EN 50110-1:2013

Operation of electrical installations - Part 1: General requirements

This European Standard is applicable to all operation of and work activity on, with, or near electrical installations. These are electrical installations operating at voltage levels from and including extra-low voltage up to and including high voltage. This latter term includes those levels referred to as medium and extra-high voltage. These electrical installations are designed for the generation, transmission, conversion, distribution and use of electrical power. Some of these electrical installations are permanent and fixed, such as a distribution installation in a factory or office complex, others are temporary, such as on construction sites and others are mobile or capable of being moved either whilst energised or whilst not energised nor charged. Examples are electrically driven excavating machines in quarries or open-cast coal sites. This European Standard sets out the requirements for the safe operation of and work activity on, with, or near these electrical installations. The requirements apply to all operational, working and maintenance procedures. They apply to all non-electrical work activities such as building work near to overhead lines or underground cables as well as electrical work activities, when there is a risk of electrical danger. This European Standard does not apply to ordinary persons when using installations and equipment, provided that the installations and equipment comply with relevant standards and are designed and installed for use by ordinary persons. This European Standard has not been developed specifically to apply to the electrical installations listed below. However, if there are no other rules or procedures, the principles of this European Standard could be applied to them – on any aircraft and hovercraft moving under its own power, (these are subject to International Aviation laws which take precedence over national laws in these situations); – on any sea going ship moving under its own power, or under the direction of the master, (these are subject to International Marine laws which take precedence over national laws in these situations); – electronic telecommunications and information systems; – electronic instrumentation, control and automation systems; – at coal or other mines; – on off-shore installations subject to International Marine laws; – on vehicles; – on electric traction systems; – on experimental electrical research work.

Introduction
There are many national laws, standards and internal rules dealing with the matters coming within the
scope of EN 50110 and these practices have been taken as a basis for this work.
EN 50110 consists of two parts:
– Part 1 of EN 50110 contains minimum requirements valid for all CENELEC countries and some
additional informative annexes dealing with safe working on, with, or near electrical installations;
– Part 2 of EN 50110 consists of a set of normative annexes (one per country) which either specify the
present safety requirements or give the national supplements to these minimum requirements.
This concept is still believed to be a decisive step to the gradual alignment in Europe of the safety levels
associated with the operation of, work activity on, with, or near electrical installations. This document
acknowledges the present different national requirements for safety. The intention is, over the course of
time, to create a common level of safety.
Even the best rules and procedures are of no value unless all persons working on, with, or near electrical
installations are thoroughly conversant with them and with all legal requirements and comply strictly with
them.
1 Scope
This European Standard is applicable to all operation of and work activity on, with, or near electrical
installations. These are electrical installations operating at voltage levels from and including extra-low
voltage up to and including high voltage.
This latter term includes those levels referred to as medium and extra-high voltage.
These electrical installations are designed for the generation, transmission, conversion, distribution and
use of electrical power. Some of these electrical installations are permanent and fixed, such as a
distribution installation in a factory or office complex, others are temporary, such as on construction sites
and others are mobile or capable of being moved either whilst energised or whilst not energised nor
charged. Examples are electrically driven excavating machines in quarries or open-cast coal sites.
This European Standard sets out the requirements for the safe operation of and work activity on, with, or
near these electrical installations. The requirements apply to all operational, working and maintenance
procedures. They apply to all non-electrical work activities such as building work near to overhead lines or
underground cables as well as electrical work activities, when there is a risk of electrical danger.
This European Standard does not apply to ordinary persons when using installations and equipment,
provided that the installations and equipment comply with relevant standards and are designed and
installed for use by ordinary persons.

SIST EN 50110-1 : 2013
NACIONALNI UVOD
Standard SIST EN 50110-1 (sl), Obratovanje električnih postrojev – 1. del: Splošne zahteve, 2013,
ima status slovenskega standarda in je enakovreden evropskemu standardu EN 50110-1 (en),
Operation of electrical installations – Part 1: General requirements, 2013.
NACIONALNI PREDGOVOR
Evropski standard EN 50110-1:2013 je pripravila evropska delovna skupina CLC/BTTF 62-3
Obratovanje električnih postrojev. V tem delu so podani minimalne zahteve, ki veljajo v vseh državah
CENELEC, in nekateri informativni dodatki o varnem delu na električnih postrojih ali v njihovi bližini.
Drugi del je zbirka posebnih nacionalnih določil posameznih držav članic ter zajema vse njihove
posebne tehnične in zakonodajne zahteve.
Slovenski standard SIST EN 50110-1:2013 je prevod evropskega standarda EN 50110-1:2013. V
primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni evropski
standard v angleškem jeziku. Slovensko izdajo standarda je pripravil tehnični odbor SIST/TC DPN
Delo pod napetostjo.
Tehnični odbor SIST/TC DPN je bil ustanovljen leta 2007, ko je v podjetjih postala prisotnejša potreba
po delu pod napetostjo. Pred tem so slovenski strokovnjaki spremljali to področje v okviru tehničnega
odbora za nizkonapetostne inštalacije, SIST/TC ELI. Pri elektrotehniški terminologiji so prednostno
uporabljeni izrazi iz najnovejših prevodov ustreznih poglavij mednarodnega elektrotehniškega
slovarja, posebej SIST IEC 60050-826:2006, Mednarodni elektrotehniški slovar – 826. del: Električne
inštalacije. Prevodi vseh definicij v standardu SIST EN 50110-1:2013 in raba izrazov, ki se nanašajo
na področje električnih postrojev, so poenoteni s tem prevodom slovarja.

Na področju varstva pri delu je mnogo izrazov vzetih iz obstoječe zakonodaje področja, predvsem iz
Pravilnika o varstvu pri delu pred nevarnostjo električnega toka, Uradni list RS, št. 29/1992.

Odločitev za izdajo tega standarda je v aprilu 2013 sprejel SIST/TC DPN.

ZVEZA Z NACIONALNIMI STANDARDI
