What are the dimensions of a Dominic low-voltage distribution box

The exact dimensions of a Dominic low-voltage distribution box vary by model, but typical modular low-voltage boxes range from 300–1200 mm in height, 200–600 mm in width, and 100–400 mm in depth.

Typical Size and Modularity

Dominic low-voltage distribution boxes are usually modular, allowing flexibility in design and expansion. Many modular systems use a 192 mm module width standard, which helps in planning the number of circuit breakers or components that can fit inside the enclosure . The height and depth depend on the number of modules stacked vertically and the intended installation type (wall-mounted or floor-mounted).

Installation Considerations

• Wall-mounted boxes are generally shallower (100–250 mm depth) to save space and allow easy access to wiring .
• Floor-mounted or embedded boxes may be deeper (up to 400 mm) to accommodate larger busbars, main switches, or additional protective devices .
• Width is often determined by the number of modules; for example, a 4-module wide box would be approximately 768 mm (4 × 192 mm) plus clearance for the enclosure frame .

Environmental and Safety Factors

When selecting a box, consider IP rating, material, and ventilation. Indoor boxes are typically made of mild steel or plastic, while outdoor boxes may use galvanized steel or aluminum for weather resistance . Ensure the box allows sufficient space for wiring, maintenance, and future expansion.

Recommendation

For precise dimensions of a specific Dominic low-voltage distribution box model, it is best to consult the manufacturer's datasheet or technical catalog, as sizes can vary depending on the number of modules, type of enclosure, and intended application . This ensures compatibility with your installation space and electrical requirements.
