Typical Price Ranges

• Residential hollow boxes: Basic single-phase boxes for home use generally cost $20–$80, depending on the number of circuits and material (plastic or PVC) .
• Commercial or industrial distribution boxes: Larger three-phase or multi-circuit boxes with metal or fiberglass construction can range from $100 to $500 or more, especially if they include advanced features like smart monitoring, weatherproofing, or IP-rated enclosures .

Factors Affecting Price

1. Material: Plastic/PVC boxes are cheaper but less durable; metal (aluminum or stainless steel) and fiberglass boxes are more expensive but offer higher strength and weather resistance .
2. Capacity and Size: Larger boxes with more circuit slots or modules cost more. For example, a 32-module underfloor outlet box has specialized dividers and supports, increasing its price .
3. Installation Type: Outdoor-rated or weatherproof boxes carry a premium due to additional sealing and corrosion resistance .
4. Features: Advanced features like smart monitoring, remote control, or integration with building management systems increase cost .
5. Bulk Orders: Purchasing in larger quantities or through distributors can lower the per-unit price .

Summary

For budgeting purposes, small residential hollow boxes can be expected around $20–$80, standard commercial boxes around $100–$300, and high-end industrial or customized units may exceed $500.
