directive for equipment used in explosive atmospheres, the R+TTE Directive for radio and telecommunications equipment, the Medical Devices Directive and the Machinery Directive.
The European Commission have a special section on electrical equipment with a great deal of useful information on their EUROPA server. This includes the full text of the directive, lists of the current harmonised standards as well as guidance and interpretative documents.
The best starting point to look for other electrical safety resources is The Safety Link.
As with all CE marking directives, the actual requirements for any piece of equipment under the directive and harmonised standards are complex and dependent on not only the design but also the type of user, the intended use and sometimes even what is claimed in the instructions or sales literature.
