The number of 48-pin junction boxes in a single box varies by manufacturer, but typically ranges from 5 to 20 units per shipping carton depending on size and packaging.

Packaging Considerations

48-pin junction boxes are larger than standard single-gang or small multi-gang boxes, often designed to accommodate multiple wires, terminal blocks, or modular components . Because of their size and weight, manufacturers usually pack fewer units per carton to prevent damage during shipping and to comply with handling standards.

Factors Affecting Quantity

1. Box Dimensions: Larger boxes with greater depth or width reduce the number of units that can fit in a shipping carton .
2. Material: Metal junction boxes are heavier and may be packaged in smaller quantities than plastic boxes to avoid excessive weight.
3. Protective Packaging: Foam inserts, separators, or individual wrapping for delicate components can reduce the number of boxes per carton.
4. Manufacturer Standards: Some suppliers may standardize cartons to contain 10, 12, or 20 units for easier inventory management, while others may customize based on order size.

Practical Advice

• Check Manufacturer Specifications: Always refer to the product datasheet or supplier catalog for exact packaging quantities.
• Consider Shipping and Storage: If planning for installation, account for the space and weight of the cartons.
• Wire-Fill Capacity: Ensure that the 48-pin box can safely accommodate the intended wiring without overcrowding, as this affects both safety and code compliance . In summary, while there is no universal standard, a typical shipping box for 48-pin junction boxes contains between 5 and 20 units, depending on size, material, and protective packaging. For precise numbers, consult the manufacturer or supplier directly.
