Electrical installations of buildings - Part 1: Scope, object and fundamental principles

Scope

Applies to electrical installations such as those of:
a)residential premises
b)commercial premises
c)public premises
d)industrial premises
e)agricultural and horticultural premises
f)prefabricated buildings
g)caravans, caravan sites and similar sites
h)construction sites, exhibitions, fairs and other temporary
installations.
i)marinas and pleasure craft

Covers:
a)circuits supplied at nominal voltages up to and including 1000 V
a.c. or 1500 V d.c.
b)circuits, other than the internal wiring of apparatus, operating
at voltages exceeding 1000 V and derived from an installation
having a voltage not exceeding 1 000 V a.c., e.g. discharge
lighting, electrostatic precipitators
c)any wiring not specifically covered by the standards for
appliances
d)all consumers' installations external to buildings;
e)fixed wiring for telecommunication, signalling, control and the
like (excluding internal wiring of apparatus)
f)the extension or alteration of the installation and also parts of
the existing installation affected by the extension or alteration.

Does not apply to:
a)electric traction equipment
b)electrical equipment of motor vehicles
c)electrical installations on board ships
d)electrical installations in aircraft
e)public street-lighting installations
f)installations in mines
g)radio interference suppression equipment, except in so far as it
affects the installation's safety
h)electric fences
i)lightning protection of buildings

Note: -Atmospheric phenomena are however covered, in so far as
effects on the electrical installations are concerned (e.g. with
respect to selection of lightning arresters).

Contains the rules for the design and erection of electrical
installations so as to ensure safety and proper functioning for the
use intended.

Note: -For identification of insulated and bare conductors by
colours, see IEC 60446.
