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.
