Standard installation price of household electrical distribution boxes

The typical cost to install a standard household electrical distribution box ranges from $120 to $560, depending on box type, amperage, and installation complexity.

Cost Overview

For a basic residential installation, a standard single-gang or small distribution box in an accessible indoor location usually costs $120–$260, which includes labor and materials . This range covers straightforward installations with minimal wiring adjustments and standard 120/240V circuits. For mid-range setups, such as a two-gang box with multiple outlets or a small subpanel, costs typically rise to $160–$435, reflecting additional labor, materials, and minor wiring complexity . Labor for these installations generally ranges from 1–2 hours for simple boxes to 2–3 hours for more complex setups, with electricians charging $75–$125 per hour depending on region and expertise .

High-End or Complex Installations

Larger or outdoor-rated distribution boxes, weatherproof enclosures, or installations requiring new circuits and safety features like AFCI/GFCI protection can cost $350–$1,600 or more . Premium setups, including 200A-rated or outdoor meter boxes, may reach $1,000–$2,000, with industrial or custom enclosures exceeding $5,000 in some cases . Factors influencing higher costs include:

• Amperage rating (100A vs 200A)
• Outdoor/weatherproof enclosures
• Number of circuits and box size
• Permit and inspection fees
• Complex wiring or difficult access

Key Considerations

• Box Type: Plastic single-gang boxes are cheapest; metal, deep, or weatherproof boxes cost more .
• Location: Indoor installations are less expensive than outdoor or hard-to-access locations .
• Safety Features: AFCI/GFCI protection adds $150–$300 per box .
• Labor and Permits: Labor dominates cost; permits and inspections can add $50–$200 depending on local regulations .

Summary

For a standard household electrical distribution box, homeowners can expect:

• Basic indoor installation: $120–$260
• Mid-range installation with multiple circuits: $160–$435
• High-end or outdoor/weatherproof installation: $350–$1,600+
• Premium 200A or custom setups: $1,000–$2,000+ Planning ahead and obtaining a line-item quote that separates materials, labor, permits, and safety features helps ensure accurate budgeting and compliance with local electrical codes .
