How many specifications are available for distribution boxes

Distribution boxes come in numerous specifications, including over a dozen functional types and multiple technical models for residential, commercial, and industrial applications.

Functional Types of Distribution Boxes

Distribution boxes are categorized based on their application and installation environment:

• Single-Phase DB Boxes: Designed for residential or small commercial loads, typically lower power capacity .
• Three-Phase DB Boxes: Used in industrial or large commercial facilities requiring higher power capacity .
• Surface-Mounted DB Boxes: Installed directly on walls, suitable for retrofits and industrial environments .
• Flush-Mounted DB Boxes: Embedded into walls for a clean appearance, common in residential and commercial buildings .
• Pole-Mounted DB Boxes: Outdoor use for street lighting or utility applications .
• Lighting Distribution Boxes: Dedicated to lighting circuits with protective devices .
• Power Distribution Boxes: Support sockets, equipment, and heavy machinery .
