Construction site electrical distribution boxes with sockets typically range from $100 to $500 depending on amperage, number of outlets, and waterproofing features.

Typical Pricing and Features

• Single-phase boxes for small to medium construction sites usually cost $100–$250. These often include 4–6 standard 110V/120V sockets, built-in circuit breakers, and IP44–IP65 waterproof ratings (Amazon example: 60A box with 4 NEMA 5-20 sockets, IP65, around $150–$200) .
• Three-phase or heavy-duty boxes for larger sites or industrial use can range from $300–$500 or more, featuring multiple 230V/400V sockets, integrated FI switches, and higher amperage ratings (16A–32A per socket) .
• Materials and durability affect price: ABS plastic or thermoplastic boxes are lighter and less expensive, while sheet steel or fiberglass enclosures with IP65–IP67 ratings are more robust and costlier .
• Additional features such as built-in electricity meters, voltage/current displays, and lockable lids can increase the price by $50–$100 .

Buying Considerations

1. Amperage and load requirements: Ensure the box can handle the total current of all connected tools.
2. Number and type of sockets: Choose boxes with sufficient 110V/230V outlets or CEE sockets for heavy machinery.
3. Waterproofing and safety: IP44–IP67 ratings protect against dust, rain, and splashes; integrated circuit breakers and FI switches enhance safety.
4. Portability: Lightweight plastic boxes are easier to move, while steel or fiberglass boxes are more durable for long-term use. In summary, for a standard construction site, a single-phase distribution box with 4–6 sockets costs around $150–$250, while larger three-phase boxes for industrial applications can reach $400–$500, depending on features and materials .
