Low voltage (LVD) Directive (2014/35/EU)

  Last Official Journal reference

Tuesday 22nd of July 2025

  Description:

Installation couplers intended for permanent connection in fixed installations

  Purpose

This document applies to two-wire, up to five-wire installation couplers, including earth, if provided, with a rated voltage up to and including 500 V AC or DC and a rated connecting capacity up to and including 10 mm2 for permanent connection in electrical installations. Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this document. An installation coupler consists of an installation female connector and an installation male connector for permanent connection not intended to be engaged or disengaged under load nor to be engaged or disengaged other than during first installation or during reconfiguration or maintenance of the wiring system in which installation couplers have been installed. This means that installation couplers are only intended for infrequent use. Installation couplers are not suitable for use in place of socket-outlet systems. Installation couplers are not suitable for use in place of devices for connecting luminaires (DCLs) according to IEC 61995 (all parts) or in place of luminaire supporting couplers (LSCs). Installation couplers complying with this document are suitable for use at ambient temperatures not normally exceeding +40 °C, but their average over a period does not exceed +35 °C, with a lower limit of the ambient air temperature of −5 °C, either for indoor or outdoor use. NOTE 1 Additional tests for use in cold climates are under consideration. NOTE 2 For other temperatures, necessary information can be given in the manufacturer's installation instructions. In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions can be required. NOTE 3 Installation couplers are intended to be installed by instructed or skilled persons.
