Number 6 Wire Price: Cost to Buy and Install in the United States 2026
Prices for Number 6 wire vary by copper type, insulation, and installation method. Buyers typically pay for the wire length, insulation class, and any labor costs to pull or run the wire through conduit. The cost drivers include gauge specification, whether the wire is THHN, NM-B, or UF-B, region, and whether a permit is required. This article presents practical price ranges in USD and breaks down the major components to help plan a budget for Number 6 wire purchases and installation.
Assumptions: Midwest labor rates, standard copper THHN in conduit, normal access, typical residential or light commercial projects.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Number 6 wire (per foot, copper THHN in conduit) | $0.65 | $1.05 | $1.35 | Insulated copper, single conductor, standard “in conduit” runs |
| Wire spool (OHG) | $320 | $520 | $760 | 500 ft to 1000 ft reels common |
| Labor for pulling/install (per hour) | $70 | $95 | $125 | Electrician or helper; varies by region |
| Per run installation cost (typical 50–100 ft run) | $250 | $400 | $800 | Includes trenching or conduit work in some cases |
| Permits and inspections | $50 | $150 | $400 | Depends on jurisdiction |
| Conduit and fittings (if required) | $0.50 | $1.20 | $2.00 | PVC or EMT; per foot or per run |
Typical Price for Number 6 Wire by Length and Type
For a straightforward residential run using copper Number 6 THHN in conduit, buyers commonly see wire pricing in the range of $0.75 to $1.35 per foot. When ordering by the roll, a 500-foot spool tends to fall between $320 and $520, while larger 1,000-foot reels can range from $520 to $760 depending on the supplier and insulation class. In practice, most homeowners budget $450 to $900 for 100–200 feet of Number 6 wire installed with conduit and standard fittings to complete a typical branch circuit or feeder run. If the job uses NM-B or UF-B cable, expect higher per-foot costs due to different insulation and installation requirements.
Assumptions: single conductor THHN in conduit, average quality connector fittings, standard climate conditions.
Cost Components That Shape the Quote
The total price breaks down into four to six core parts. The following table shows how charges commonly appear on a formal quote for Number 6 wire projects.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $0.65/ft | $1.05/ft | $1.35/ft | Wire plus insulation; include conduit if needed |
| Labor | $70/hr | $95/hr | $125/hr | Journeyman electrician rate varies by region |
| Conduit and fittings | $0.50/ft | $1.20/ft | $2.00/ft | PVC or metal conduit; includes connectors |
| Permits | $50 | $150 | $400 | Jurisdiction-dependent |
| Delivery/Delivery window | $0 | $25 | $60 | Distance-based |
| Labor overhead and overhead | $0 | $20 | $60 | Project management and admin |
Formula example: Total estimated labor cost = labor hours × hourly rate to illustrate how the short-run cost scales with run length and complexity.
What Variables Most Change the Final Quote
Two major drivers consistently move Number 6 wire pricing higher or lower. The first is run length and routing complexity. Longer runs that require multiple pulls, additional conduit sections, or trenching add labor hours and material costs. The second is the system type and insulation class. THHN in conduit is typically cheaper than NM-B for long, exposed runs but may require more conduit and fittings, while UF-B for outdoor or damp locations can alter both materials and labor estimates.
Small projects under 50 feet are often at the lower end, while 100–200 feet with multiple bends and a mix of conduit and fittings can push the price into the average-to-high range.
Regional Differences You Should Expect
Prices vary by region due to labor rates and permit costs. The Northeast and West Coast tend to have higher labor rates and more rigorous permit processes. The Midwest and Southeast usually fall into the mid-range for both materials and labor. When comparing quotes, consider local weather impact on installation time, access to the job site, and supplier proximity for quick-turn pricing. Regional deltas can push overall project costs up to 15–25% between markets depending on the exact location and local rules.
How Labor Time Affects the Bottom Line
Labor is often the second-largest expense after materials. A straightforward Number 6 wire pull for a single run can take 2–6 hours, depending on access, obstruction removal, and whether a trench or trenchless approach is chosen. Larger residential feeds or commercial feeders with multiple runs may require 1–2 days of labor. Labor hours plus prevailing hourly rates determine the majority of the installed price.
Scenario: Replacing a Dedicated 60-Amp Feeder with Number 6 Wire
In a typical feeder replacement, electricians pull 40–80 feet of Number 6 copper through dedicated conduit, plus fittings and a permit. Wire cost can range from $0.80 to $1.30 per foot, while labor might run $95–$125 per hour. A mid-sized project could total between $700 and $1,900, depending on permit requirements and the need for trenching or surface-mounted raceways. Expect higher totals if a major service panel update is needed.
Residential Versus Light Commercial: A Cost Comparison
Residential layouts usually involve shorter runs, simpler routing, and fewer permits, leading to lower overall costs. Light commercial projects may demand longer runs in conduit, more fittings, and stricter inspection criteria. Wire pricing per foot remains similar, but installation time and permit fees can push the final price higher for commercial jobs. Commercial projects often require more protective conduit and a higher labor rate, increasing total costs.
Strategies That Lower the Number 6 Wire Price
Cost-savings can come from several angles: selecting the smallest acceptable conductors and insulation class, bundling multiple wires under a single conduit run, planning the routing to minimize bends, and coordinating installation to weather windows with lower labor availability. If a portion of the run can be pre-fabricated in a shop, a reduction in field labor may follow. Careful scope control often yields the most reliable reductions.
Three Realistic Quote Scenarios for Comparison
- Scenario A: 60 ft run, copper THHN in conduit, Midwest, single-channel, no trenching. Wire $0.85/ft; labor 3 hours at $95/hr; conduit and fittings $0.75/ft; permits $100. Estimated total: $380–$640.
- Scenario B: 150 ft run, NM-B alternative, suburban Southeast, moderate routing, small trench. Wire $1.20/ft; labor 6 hours at $100/hr; conduit $1.50/ft; permit $200. Estimated total: $1,100–$1,900.
- Scenario C: 300 ft run, multiple bends, outdoor use UF-B, West region, trench and panel upgrade. Wire $1.30/ft; labor 12 hours at $125/hr; conduit and fittings $2.00/ft; permit $350. Estimated total: $4,000–$6,500.
Assumptions: standard weather window, supplier stock on hand, no emergency rush.
Operational Tips to Sharpen Your Budget Before Ordering
Request several formal quotes with itemized line items for wire, conduit, fittings, labor, and permits. Ask for a per-foot wire price and a per-run installation rate to compare both approaches. If possible, specify a single material path (e.g., Number 6 THHN in conduit) to avoid mismatched substitutions. Compare lead times and delivery charges, especially for larger spools. Ask contractors to show a current price worksheet with line-item components.
Appendix: Quick Reference Per-Unit Ranges
Number 6 wire (copper, THHN in conduit): $0.65–$1.35 per foot. Spool pricing for 500 ft: $320–$520. Labor (electrician): $70–$125 per hour. Conduit and fittings: $0.50–$2.00 per foot. Permits: $50–$400 depending on jurisdiction.
Understanding these ranges helps buyers gauge proposals and avoid surprises. The price for Number 6 wire presents a balance between material quality, installation complexity, and local regulatory requirements, and knowing the ranges supports more accurate budgeting and quote comparison.
