What Is a Flush-Mounted Electrical Distribution Box Enclosure?

A Flush-Mounted Electrical Distribution Box Enclosure is a type of enclosure specifically designed for installation within walls or panels. After installation, the enclosure surface is flush with the wall, with only an openable door or panel visible.

Specifically, this type of distribution box needs to be pre-embedded in the wall, partition, cabinet panel, or decorative surface. Installation holes must be pre-drilled during construction. The enclosure can be made of cold-rolled steel, galvanized steel, or stainless steel. For indoor applications, the protection rating is generally IP20–IP40; for use in damp areas (such as bathrooms or basements), an IP54 embedded waterproof model is available.

FAQ

Q: How should the wall opening size be calculated when installing a concealed electrical box?

A: The opening size should be based on the actual length, width, and depth of the box's bottom. It's generally recommended to leave a 5-10mm gap around the box's perimeter to allow for leveling and filling with cement mortar. Choosing Shangming as your manufacturer will also provide you with complete installation advice, including dimensional data for installation, in addition to customization.

Note: The panel size is usually larger than the back box; this extra edge will automatically cover the opening gap, so you don't need to leave space for the panel.

Q: Can a concealed electrical box be installed on a plasterboard partition wall?

A: Yes, but specific accessories are required. For concrete or brick walls, it's usually fixed directly with cement.

For plasterboard, you'll need to select a special extended fixing bracket or side fastener to lock the box onto the joists. Shangming can provide corresponding installation accessories according to your project requirements.

Q: What if the wall plaster thickness is uneven, causing the box to be buried too deep or too shallow?

A: Our recessed distribution box enclosure is designed with this in mind, featuring adjustable internal rails and mounting plates. Even if the box is embedded slightly deep in the wall, you can push the internal components outwards using the adjusting bolts.

Q: How is the fire resistance of the recessed distribution box?

A: Compared to plastic concealed boxes, our all-metal (carbon steel/galvanized steel/stainless steel) concealed boxes offer superior flame retardant properties.

Metal does not burn in the event of an electrical fire, effectively preventing the spread of fire into the wall. For commercial real estate and public buildings, all-metal concealed boxes are a mandatory requirement for fire safety inspections.
