Distribution box embedded in wall concealed

A concealed distribution box is embedded in the wall with only the front panel exposed, combining safety, aesthetics, and reliable power distribution.Installation OverviewConcealed distribution boxes are installed embedded in walls, leaving only the front panel visible. When constructing the wall, a reserved hole about 20 mm larger than the box dimensions is required, with a depth equal to the box thickness plus the plastering layer . The box is then fixed with concrete or masonry, ensuring it is firm, horizontal, and vertical, with a vertical deviation not exceeding 3 mm . The edges of the panel should be flush with the wall, and contact points coated with anti-corrosion paint to prevent rust .Materials and ConstructionMost concealed boxes are made from cold-rolled steel, stainless steel, or flame-retardant ABS plastic. Surfaces are treated with anti-rust coatings, phosphating, or electrostatic powder coating to ensure durability and long-term stability when embedded . These boxes typically meet IP40 to IP54 ratings, providing protection against dust and accidental contact, with some models offering IP65 waterproofing for damp areas .Electrical and Safety ConsiderationsInside the box, busbars for neutral (N) and protective earth (PE) lines are installed separately, with clear labeling and numbering. Circuit breakers, leakage protectors, and surge protectors can be mounted on universal installation rails, allowing modular and standardized component installation . Power lines should be connected to terminals according to manufacturer instructions to prevent electric shock during fuse replacement .Aesthetic and Practical BenefitsConcealed distribution boxes provide a clean, integrated look in residential or commercial interiors, hiding wiring while maintaining accessibility for maintenance . The installation height is generally around 1.8 meters for easy operation, with a clear area of 0.8 to 1.2 meters around the box to ensure ventilation and safety . Transparent observation windows on some models allow monitoring without opening the box .SummaryConcealed distribution boxes are ideal for residences, offices, and commercial spaces where aesthetics and safety are priorities. Proper installation involves precise wall embedding, secure fixing, corrosion protection, and correct internal wiring, ensuring both functional reliability and visual integration with the interior design .
