Dimensions of Saudi Arabian Home Electrical Distribution Boxes

Electrical distribution boxes in Saudi Arabia come in a variety of standard sizes, typically ranging from compact wall-mounted units to large floor-standing modular enclosures, with dimensions tailored to residential, commercial, and industrial applications.

Standard Wall-Mounted and Floor-Standing Enclosures

Electrical distribution boxes are available in wall-mounted and floor-standing configurations. Wall-mounted boxes are designed for minimal space occupation, while floor-standing enclosures allow for larger, high-performance panel configurations . Typical dimensions for these enclosures vary depending on the number of circuits and components:

• Wall-mounted enclosures: Common heights range from 300 mm to 1200 mm, widths from 200 mm to 600 mm, and depths from 100 mm to 400 mm .
• Floor-standing modular cabinets: Heights can range from 1200 mm to 2200 mm, widths from 600 mm to 1200 mm, and depths from 400 mm to 800 mm .

Meterboxes and Residential Distribution Boxes

For residential applications, meterboxes with steel enclosures are widely used. These are designed for outdoor installation and must withstand high temperatures and direct solar radiation . Typical dimensions for single or double meterboxes include:

• Single meterbox: Approximately 400 mm height × 300 mm width × 150 mm depth
• Double meterbox: Approximately 400–500 mm height × 500–600 mm width × 150–200 mm depth These boxes are usually made of stainless steel (grade 304) or corrosion-resistant steel, with thicknesses ranging from 0.9 mm to 1.1 mm . They are designed to meet SASO and IEC standards, ensuring durability in Saudi Arabia's hot, dry, and dusty climate .

Industrial and Custom Enclosures

For industrial or commercial applications, modular steel enclosures allow up to 600 different combinations of height, width, and depth, depending on the required configuration . ABB and Schneider Electric offer pre-galvanized steel or stainless steel enclosures with adjustable lugs, knockouts, and options for surface or flush mounting . These enclosures can accommodate:

• Voltage ratings: 220–440 VAC, 50–60 Hz
• Protection ratings: IP66 for dust and water ingress, IK10 for mechanical impact
• Customizable dimensions: Heights up to 2200 mm, widths up to 1200 mm, depths up to 800 mm

Key Considerations

When selecting a distribution box in Saudi Arabia, consider:

• Compliance with SASO standards for safety and fire resistance
• Material suitability for high temperatures and dust exposure
• Mounting type (wall-mounted vs. floor-standing)
• Capacity for future expansion or smart monitoring features These dimensions and configurations ensure that electrical distribution boxes are safe, durable, and suitable for residential, commercial, and industrial installations in Saudi Arabia.
