CLC/BTTF 62-3 - Operation of electrical installations

The European Standard EN 50110 series consists of two parts: - the first part, EN 50110 1, contains minimum requirements valid for all CENELEC countries and some additional informative annexes dealing with safe working; - the second part, prEN 50110 2, is a set of national annexes (one per each member country) which specify either additional safety requirements actually in force or national supplements to the minimum requirements set by EN 50110-1. The national annexes are the responsibility of an have to be maintained by the respective member country. National Committees shall notify CENELEC of any changes needed to their national annex.

This document 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 commonly 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 document 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 such as building work near to overhead lines or underground cables as well as electrical work, when there is a risk of electrical danger. This document 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 document 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 document 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.

The standard consists of two parts. The first part EN 50110-1 contains Minimum Requirements valid for all CENELEC countries and some additional informative annexes dealing with safe working. The second part EN 50110-2 consists of a set of normative annexes (one per country) which specify either the present safety requirements or give the national supplements to these Minimum Requirements at the time when this standard was prepared. The national annexes (if any) are summarized by the respective member country. National Committees shall notify CENELEC of any changes needed to their national annex
