Level 3 and Level 2 Distribution Boxes for Construction Sites

Level 3 and Level 2 Distribution Boxes for Construction Sites

Level 2 distribution boxes route power from the main distribution to specific zones, while Level 3 boxes provide the final connection to individual equipment with leakage protection.Level 2 Distribution BoxesPurpose and Function: Level 2 distribution boxes, also called secondary distribution boxes, serve as an intermediate power distribution point on construction sites. They receive power from the main (Level 1) distribution box and supply it to specific zones, buildings, or floors, handling three-phase power for machinery, lighting, and other construction loads . Configuration and Components:Equipped with large three-phase circuit breakers for main protection.Includes residual current devices (RCDs) or leakage protection for safety.May have inner and outer doors with a rainproof top for outdoor use.Copper busbars are commonly used for reliable conductivity.Designed to comply with construction electricity standards, ensuring one machine, one switch, one protection . Installation Guidelines:Typically installed 1.5 meters above ground for accessibility.Positioned where electrical loads are concentrated, with a maximum distance of 30 meters to the connected switch boxes .Provides two-level protection when combined with Level 3 boxes, ensuring both zone-level and equipment-level leakage protection .Level 3 Distribution BoxesPurpose and Function: Level 3 distribution boxes, also called tertiary or final distribution boxes, are the last connection point for individual electrical equipment. They deliver single-phase 220V power to tools, lighting, or small machinery and are often portable or fixed depending on site requirements . Configuration and Components:Contains single-phase circuit breakers and leakage protection switches.Ensures individual circuit protection, preventing multiple devices from being controlled by the same switch.May include aviation docking plugs for mobile equipment.Designed for safety, durability, and outdoor use, often with rainproof and dustproof enclosures . Installation Guidelines:Placed under the Level 2 distribution box, with a maximum horizontal distance of 3 meters to the equipment it controls .Supports low-power devices like welding machines, vibrators, or cutting machines.Incoming line size depends on equipment power: e.g., 6mm² copper wire for
