Key Features & Typical Use
The Positions in a Property That Need Protection
An institution that offers lodging that is only for a short period possesses some sites where water or steam can arrive at a socket face. The bathroom, housekeeping cupboards, pantry, and maintenance corridors. Those places have always been equipped with covers and either reconstruction or erection of a new building implies that the same plates should be mounted there.
Protection at the Times It Is Needed
The cover of the socket face is closed when no device is plugged in. It is at this time dust and moisture are able to penetrate the connection. The operation is done at an angle and rests against the device’s body making it possible to use the vacuum cleaner or hair dryer without an interruption.
One Plate Format through Front and Back of House
Overall, the front-of-house operations and back-end operations look like they utilize leftover equipment and assets… which would explain why one aisle might be filled with different kinds of trays. It helps in the upkeep and management of the spare parts when both the curly plug and the user devices are housed in the same 86 x 76 mm panel.
Specified by Position, Not by Building
The usage of covered sockets is limited to certain locations where they are not required to be mounted in dry locations. The covered socket also consists of standard and charging modules within the same module, thus allowing for covered sockets to be combined in suitable locations without the need of altering the existing project.

SD3B-022 – Covers Where Water, Steam and Cleaning Reach the Wall
The use of covered sockets is a reaction to different situations rather than simply a matter of design: steam in bathrooms, water on a service floor, cleaning agents in a housekeeping area, and so on. In a property, the specific conditions appear in the same locations on each floor. Hence, the covered socket is included as a standard item in the fit-out program.
Using the wide panel form ensures that the socket looks the same as those in the guest room and corridors although located in a service area. It also reduces the number of spare varieties of plates in a hospitality establishment while ensuring that the replacement in year 5 matches the original supplied products. The French equivalent of the wide panel design is SD3B-023.

Frequently Asked Questions
Where are covered sockets used in a hotel?
You can find the locations of wall outlets in washrooms, housekeeping cabinets, kitchens, and service areas anywhere there is an unprotected socket in a wet area, in all the floors of a building.
What protection does the cover provide?
When the appliance is not being used, it will cover the female socket in order to keep out dust, dirt, liquid and cleaning fluids. During usage, it gets up and rests on the plug mould; hence, the device can be used normally.
Is it the same as a waterproof socket?
The cover lends effective protection from dust and splashing of water at the socket. However, if the situation requires uninterrupted contact with weather elements or water streams, it should be evaluated according to local regulations and we will make recommendations for the proper assembly.
Why use the same panel format in service areas?
This is because the property only needs one plate instead of three as a spare and uses another plate of the same type as a replacement years later. It also ensures a uniform identity of the front and back of house throughout the passageways.
Is a French format version available?
Indeed, SD3B-023 is the French-Standard Type E socket with the corresponding configuration provided on the identical 86 x 76mm panel, making it possible for a French standard issue to state that it requires covered outlets in its own socket specification.
Can covered and plain sockets be ordered on one schedule?
Indeed, this is the common pattern where there are terminals covered for various functions, normal or charging terminals for other uses, all within the same panel. MOQ for the products will be determined when a quotation is made.
