The typical price for installing a 50 amp sub panel varies by labor, materials, and local codes. This guide lays out the main cost drivers, provides realistic price ranges in dollars, and helps buyers plan a budget for a standard residential upgrade.
Assumptions: region, panel type, wire gauge, distance from the main panel, and crew scope.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Supply & Material | $150 | $350 | $800 | New panel enclosure, breakers, lugs, feeders |
| Labor | $600 | $1,200 | $2,000 | Electrical contractor labor for install |
| Permits | $0 | $150 | $500 | Local permit and inspection fees |
| Delivery/Disposal | $25 | $75 | $150 | Transport and cleanup |
| Materials & Misc | $75 | $200 | $350 | Conduits, connectors, bonding, hardware |
| Overhead & Profit | $100 | $200 | $400 | Included by contractor |
Overview Of Costs
Cost to install a 50 amp sub panel typically ranges from about $800 to $3,000, with most projects clustering around $1,200 to $2,000. The exact price depends on feeder length, panel type, whether a main breaker or disconnect is required, and local permit costs. Per-unit considerations include roughly $4 to $6 per linear foot of feeder conductor and $150 to $350 for each new breaker installed.

What Drives Price
Feeder distance from the main panel is a major driver; longer runs require more conduit, more wire, and potential trenching or ceiling/attic routing. Panel features such as a main breaker in the sub panel, AC disconnects, and the number of circuits influence the cost. Wiring type and gauge also matter: 6 AWG copper feeders for outdoor runs or longer distances typically cost more but are required for safe operation.
Cost By Region
Regional differences affect labor rates and permit costs. In the Northeast, totals often trend toward the higher end due to stricter regulations and higher labor rates, while the Midwest may be mid-range, and the South can be lower on average. Expect regional deltas of roughly ±15 to ±30 percent depending on urban versus rural areas.
Labor, Hours & Rates
Labor for installation typically spans 4 to 12 hours for a standard home scenario. A small sub panel with short feeders and kit wiring may fall on the lower end, while longer runs, outdoor installations, or required trenching raise the time and cost. Estimated range for labor is $600 to $2,000, with most common projects around $1,000 to $1,500.
Regional Price Differences
Three typical U.S. market profiles show variation:
- Urban Northeast: higher costs due to permitting and labor, often $1,800 to $3,000 total.
- Suburban Midwest: mid-range, commonly $1,200 to $2,000.
- Rural South: lower end, sometimes $900 to $1,600.
Additional & Hidden Costs
Possible extras include upgrading service to accommodate a sub panel, adding upgraded grounding, or extending a feeder through finished spaces. Hidden costs might appear from required trenching, weatherproofing outdoor runs, or adding a dedicated disconnect switch for code compliance.
Pricing Variables
Exact price hinges on several select factors. Distance from main panel and whether indoor or outdoor routing greatly affect conduit and weatherproofing needs. If a permit is required, expect a delay as inspections are scheduled and passed. Also, some jurisdictions require a dedicated disconnect at the sub panel, which adds a modest extra charge for hardware and labor.
Real-World Pricing Examples
Three scenario snapshots illustrate typical outcomes. Assumptions: single-family home, standard 120/240 V service, copper feeders.
- Basic: 6 ft feeder, indoor, standard panel with 6 circuits. Labor 6 hours; materials modest. Total around $900-$1,400. Per-unit: $150-$250 for materials, $60-$120 per hour for labor.
- Mid-Range: 20 ft feeder, outdoor crawlspace, main breaker in sub panel, 10 circuits. Labor 8–10 hours; higher material quality. Total around $1,600-$2,200. Per-unit: $200-$350 materials, $90-$150 per hour labor.
- Premium: 40 ft feeder, trenching, weatherproof enclosure, 16 circuits, additional grounding upgrade. Labor 12–16 hours; premium parts. Total around $2,800-$3,800. Per-unit: $300-$500 materials, $100-$180 per hour labor.
What To Ask Your Contractor
When evaluating bids, compare itemized totals and verify included components. Ensure permits, inspections, and disposal are clearly listed. Clarify feeder type, gauge, and whether a main breaker is included in the sub panel package to avoid surprises later.
