A complete electrical distribution box typically costs between $600 and $4,500, depending on amperage, enclosure type, labor, and installation complexity.

Cost Breakdown

Unit Price:

• Basic 100A residential panel with standard metal enclosure: $400–$700 for the panel alone .
• Upgrading to a 200A service: $1,000–$2,500 for the panel itself, with high-end panels exceeding $2,500 . Installation and Labor:
• Standard residential installation for a 100–125A indoor panel: $1,200–$2,500 including labor and permits .
• 200A outdoor upgrades with new meter sockets: $3,000–$6,000 depending on wiring complexity and local labor rates .
• Labor hours typically range from 4–18 hours, with electricians charging $75–$150 per hour depending on region and project complexity . Additional Costs:
• Permits, inspections, and code upgrades can add $100–$500.
• Complex wiring, long conduit runs, or retrofitting older buildings may increase total costs by 15–20% .
• Optional features like surge protection, smart meters, or premium enclosures can further raise the price .

Factors Affecting Price

1. Amperage Rating: Higher amperage panels (200A vs 100A) cost more due to larger breakers and busbars.
2. Enclosure Material: Plastic, powder-coated steel, or stainless steel enclosures vary in durability and price.
3. Location: Indoor panels are generally cheaper than outdoor panels due to weatherproofing requirements.
4. Regional Labor Rates: Urban areas often have higher labor and permit costs, while rural areas may incur transport fees for specialized panels.
5. Project Complexity: Re-routing wiring, replacing meter sockets, or upgrading service entrances increases both labor and material costs.

Typical Total Costs

• Basic Replacement (100A, 8–12 circuits): $1,100–$1,600 including labor and permits .
• Mid-Range Upgrade (150A, 12–16 circuits): $1,600–$3,200 depending on wiring and local labor .
• High-End Upgrade (200A, 16–20 circuits, outdoor, premium features): $3,000–$4,500 or more . In summary, the price of a complete electrical distribution box varies widely based on panel size, amperage, enclosure type, labor, permits, and optional features, with typical residential projects ranging from $1,100 to $4,500 for a fully installed system.
