scope:

Applies to all operation of and work activity on, with, or near electrical installations. These installations operate 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 energized or whilst not energized nor charged. Examples are electrically driven excavating machines in quarries or open-cast coal sites. This standard sets out the requirements for the safe operation of and work activity on, with, or near electrical installations. These requirements apply to operational, working and maintenance procedures. This standard sets out the requirements for the safe operation of and work activity on, with, or near electrical installations. These requirements apply to operational, working and maintenance procedures. It applies to all electrical work activities as well as non-electrical work activities such as building work near to overhead lines or underground cables.
