Operation of electrical installations
Working on, with, or near electrical installations implies certain dangers. 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 while energized or while
neither energized nor charged.
The European Standard EN 50110
-
1 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.
The European Standard EN 50110
-
2 is 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
European Standard was prepared.
