How heavy is a distribution box

The weight of a distribution box varies widely, typically ranging from 2–50 kg depending on size, material, and number of circuits.

Factors Affecting Weight

Material: Distribution boxes are commonly made from plastic, polycarbonate, SMC, or metal. Plastic boxes are lightweight, often weighing 2–10 kg, making them suitable for residential or light commercial use . Metal or SMC boxes, used in industrial or outdoor environments, are heavier due to their durability and impact resistance, often weighing 15–50 kg or more . Size and Circuit Capacity: Smaller boxes with 1–6 circuits are compact and light, while larger boxes supporting 12–36 circuits or main distribution boards are significantly heavier due to additional components like busbars, circuit breakers, and fuses . A typical 3-phase industrial distribution box can weigh 30–50 kg, whereas a small residential fuse box may weigh only 2–5 kg . Installation Type: Portable or modular distribution boxes are designed to be lighter for easy handling, often including handles or hooks for suspension . Fixed indoor or outdoor boxes may be heavier due to reinforced enclosures and protective coatings.

Summary

• Small residential plastic box: 2–10 kg
• Medium commercial box (metal or SMC): 10–25 kg
• Large industrial or main distribution board: 30–50 kg or more The exact weight depends on the combination of material, size, number of circuits, and additional components. Always check the manufacturer's specifications for precise weight before installation or transport .
