Description
A range of socket outlets designed for ease of
installation and having all the advantageous
design features of the Metalclad 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.
One gang switchsockets, two gang outboard
switchsockets and two gang unswitched
sockets 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.
Round pin sockets
A range of round pin sockets is also available,
switched and unswitched.
