A distribution box needs to be reserved when building a wall
In walls or ceilings constructed of noncombustible material (like drywall or tile), the box can be recessed no more than 1/4 inch from the finished surface. For smaller custom stainless enclosures sizes, wooden blocks can be pre-embedded at. When the distribution box is installed on the wall, it should be fixed with split bolt (expansion bolt). The bolt length is generally the sum of the embedded depth (75-150 mm), the thickness of the box bottom plate, the thickness of the nut and washer, plus the "head allowance" of about 5mm. The distribution box shall be embedded in the wall. When building the wall, the reserved hole shall be about 20mm larger than the length and width of the distribution box. This guide breaks down the actual rules inspectors check — with calculations and real-world examples. You must use approved materials, choose the right size box, and make sure you ground everything correctly.
