Description

A range of socket outlets designed for ease of
installation and having all the advantageous
design features of the Logic Plus range. The
2 gang sockets with outboard rockers are of
particular value for use by the infirm and
partially sighted.

Non-standard clean earth sockets are for use
on installations where restricted access is
required and will only accept MK LN647 13A
non-standard plug with T-shaped earth pin.
The sockets have two independent earth
terminals so that they can also be used for
‘clean earth’ installations. K2746 CE WHI has
two independent earth terminals for ‘clean
earth’ installations.

One gang switchsockets, two gang outboard
switchsockets, two gang unswitched sockets
and three gang switchsockets are fitted with
two earth terminals on a common busbar to
provide a double earth facility for use when
installations are to comply with Regulation
607 of BS 7671, IEE Wiring Regulations. These
should be referred to for guidance.

The products can be quickly installed as
replacement for existing 13 amp sockets or in
a new installation.

Fuse carriers
(3 gang switchsocket only)

The fuse carrier is opened by a fast-acting,
screwdriver-operated, worm-drive screw for
ease of replacement.

Round pin sockets

A range of round pin sockets is also available,
switched and unswitched.
