Complete List of Egyptian Box-Type Electrical Distribution Box Models

Egyptian electrical distribution boxes include indoor/outdoor low-voltage and medium-voltage models, with specifications governed by EEHC standards, Legrand, and KSA product lines.1. EEHC Standard Distribution BoxesThe Egyptian Electricity Holding Company (EEHC) provides technical specifications for medium-voltage (MV) and low-voltage (LV) distribution boxes under the EDMS (Egyptian Distribution Material Specifications) framework . Key features include:Medium Voltage Ring Main Units (RMU): Gas-insulated (GIS) or air-insulated (AIS), rated for 24 kV systems, ready for motorization and SCADA integration.Compliance Standards: IEC 62271 series for AC switchgear, circuit breakers, disconnectors, and switches.Protection and Safety: IP and IK ratings for ingress and mechanical impact protection, HRC fuses, voltage detecting systems (VDS), and energy management system (EMS) compatibility.Applications: Indoor/outdoor substations, distribution automation, and advanced distribution management systems (ADMS).2. Legrand Distribution CabinetsLegrand offers a range of low-voltage distribution boards suitable for residential, commercial, and industrial applications :Module Capacity: 4 to 72 modules, with 8, 12, 13, 18 modules per row options.Series Examples:Convivio Range: 3-phase distribution boards for houses, villas, offices, and small commercial buildings.XL³ 125: Cabinets with 18 modules per row, extendable up to 36 modules, supporting up to 800 A.XL³ S Range: IP65 and IK09 weatherproof enclosures for industrial applications.Features: Flush mounting, cable sleeves, strong metal enclosures, and integration with other Legrand products.3. KSA Custom and Type-Tested PanelsKSA El-Tholathia specializes in custom low-voltage panels and distribution boxes :Type-Tested LV Panels: Approved by Schneider Electric, ensuring safety, reliability, and performance.Applications: Administrative buildings, banks, water and wastewater projects, industrial facilities.Enclosures: Durable metal housings, IT racks, and ergonomic control desks.Customization: Panels designed to meet project-specific requirements with global certifications.4. Egyptian Electrical Code (ECC) ComplianceAll distribution boxes in Egypt must comply with the Egyptian Electrical Code (ECC) :Voltage Ratings: 220/380 V for LV systems, 24 kV for MV systems.Cable and Breaker Requirements: Minimum cross-sections (1.5 mm² for lighting, 2.5 mm² for outlets, 10 mm² for heavy loads), MCBs per circuit, 30 mA RCCB for wet areas.Earthing: Mandatory with resistance ≤1 ohm at sensitive locations.Standards: Based on IEC 60364 with local modifications.5.
