Code of Practice for the Electricity (Wiring) Regulations - 2009 Edition

(b) For steel surface conduit installations, the supplementary bonding
conductors should be terminated at the nearest conduit or conduit
box forming an integral part of the conduit installation.
(c) (i) For concealed steel conduit installations, the supplementary
bonding conductors should be terminated at a copper earthing
terminal fitted inside a metal box forming an integral part of the
conduit installation. For access to the concealed conduit, an
arrangement similar to a telephone cord outlet is acceptable.
(ii) The metal conduit box should be located as near as possible to
the bonding position and the exposed part of the
supplementary bonding conductor should be made as short as
possible.
25E Installation of Socket Outlets
(a) Wall-mounted socket outlets should be installed with a minimum clear
height of 150 mm from floor and 75 mm from surface top measured
from the bottom of the socket outlet.
(b) Socket outlets installed on floor surface should be suitably protected from
ingress of water and from mechanical damage.
(c) Socket outlets for household or similar use should be of shuttered
type.
(d ) A socket outlet should be installed as far away as practicable from water
tap, gas tap or cooker in order to avoid danger.

Notes: (1) The spacings tabulated above assume that the conduit is not exposed to
mechanical stress other than that due to the weight of the enclosed cables, the
conduit and fittings.
(2) The above figures do not apply to a conduit used for supporting luminaires or other
equipment.
