Electrical recessed box Kopos KEZ-3 KB for insulation, 3-socket configuration 230×100×250 mm

The Kopos KEZ-3 KB recessed electrical box for insulation is designed for installation within insulated façades and wall insulation systems. With internal space for three socket modules and external dimensions of 230×100×250 mm, it houses wiring connections and outlets inside the thermal insulation layer while maintaining alignment with the finished surface. The box is intended to provide organized cable routing and secure mounting for residential or commercial electrical installations where outlets need to be integrated into insulated walls.

Advantages

The unit allows concealed mounting of three socket modules in insulated walls, reducing thermal bridging and protecting connections from external conditions. Its dimensions suit common insulation thicknesses and enable straightforward positioning and fastening within the insulation material. Constructed from materials suitable for installation in building insulation layers, the box facilitates tidy cable management and stable support for electrical modules.

Suitable for

• Installation of three electrical sockets in insulated façades and external wall insulation systems
• Residential and commercial projects requiring flush-mounted outlets within thermal insulation
• Renovation works where existing insulation is modified to add or relocate power points

Key specifications

• Configuration: space for three socket modules
• External dimensions: 230 × 100 × 250 mm
• Type: recessed box for installation in insulation layers

How to use

Position the recessed box within the insulation layer at the required height and alignment before fixing the insulation board to the masonry. Cut a recess in the insulation equal to the box dimensions, insert the box so its front face is flush with the finished surface level, and secure it according to the façade or insulation system manufacturer’s instructions. Route supply cables into the box through the designated knockouts or openings, complete the wiring connections following applicable electrical codes, and mount the socket modules into the box. Finish the external surface in line with the wall insulation finishing system.

Usage recommendations

Follow national electrical regulations and the insulation system manufacturer’s guidelines. Verify compatibility of socket modules and conduit entries with the box dimensions and ensure proper sealing around the box to maintain thermal performance of the insulation layer.
