How to classify the casing of low-voltage distribution boxes

Low-voltage distribution box casings are classified based on material, structure, protection level, and installation type, reflecting their functional and environmental requirements.

Classification by Material

Low-voltage distribution boxes are commonly made from metal or plastic. Metal enclosures, typically steel plates, offer high impact resistance, durability, and corrosion protection, making them suitable for industrial and utility applications. Plastic enclosures are lightweight, chemically resistant, and easier to install, often used in residential or light industrial settings . The thickness of the metal plate also affects mechanical strength and longevity, with thicker plates providing better protection against impacts and environmental factors .

Classification by Structure and Protection

Distribution boxes can be enclosed or semi-enclosed. Enclosed (protective) switchgear provides full protection against accidental contact with live parts, while open or panel-type cabinets may have exposed sides, offering lower protection and typically used in industrial settings with controlled access . The internal arrangement includes circuit breakers, isolation switches, busbars, and measuring instruments, which are organized to ensure safety, easy maintenance, and fault detection .

Classification by Installation Type

Casings are also classified by installation method:

  • Wall-mounted boxes: Compact, suitable for residential or small commercial applications.
  • Floor-standing cabinets: Larger, used in industrial or utility environments where higher capacity and multiple circuits are required .

Classification by System Hierarchy

According to power distribution hierarchy, casings can be categorized as:

  1. Primary distribution equipment (Power Distribution Center): Centrally installed near step-down transformers, handling high output capacity and strict electrical parameters.
  2. Secondary distribution equipment (Distribution Cabinets or Motor Control Centers): Serve scattered or concentrated loads, providing protection, monitoring, and control for connected circuits.
  3. Final distribution equipment (Lighting or End-User Distribution Boxes): Small-capacity boxes located near end devices, often including miniature circuit breakers or residual current devices for safety .

Summary

The casing of a low-voltage distribution box is classified based on material (metal/plastic), structure (enclosed/semi-enclosed), installation type (wall-mounted/floor-standing), and system hierarchy (primary, secondary, final). These classifications ensure that the distribution box meets safety, durability, and operational requirements for its intended environment and application .
