Subfloor deep junction box electro base NOZARKARBA D73×73 mm 650C E-A.0006P/68

The electro base deep subfloor junction box NOZARKARBA D73×73 mm 650C is designed for recessed installation beneath floor surfaces to house and protect electrical connections. It provides a sealed, accessible cavity for wiring splices and terminals where floor-level access points are required. Constructed for installation in residential and commercial environments, the box accommodates standard cable entries and is intended to work with compatible floor covers and conduits.

Advantages

This subfloor junction box offers a compact footprint and a deep internal volume that facilitates safe containment of multiple conductors and standard terminal blocks. The product is built to resist mechanical strain from floor fixtures and provides reliable alignment for cover plates. Its design supports straightforward installation in new construction and renovation projects, minimizing the need for extensive floor modification.

Suitable for

• Housing wiring splices and junctions beneath wooden, concrete or tiled floors
• Providing floor-level access points for power, data or control cabling
• Use in residential apartments, office spaces, retail fit-outs and light commercial buildings
• Installation during renovations where concealed but serviceable connections are required

Key specifications

• Shape and nominal dimensions: approximately 73 × 73 mm footprint with a deep internal cavity
• Internal depth: designed to accommodate multiple conductor splices and small terminal blocks
• Material: durable insulating polymer suitable for in-floor electrical applications
• Temperature rating: designed for continuous use up to specified elevated temperature class
• Mounting method: recessed installation beneath floor coverings with provision for securing to substrate

How to use

Position the junction box in the prepared recess of the subfloor, ensuring the opening aligns with the intended floor access point. Route cables into the box through appropriate entries or conduit, leaving sufficient conductor length for making splices or attaching terminals. Make all electrical connections following local regulations and standard wiring practices, then secure any internal components and fit the compatible floor cover or plate. Verify the installation is flush with the finished floor and that the cover provides the required level of protection.

Usage recommendations

Install and inspect this product according to applicable electrical codes. Use compatible covers and gaskets to maintain mechanical protection and dust resistance. Avoid overfilling the box beyond its safe conductor fill capacity, and choose appropriate cable glands or conduit adapters for the floor type to prevent strain on connections.
