Complete electrical distribution box in Sri Lanka

In Sri Lanka, common electrical distribution boxes include wall-mounted and free-standing metal enclosures, IP65/IP66 waterproof boxes, and high-quality ABS or PC plastic boxes suitable for residential, commercial, and industrial use.

Types of Distribution Boxes

1. Metal Distribution Boxes Metal enclosures, such as those offered by CEYLEKTRA, are widely used in industrial and commercial settings. They are available in wall-mounted or free-standing designs, with customizable thicknesses for durability and strength. These boxes are powder-coated in RAL colors for corrosion resistance and aesthetic appeal, and they comply with IP and IEC standards for safe power distribution. Typical dimensions include 600 × 1000 × 250 mm, with options for cover plates or U brackets for flexible installation (Bianco CEYLEKTRA) . 2. Waterproof Plastic Boxes (IP65/IP66) For outdoor or moisture-prone environments, waterproof distribution boxes are common. These are made from high-quality thermoplastic materials like ABS or PC, offering fire resistance, UV protection, and impact resistance. They feature silicon rubber seals for excellent waterproofing, dustproofing, and corrosion resistance. Holes for cable entry can be customized according to installation needs. Examples include 9-way or 4-way IP66 weatherproof DB boxes suitable for both residential and commercial applications (General Power Electric) . 3. Standard Residential Boxes For home use, smaller distribution boxes are available, typically in sizes like 150 × 150 × 70 mm. These are often IP65-rated, providing basic protection against dust and water ingress, and are suitable for housing terminal junctions and small electrical circuits (HardwareMart, Homemart) .
