UAE power distribution box dimensions

UAE power distribution boxes come in a variety of sizes, typically ranging from compact residential boxes to large industrial SMDB panels, with depths from 1. 5" to over 2 feet depending on application.

Residential and Commercial Distribution Boxes

For residential and light commercial applications, distribution boxes are generally compact and wall-mounted. Common dimensions include: Square and Octagonal Boxes: Depths of 1-1/2” to 2-1/8”, suitable for switches, receptacles, and lighting circuits. Rectangular Boxes: Depths of 1-7/8” to 2-1/8”, often used for multiple conductor runs and outlet devices.

Knockout Sizes: Typically ½”, ¾”, and 1” to accommodate wiring entry. These boxes are designed for indoor installation, providing safe housing for MCBs, RCDs, and wiring, with modular DIN-rail mounting options for easy configuration.

Industrial and Heavy-

Duty Panels

For industrial or large commercial projects, Sub Main Distribution Boards (SMDB) and Main Distribution Boards (MDB) are used. Typical features and dimensions include: Ratings: Up to 800A, with incomers from 100A to 800A and outgoings from 30A to 630A. Enclosure: Electro-galvanized steel, powder-coated, suitable for floor or wall mounting.

Protection: IP65 rating for dust and water resistance, suitable for harsh UAE environments. Cabling Space: Ample room for top, bottom, and side cable entry, with busbars color-coded and insulated. Physical Size: While exact dimensions vary by manufacturer, industrial SMDB panels can range from 0.

6m to 2m in height, 0. 4m to 1. 2m in width, and 0.

2m to 0. 6m in depth, depending on the number of ways and amperage requirements.

Key Considerations

When selecting a distribution box in the UAE: Voltage and Current Ratings: Ensure compatibility with system voltage (e.g., 415V three-phase) and total load.

Short-

Circuit Capacity: Must meet or exceed prospective fault currents to prevent failure. Environmental Factors: High temperatures, humidity, and dust in the UAE require IP-rated, corrosion-resistant enclosures. Future Expansion: Plan for 20–25% spare capacity in outgoing ways to accommodate additional circuits.

In summary, UAE power distribution boxes vary widely in size depending on application, from compact residential boxes with depths around 1. 5–2. 1 inches to large industrial SMDB panels exceeding 2 feet in depth, with modular designs and robust enclosures to meet local environmental and safety standards.
