Estimating a sub panel install cost involves weighing panel size, wiring, labor, and permitting. Typical total prices hinge on amperage (60A–100A), distance from the main service, wiring type, and region. This article delivers practical price ranges and per-unit costs to help buyers budget accurately for a sub panel installation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total installed cost | $800 | $1,800 | $3,400 | Assumes 60–100A sub panel with basic wiring |
| Sub panel enclosure (historic vs. new) | $100 | $250 | $450 | Includes main breaker space and finish |
| Feeder cable (4/3 or 2/2 type) | $150 | $350 | $700 | Per 10–20 ft run; copper varies by gauge |
| Breaker(s) | $25 | $60 | $120 | Each branch breaker |
| Meter socket / main disconnect (if needed) | $200 | $400 | $900 | May be required for certain installations |
| Labor (electrician) | $400 | $900 | $1,800 | 2–6 hours depending on complexity |
| Permits | $50 | $150 | $500 | Local jurisdiction fees |
| Discovery/rework / diagnostics | $50 | $150 | $350 | Contingency for access issues |
Assumptions: Midwest labor rates, standard copper feeder wiring, normal attic/basement access, and no substantial panel upgrades.
Sub Panel Install Cost by Box Size and Amperage
Costs vary with amperage and enclosure size, with 60–100A sub panels priced distinctly. A 60A install usually falls near the low end, while 100A with a larger enclosure pushes toward the middle. Per-unit feeder pricing often scales with gauge and distance.
| Scenario | Enclosure Size | Feeder Type | Total Range | Notes |
|---|---|---|---|---|
| 60A in 14–16 space panel | Small | 4/3 Cu | $800-$1,400 | Basic install, short run |
| 100A in 24–32 space panel | Medium | 4/0 Cu or 2/0 Cu | $1,400-$2,600 | Longer run, additional breakers |
| 100A with modern enclosure upgrade | Large | Cu feeder + new main | $2,200-$3,400 | Code-compliant upgrades |
Major Cost Components in a Sub Panel Setup
Understanding the parts of the quote helps compare bids accurately. The typical components include Materials, Labor, Permits, and Delivery/Disposal. A detailed quote shows each line item so budget decisions are clear.
| Component | Low | Average | High | What affects it |
|---|---|---|---|---|
| Materials | $180 | $420 | $750 | Panel, breakers, feeder, conduit |
| Labor | $320 | $700 | $1,150 | Wiring, connections, mounting |
| Permits | $50 | $150 | $500 | Town/county requirements |
| Delivery/Disposal | $20 | $60 | $120 | Material haul and waste fees |
| Misc / Contingency | $30 | $80 | $200 | Access issues, code fixes |
Variables Driving the Final Sub Panel Quote
Two key drivers often push costs up or down: distance to the main service and panel rating. Longer feeder runs require larger gauge conductors and more conduit, which increases both materials and labor. Regional permitting stringency and electrical code interpretations also shift pricing by several hundred dollars.
Practical Ways to Trim Sub Panel Price Without Sacrificing Safety
Smart planning and scope control can reduce total cost. Consider aligning the sub panel location with existing conduit, using standard breaker sizes, and avoiding upgrades to the main service unless necessary. Scheduling in off-peak seasons and requesting itemized bids helps control price.
Regional Price Differences for Sub Panel Projects
Prices can swing by region due to labor markets and permit fees. In the Southeast, expect mid-range bids; in the Northeast, permit costs and dense wiring may lift totals. Rural areas often show lower labor rates but added travel fees.
Labor and Scheduling Details for a Typical Sub Panel Install
Most installs require 2–5 hours of skilled labor per crew, depending on access and complexity. Larger homes or remodels can demand longer timelines and possible overtime rates. Coordination with other trades may add minor costs.
Durability and Warranty Considerations in the Price
Warranty length and coverage influence price moderately. Most electricians include a 1–2 year workmanship warranty, with equipment warranties applying to components. Extended protection adds cost but can improve long-term value.
Two Quick Quote Examples by Scenario
These illustrative quotes show realistic ranges with assumptions.
| Scenario | Amperage | Run Length | Materials | Labor | Total |
|---|---|---|---|---|---|
| New 60A sub panel in a single-story home | 60A | 15 ft | Small enclosure, Cu feeder | 2 hours | $1,000-$1,350 |
| 100A sub panel for detached garage | 100A | 40 ft | Medium enclosure, Cu feeder, extra breakers | 4–5 hours | $2,150-$3,200 |
