13A 2 Gang Unswitched Socket - Metal Clad Grey

The Knightsbridge MR9000U is a 13A 2-gang unswitched socket housed in a powder-coated metal clad enclosure with integral back box. The unit supplies two standard UK 13A outlets without individual switches, making it suitable for permanent appliance connections in workshops, garages, commercial kitchens and industrial settings where durability and impact resistance are required.

Designed for surface mounting on masonry, concrete, timber stud or metal framework, the metal clad housing eliminates the need for a separate back box — the unit arrives ready to wire and mount. The 45mm projection from the wall gives adequate cable entry space through knockouts in the base and sides of the enclosure. The twin earth terminal ensures compliance with BS 1363-2 standards for earthed socket outlets.

The premium-grade steel construction withstands impacts and abrasion better than standard plastic faceplates, and the powder-coated grey finish resists scratching, chipping and corrosion in environments exposed to dust, moisture and mechanical wear. The unswitched configuration means appliances remain powered at all times unless isolated at the consumer unit or by unplugging, which suits fixed equipment like refrigeration units, security systems and machinery that should not be accidentally switched off.

Product Specification Sheet

Product Manual

Why choose unswitched over switched sockets?

Unswitched sockets remain powered continuously unless isolated at the consumer unit or unplugged. This suits fixed equipment that should not be accidentally switched off, such as refrigeration, security systems, or workshop machinery. In domestic settings, switched sockets are more common for appliances that need local control.

What is the IP rating and where can it be installed?

The IP20 rating means the socket is protected against solid objects larger than 12.5mm but not against moisture ingress. It is suitable for dry indoor locations like workshops, garages and commercial kitchens, but not for outdoor use or environments where water exposure is possible.

Does the metal clad housing require earthing?

Yes. The steel enclosure is Class I, meaning it must be connected to earth via the twin earth terminal. The metal housing itself becomes part of the earthing system, providing additional safety if a fault develops inside the socket.

How is the socket mounted?

The integral back box is designed for surface mounting. Fix the unit to the wall using suitable screws and rawlplugs for masonry, or wood screws for timber stud. Cable entry is via knockouts in the base and sides of the enclosure, which can be removed as needed during installation.
